1 Module Description The Series 90–70 Remote I/O Scanner consists of a single circuit board, with a hinged door which serves as a faceplate. It occupies one slot in a Series 90–70 I/O rack.
1 LEDs The Remote I/O Scanner has three LEDs that show through the transparent portion at the top of the door. Module OK lights to indicate that the module has passed its powerup diagnostic tests. If this LED flashes, it indicates a problem, as shown in the table below. If this LED is off, there is a fatal error, which causes the Remote I/O Scanner to go to stop/faulted mode. I/O Enabled lights when the Remote I/O Scanner is receiving the expected output data from the CPU.
1 Required Equipment The following equipment is required to use a Remote I/O Scanner. H At least one Series 90–70 5–slot or 9–slot remote rack with Power Supply. A remote drop may include multiple racks and power supplies. H If a Genius Hand–held Monitor will be used to configure or monitor a remote drop, it must be version 4.0 (IC660HHM501G) or later. H If Logicmaster 90–70 configuration software will be used to configure the remote drop, it must be release 3.0 or later: A. IC641SWP701F (3.
1 Parts of a Remote Drop Together, a Remote I/O Scanner and the modules it serves make up a remote drop on the Genius bus. The remote drop may consist of one to eight Series 90–70 racks. REMOTE DROP a44875 RACK 0 Î P S RACK 1 Î S B C T A M N N E R P S B R M RACK 6 ÎÎ P S B R M RACK 7 ÎÎ P S B R M Î UP TO 50 FEET GENIUS BUS NOTE: ALL RACKS MUST BE AT THE SAME GROUND POTENTIAL Multiple Racks When there are multiple racks, the Remote I/O Scanner must be located in the first rack (rack 0).
1 Series 90–70 Racks Any of the following racks can be used in a remote drop: H H H 5–slot, panel mount rack (IC697CHS750). 9–slot, panel mount rack (IC697CHS790). 9–slot, rack mount rack (IC697CHS791). Each of these racks has an additional, wider slot for a Power Supply. Rack sizes may be mixed in a system installation to suit the requirements of your application. The rack–mount Series 90–70 rack has flanges on the front for mounting on 19–inch standard instrument rack hardware.
1 Series 90–70 Power Supplies These Series 90–70 Power Supplies can be used in a remote drop: H H H H IC697PWR710, 120/240 VAC input, +5 VDC output, 55 Watts (shown below) IC697PWR711, 120/240 VAC input, +5 VDC, +12 VDC, –12 VDC output, 100 Watts IC697PWR721, 24VDC input, +5 VDC, +12 VDC, –12 VDC output, 90 Watts IC697PWR731, 125VDC input, +5 VDC, +12 VDC, –12 VDC output, 60 Watts a42818 LED ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ ÎÎ MODEL 70 POWER SUPPLY MODULE INPUT 120/240V AC
1 Powering Two Racks from a Single Power Source Except for the 125VDC supply, each of these power supplies can be used to power two racks if the total current requirement for both racks does not exceed the power supply’s load capacity. The rack that does not contain the Power Supply must not have a load greater than 5.2 amps.
1 Series 90–70 Modules for a Remote Drop The table below lists modules that can be placed in a remote drop, and gives their catalog numbers, I/O capacities, and loads. Module Catalog Number I/O Points or Channels IC697BEM733 IC697BEM713 IC697BEM711 Module Description Load in Amps at +5 VDC RemoteI/O Scanner Bus TransmitterModule Bus Receiver Module 0.80 1.40 0.
1 Analog Modules: The maximum number of analog input modules that can provide input data to the host is 8; however, there may be additional modules in the remote drop configured outside the Remote I/O Scanner’s I/O map. The maximum number of analog input modules that can be configured for a remote drop is 29. Similarly, while the maximum number of analog output modules that can receive output data from the host is 16, as many as 54 can be configured for a remote drop.
1 Genius Bus The Genius bus is an industrially–hardened Local–Area–Network (LAN). It passes I/O (control) data and background information (datagrams) between the Remote I/O Scanner and a Genius bus controller. The communicated data is protected from environmental interference and corruption in several ways. Each byte is triply–encoded during transmission, and each message is checksummed with a cyclic redundancy check (CRC).
1 Timing A fully–loaded (128 input bytes and 128 output bytes) remote drop adds at least 20mS to the bus scan. The table below shows the bus scan time contribution, at each baud rate, for remote drops with a total of 16, 32, 64, 128, and 256 bytes (fully–loaded), when the Remote I/O Scanner receives outputs from only one bus controller at a time. Total Amount of Input and Output Data for Remote Drop Contribution time in mS at each baud rate * 153.6 Kb std 153.6 Kb ext 76.8 Kb 38.4 Kb 16 bytes 2.
1 Number of Remote Drops on a Bus The number of remote drops on a bus depends on the baud rate and the total number of I/O points in the remote drops. Since the maximum Genius bus scan time is 400mS, and the bus scan time contribution of one fully–loaded remote drop is 20mS, only twenty fully–loaded remote drops are supported on a single bus that operates at 153.6 Kbaud. If remote drops are not fully–loaded, more may be used on a bus operating at these baud rates.
1 Redundancy The Remote I/O Scanner can be used with CPU redundancy, bus redundancy, or both. The suitability of redundancy features for any system depends on the requirements of the application. For Series 90–70 PLC CPUs that are release 3 and earlier, some types of redundancy are not supported. CPU Redundancy Genius devices are considered to be controlled by the Bus Controller that sends them outputs. In CPU redundancy, two Bus Controllers on the same bus can send control outputs at the same time.
1 Genius Bus Redundancy In Genius bus redundancy, there are two bus cables each connected to a Bus Controller. The device communicates on only one bus at a time. Before the alternate bus can be use for communications, a bus switchover must occur and the device must “log in“ with the Bus Controller(s) on the alternate bus. Bus switching can be handled by a Bus Switching Module attached to a Genius block, or by a Remote I/O Scanner (IC697BEM733 rev. B or later) which contains a built–in bus switching relay.
1 Redundant Bus Configuations Many different redundant bus configurations are possible. Three basic ways of using a Remote I/O Scanner with a redundant bus are described below. H A Remote I/O Scanner can be installed directly on both cables of the dual bus pair. The Remote I/O Scanner is configured to operate as a bus switching device in addition to performing its normal remote drop functions. Here, two single–rack remote drops are installed on a dual bus.
1 H A Remote I/O Scanner can be located on a bus stub. The bus switching device to which the bus stub is connected can be another Remote I/O Scanner, as shown below, or a Genius block with a Bus Switching Module attached. In this example, there are two remote drops installed directly on a dual bus. A third remote drop and some Genius blocks are installed on a bus stub connected to one of the Remote I/O Scanners. That Remote I/O Scanner acts as the bus switching device.
1 Configuration A remote drop can be fully configured using Logicmaster 90–70, or automatically configured using a Genius Hand–held Monitor. Differences between the two methods are explained below. Optionally, a previously–configured remote drop can be reconfigured using datagrams. Remote Drop Configuration with Logicmaster 90–70 Logicmaster 90–70, release 3.0 or later can be used to configure a remote drop for any type of host. Either serial or parallel Logicmaster can be used.
1 Configurable Features The following table summarizes configuration options for a remote drop, and compares them to the PLC configuration required with a remote drop. The remote drop can be configured, or reconfigured, using Logicmaster 90–70 or a Genius Hand–held Monitor, or datagrams. If the configuration is not protected, as explained on the next page, a reconfiguration will replace part or all of an existing configuration, regardless of the configuration method originally used.
1 Configuration Protection After configuring a Remote Drop, it is important to prevent inadvertent change while the system is in operation. For this reason, Logicmaster 90–70 automatically protects any configuration you download to a Remote I/O Scanner. A configuration done with a Hand–held Monitor should be protected as described in chapter 6.
Chapter 2 2 Installation section level 1 1 figure bi level 1 table_big level 1 This chapter describes procedures for installing the racks and modules in a remote drop, grounding equipment, connecting the Genius bus, completing SNP connections, and attaching a programmer. Hardware Packaging Each Series 90–70 rack is shipped in its own carton, without a power supply. The power supply and all of the Series 90–70 modules are shipped in individual boxes.
2 System Grounding Procedures All components of a control system and the devices it is controlling must be properly grounded. H Ground conductors should be connected in a tree fashion with branches routed to a central earth ground point. This ensures that no ground conductor carries current from any other branch. This method is shown in the figure shown below. H Ground conductors should be as short and as large in size as possible.
2 Rack Installation Install the rack(s) in the orientation shown below. The illustration shows a 9–slot rack, but a 5–slot rack could be used. Series 90–70 PLC racks may be rack or panel mounted, depending on version ordered. Rack dimensions for installation purposes are shown below. The Series 90–70 rack does not require a fan as long as sufficient space is left around the rack for cooling airflow. a42139 WITH OPTIONAL VME J2 BACKPLANE KIT 1.00 (25.4) 7.
2 Rack Grounding H Complete safety and reference ground connections from the GND terminal on the rack to earth ground using minimum AWG #12 wire and a ring terminal. Use of a nut and star washer for each wire on the GND lug is recommended to ensure adequate grounding. Warning If the ground lug on the rack is not connected, the rack is not grounded. The rack must be grounded to minimize electrical shock hazard which may result in severe personal injury or may be fatal.
2 Do not confuse this rack number with the Device Number used by a Remote I/O Scanner. Rack number refers to a rack’s position within a remote drop. A Device Number is a Remote I/O Scanner’s assigned ID on the Genius bus. These two numbers are not related. The following example shows rack numbering for three remote drops. The Remote I/O Scanners for those remote drops are configured to use Device Numbers 7, 8, and 9. Do not select duplicate rack numbers in the same remote drop.
2 Power Supply Installation After setting the rack number selection jumpers, install the power supply as instructed in its datasheet. An AC power supply installs directly in the leftmost slot of the rack. For DC power supplies, a Power Supply Adapter installs in the leftmost slot. The DC power supply itself can either be installed on the side of the rack or used as a freestanding module up to 20 inches from the adapter module.
2 Module Locations Follow the guidelines below when planning module locations in a remote drop. Remote I/O Scanner Locate the Remote I/O Scanner in rack 0, slot 1, next to the power supply. Bus Transmitter Module A Bus Transmitter Module (BTM) can be located in any slot of rack 0; however, there must be no empty slots between the Bus Transmitter and the Remote I/O Scanner. It is recommended that the Bus Transmitter be located in slot 2, next to the Remote I/O Scanner.
2 Module Installation and Removal Warning Always be careful working near the power supply and the wiring to I/O boards in the rack. Be sure a protective faceplate cover is installed on each board. Voltages present on I/O wiring and power supply could cause severe or fatal injury to personnel. Caution Do not insert or remove a module when power is applied to the rack. This could cause the system to stop.
2 Field Wiring to I/O Modules Basic procedures for completing module wiring are given on the next page. For additional information about installing a specific module, please read the module datasheet.
2 1. Open the hinged door on the module to access the jackscrew which holds the terminal board securely in place. Remove the terminal board by turning the jackscrew counter–clockwise until it is fully disengaged. 2. Remove the terminal board by grasping the top and swinging it outward.
2 Multiple Racks in a Remote Drop If the remote drop has more than one rack, rack 0 must contain a Bus Transmitter Module. The Bus Transmitter should be installed in slot 2, next to the Remote I/O Scanner. Using the appropriate cable (see the table below), attach the bottom connector of the Bus Transmitter to the top connector of a Bus Receiver Module in the next rack. Continue this process to connect all of the racks in the drop.
2 Genius Bus Connections: Single Bus Cable To install the Remote I/O Scanner on a single bus cable, use the upper four terminals as described below. Do not use the lower eight terminals. a44754 CONNECT BUS TO TOP FOUR TERMINALS NOT USED FOR SINGLE–CABLE BUS 1. 2. 3.
2 Genius Bus Connections: Dual Bus Cables To install a Remote I/O Scanner directly on both busses of a redundant bus, use the lower eight terminals as described below. Do not attach an external Bus Switching Module to a Remote I/O Scanner.
2 Connecting a Bus Stub to a Remote I/O Scanner A bus stub must always be Belden 9182 or equivalent cable, regardless of the cable type used for the dual bus trunk.

The total length of all stubs on a bus should be 100 feet or less.
2 Programmer Connection at the Remote I/O Scanner A Logicmaster 90–70 programmer can be connected to rack 0 of a remote drop. (Logicmaster 6 or Logicmaster 5 cannot be used with a remote drop). Refer to the instructions that follow, for the type of equipment you are using.
2 Logicmaster 90 Serial Version and Workstation Interface Board If the programmer is equipped with the serial version of Logicmaster 90–70 and a Workstation Interface Board (IC647WMI920 for Workmaster II or IBM PS/2 computer, or IC640WMI910 for a Workmaster or IBM PC–XT/AT computer), connection is made to the Remote I/O Scanner’s RS–485 serial port. If the Remote I/O Scanner is not part of a multidrop network, follow the instructions below.
2 Logicmaster 90 Serial Version, No Workstation Interface Board If the programmer is equipped with the serial version of Logicmaster 90–70, and does NOT have a Workstation Interface Board, connection must be made via an intermediate RS422/RS485 to RS–232 Converter. If no isolation is required, use GE Fanuc RS–232/RS–422 Converter IC690ACC900A. If isolation is required, use GE Fanuc RS–422 Isolated Repeater/RS–232 Converter IC655CCM590, or an equivalent product.
2 Multidrop Connections Multidrop connections are described in the Series 90–70 Installation and Operation Manual (GFK–0262). Additional instructions are given below. Connection is made between the CPU and the serial port on the Remote I/O Scanner. Terminating the Remote I/O Scanner’s Serial Port The serial port on the Remote I/O Scanner must be terminated if the Remote I/O Scanner will be at the end of a multidrop network.
2 Programmer Connections in a Multidrop Network In a multidrop network, a programmer connected to the CPU can communicate with the Remote I/O Scanner over the serial link, as shown below. A programmer can also be connected directly at the remote drop. However, when the Remote I/O Scanner is part of a multidrop network, its serial port, which is used for connection of the serial link, is not available for direct connection of a programmer.

Chapter 3 3 Remote I/O Scanner Operation section level 1 1 figure bi level 1 table_big level 1 This chapter explains how a Remote I/O Scanner interacts with the modules in its remote drop, how it stores data, and how it exchanges data with a PLC or other type of system host. Overview The Remote I/O Scanner scans I/O modules in its remote drop in the same manner in which a Series 90–70 PLC CPU scans I/O modules in the PLC. Its internal memories store the remote drop’s I/O data.
3 I/O Scan Scanning begins immediately at powerup, unless a fatal diagnostic error occurs within the module. At powerup, all I/O in the remote drop, except those that are presently forced, default to Off. I/O that are forced at the time of powerup start operation in the forced state or value. Run Mode Following a successful powerup, a Remote I/O Scanner goes into Run mode. It remains in Run mode unless a fatal fault or other serious problem occurs.
3 I/O Scanner Memory The Remote I/O Scanner has %I, %AI, %Q, %AQ, and %R internal memories. The following table shows how much memory of each type the Remote I/O Scanner has, and the maximum amount that may be transferred with the host.
3 Data Transfer with the Host Each bus scan, a Remote I/O Scanner exchanges the following data with the host PLC or computer: H H It sends an input message with up to 128 bytes of %I and/or %AI inputs. It receives an output message with up to 128 bytes of %Q and/or %AQ outputs. The exact length and content of these messages is determined by the remote drop I/O map configured for the Remote I/O Scanner. The data from each table (%I, %AI, %Q, and %AQ) must be contiguous.
3 Input Data Sent by the Remote I/O Scanner When the Remote I/O Scanner has its turn on the bus, it sends one input data message containing the latest values for all configured discrete inputs followed by all configured analog inputs. Because they are broadcast (like all Genius inputs), they can be obtained by any Bus Controller on the bus.
3 Outputs from the Host to a Remote Drop Each time the host’s Bus Controller has the bus communications token, it sends any outputs it has received from the CPU to the devices on the bus. Outputs for the Remote I/O Scanner are sent in one output data message, with all configured discrete outputs followed by all configured analog outputs.
3 Configuring Extra References Normally, there are no extra references configured for the Remote I/O Scanner, since that would consume extra references in the host CPU, making them unavailable for other modules. In addition, extra references add to the Genius bus scan time, so they should be avoided if they are not actually needed. However, reserving extra references or leaving vacancies at configuration time is a convenient way to prepare for future additions to a remote drop.
3 Using Option Modules in a Remote Drop PCMs (Programmable Coprocessor Modules), GDS (Graphics Display Coprocessor Modules), and ADS (Alphanumeric Display Coprocessor Modules) can be located in a remote drop. These option modules look at the Remote I/O Scanner as though it were a Series 90–70 PLC CPU.
3 Sending Data from an Option Module to the Host To send data to the host CPU, the option module must place that data into the %I or %AI memory area of the Remote I/O Scanner. The data must be located within the range of %I or %AI memory configured for transfer to the host, and cannot correspond to an input module. It must correspond to a gap in the input portion of the remote drop I/O map.
3 Direct Access to I/O by Option Modules A PCM, GDS, or ADS module in the remote drop can read inputs from, and send outputs to, any I/O module in the drop. This may include modules which do not communicate with the system host at all. It is possible to place I/O modules in a remote drop, and use Logicmaster 90 to assign them references outside the range configured for the Remote I/O Scanner.
Chapter 4 Configuration with Logicmaster 90–70 4 section level 1 1 figure bi level 1 table_big level 1 This chapter explains: H H how to use Logicmaster 90–70 software to configure a Remote I/O Scanner and the modules in a remote drop. See page 55. how to convert Remote Drop configuration folders created with Release 3 Logicmaster software to Release 4 configuration folders. See page 54. The instructions in this chapter are for rev. 4.01 or later of the Logicmaster 90–70 software.
4 Using Release 3 Configuration Files with Release 4 Software With Release 3 of the Logicmaster software, multiple folders were needed for the configuration: one for the PLC, and one for each remote drop. With Release 4 software, all configuration files are contained within the same folder. Instructions to convert existing, operational Release 3 remote drop folders to a Release 4 common folder are summarized below, and explained in detail on the following pages. 1.
4 Configuring a Remote Drop A Remote I/O Scanner must be configured as a device on a Genius bus. If the Bus Controller has not been configured yet, refer to the configuration instructions in the Series 90–70 Genius Bus Controller User’s Manual.
4 Selecting the Bus Address Move the cursor to the Bus Address that will be used by the Remote I/O Scanner and press F8 (Remote). (The Bus Address is the Remote I/O Scanner’s address on the Genius bus; this number is not its DROP ID. See the explanations of Bus Address and Drop ID on the next page if you would like more information.) Next, this catalog list appears: Press the Enter key. The Remote I/O Scanner is now entered at the selected Bus Address.
4 After the configuration is saved, the Remote Drop rack configuration screen appears. The Remote I/O Scanner is located in slot 1. The configuration screen shows the rack and slot location of the Bus Controller, and the Bus Address, Remote Drop rack, and Drop ID of the Remote I/O Scanner.
4 With the REMSCAN slot still selected, press F10 (zoom) to configure the Remote I/O Scanner. The first configuration screen appears. Auto I/O Map is ON The next available Reference Addresses within the PLC configuration have been automatically calculated and assigned. The information on this screen and entries you can make are described below. Drop ID The Remote I/O Scanner’s Drop ID also appears on this screen. It can be edited here, if necessary.
4 I/O Map The I/O map represents the boundaries of the I/O references assigned to the remote drop which will be scanned by the central PLC. Before any modules are configured, the I/O map begins at the next available reference in each data type, based on the PLC configuration, and each reference type has a length of 0. You can change the reference starting addresses and enter lengths manually, or you can use automatic I/O mapping. The best method to use will depend on your application.
4 Using Auto I/O Map Use Auto I/O Map if you want to use the software’s automatic I/O mapping feature. With Auto I/O Map, the first I/O module of a given data type is assigned the same offset as the offset of the I/O map. Auto I/O Map automatically supplies lengths for the I/O map by incrementing the map as I/O modules are configured. In addition, if you change the reference address of the first module configured for a data type, Auto I/O Map changes the beginning address of the I/O map to match it.
4 presently–unavailable modules. Alternatively, you can could configure the existing equipment with Auto I/O Map ON, then turn it OFF and edit the length fields to provide space for the future modules, You need to plan this early; if you don’t leave enough room for future modules, extensive reconfiguration may be required later on. If some I/O will not be scanned by the central PLC: I/Odata that is assigned to references outside the I/O map will not be exchanged with the PLC during system operation.
4 Press the Page Down key to display the second configuration screen for the Remote I/OScanner. The selections you can make on this screen are explained below. Genius Interface Entries Several of the Genius entries relate to both redundancy and CPU redundancy. These features are described in detail in the Bus Controller User’s Manual.
4 BSM Present In a dual bus system, if the Remote Drop will be located downsteam of another device that controls bus switching (either a Bus Switching Module or another Remote I/O Scanner), set this entry to YES. Timeout Sec If either of the previous two entries is YES, and the total bus scan time is expected to exceed 100mS, set this entry to 10. This entry is equivalent to the Switch Time entry made for the Bus Controller. It is the amount of time that will be allowed for switching on a dual bus.
4 during the Store operation. XXX stands for a Drop ID of 016 to 254. This can be changed on the SNP ID screen. The last three digits of the SNP ID refer to the Remote I/OScanner’s Drop ID and cannot be changed directly. Sweep Control Entries Most applications will use the default programmer and communications windows times. Prog Window Programmer window time. The range is 0 to 255 milliseconds. 10mS is the default. Comm Window Communications window time. The range is 0 to 255 milliseconds.
4 Configure the Modules in the Remote Drop Configuring modules in a Remote Drop is the the same as configuring modules in the central PLC. First, select a slot: Use the function keys to select a module type. When the catalog number screen appears, you can either enter a catalog number or use the function keys again to display a list of appropriate modules with their catalog numbers.
4 Enabled/Disabled,Transition Positive/Negative, and Input Filter Time. Configure such selectable features as appropriate for your application. Note Such module features can only be selected using the Logicmaster 90–70 software. If a remote drop is configured (or reconfigured) using a Genius Hand–held Monitor, the I/O boards in the remote drop will operate in default mode only––optional features cannot be selected.
4 Entering Additional Modules Configure the rest of the modules in the Remote Drop in the same way. You can also copy, delete, and undelete module configurations. Modules of the same type are automatically given the next Reference Address that is available in the remote drop. Reference Address increments automatically, based on limits for the remote drop. You can use this address, or change it.
4 Completing the Remote Drop Configuration For the example configuration, the Remote Drop rack display looks like this: The I/O map and references for each module are displayed. When you are finished configuring the modules in the Remote Drop, press ESC.
4 Reference Overlaps If you have entered a conflicting reference address, the following warning appears: Overlapping addresses Overlapping references are permitted in %Q and %AQ. Overlapping references in %I and %AI are not permitted; such a configuration is not valid. With the next press of any key after the message appears, the configuration is saved to disk. Return to the Remote Drop configuration screens and remove the conflict.
4 Changing Reference Addresses and Lengths The I/O map shows the beginning Reference Address or Length assigned to the Remote I/O Scanner for %I, %Q, %AI, and %AQ data. You can change any reference address or length in the I/O map. If you change a reference address after entering modules of that data type in the Remote Drop, you can have the software automatically reassign their reference addresses to begin at the new I/O map reference address by responding “Y” at the prompt.
4 Displaying Configured References If you want to display references configured for the PLC or a Remote Drop, use Reference View. Reference View shows any reference conflicts that have been created. Viewing PLC References To see the references in the Remote I/O Scanner’s I/O Map together with the rest of the PLC configuration, select Reference View (shift–F3) from the rack or bus screen. The illustrations below show Reference Views for a system with three Remote I/O Scanners.
4 Viewing Remote Drop References The Remote Drop Reference View screens show references assigned to individual modules in a Remote Drop, and indicates reference overlaps as well as modules that are outside the Remote I/O Scanners’s I/O Map. You can reach the Remote Drop Reference View Screens by selecting REF VU (shift–F3) while in a Remote Drop configuration, or by selecting Expand (F1) from any PLC Reference View screen while the Remote I/O Scanner entry is highlighted.
4 Copying, Deleting, and Undeleting Individual modules in the Remote Drop configuration can be copied, deleted, and undeleted in the same way as modules in the PLC configuration. You can also copy, delete, and undelete Remote I/O Scanners and their remote drop configuration files from the bus level. (A Remote I/O Scanner cannot be copied, deleted, or undeleted from within the Remote Drop rack configuration.
4 Selecting an Existing Configuration File The Configuration Select feature can be used to display and select the available configuration files. To use Configuration Select, use the CFGSEL (shift–F6) key from any rack, bus, or Remote Drop rack screen. You can enter the name of the file (for a Remote Drop, use the format dropXXX, as discussed above), or select it from the list on the screen. When you select a configuration file by pressing the Enter key, that configuration appears on your screen.
4 Storing the Configuration In addition to storing the central PLC configuration, a remote drop configuration created with Logicmaster 90 software must be stored to each Remote I/O Scanner as described below. Storing the Configuration to the PLC Use the Utility functions to store the program folder to the PLC as described in the Logicmaster 90–70 User’s Manual. Storing a Remote Drop Configuration Follow the steps below to store a remote drop configuration to a Remote I/O Scanner. 1. 2. 3. 4.
Chapter 5 5 Logicmaster 90 Operation with a Remote section level 1 1 Drop figure bi level 1 table_big level 1 This chapter explain how to set up a Logicmaster 90 programmer to communicate with a remote drop. It also describes functional differences in Logicmaster 90 when it is communicating with a remote drop. Overview A Logicmaster 90–70 programmer can be used to configure and monitor the operation of a remote drop. Either serial or parallel Logicmaster can be used.
5 Setting Up Programmer Communications with a Remote Drop To set up the programmer for remote drop communications, follow these steps: 1. Go to the LM90–70 Programmer Setup Menu: 2. In the Setup Menu, choose F3 ..... Select SNP/Parallel Connections The following screen appears: This screen lists the available devices in the network. Each PLC or remote drop on the network should be included here once its SNP ID has been configured. 3.
5 Status Display for a Remote Drop When the programmer is communicating with the PLC CPU, the status lines at the bottom of the screen display information about the CPU. When communicating with a remote drop, the status lines display information about the Remote I/O Scanner. The first field identifies the SNP ID for the remote drop. The second shows whether the Remote I/O Scanner is presently running, and scanning the I/O modules in the remote drop.
5 Logicmaster 90 Software, Programmer Differences for a Remote Drop When used with a remote drop, the features of the programmer are similar to the features used with a Series 90–70 PLC. Features Not Used for a Remote Drop Certain programmer features are not used for a remote drop.
5 Programming Software: Differences for a Remote Drop The features of the Logicmaster 90–70 software have the differences described below when used with the remote drop (versus normal PLC operation). Feature From Remote Drop LM90–70 Folder (Attached to Remote I/O Scanner) ProgramDisplay/Edit When communicating directly with a remote drop, programmer is NOT EQUAL to PLC. Real–time updates do not occur for the display, and online editing changes cannot occur.
Chapter 6 6 Remote Drop Configuration with a Hand–held Monitor section level 1 1 figure bi level 1 table_big level 1 This chapter explains how to configure a Remote I/O Scanner and the I/O modules in a remote drop using a Genius Hand–held Monitor. HHM version 4.0 (IC660HHM501G) or later is required. If the remote drop includes any Analog Expander Modules, Logicmaster 90 must be used for configuration; do not use a Hand–held Monitor.
6 Overview A Hand–held Monitor provides automatic configuration of I/O references for a remote drop. The Hand–held Monitor automatically assigns references for the presently–installed Series 90–70 I/O modules only. It does so in ascending order, starting with the slot next to the Remote I/O Scanner. When a remote drop is configured with a HHM, all I/O modules will operate in default mode; module options can only be configured with the Logicmaster 90–70 software.
6 When configured with a Hand–held Monitor, the Remote I/O Scanner automatically assigns I/O references to the modules in the remote drop starting with the reference(s) assigned by the user via the Program Block ID screens. The left–most module of each type (%I, %Q, %AI, or %AQ) in the rack receives the first available reference of the appropriate type. The HHM then incrementally assigns references according to the types and locations of modules in the rack, in left–to–right order.
6 Set Up the Hand–held Monitor 1. If the remote drop is connected to an operating bus, the Hand–held Monitor must be the ONLY Hand–held Monitor plugged into any device on the bus. If the remote drop that is NOT connected to a properly–terminated Genius bus, install a 150Ω terminating resistor across the upper Serial 1 and Serial 2 terminals on the Remote I/O Scanner.
6 Display the Configuration Main Menu To begin remote drop configuration, select F3 (Configuration). The configuration Main Menu appears. F1:PROG BLOCK ID F2:CONFIG BLOCK F3:COPY CONFIG F4: From this menu, select Program Block ID (F1) to complete the basic remote drop configuration screens. After completing these screens, press F2 (Configure Block) to complete the Genius configuration screens, or to display information about the I/O modules in the remote drop.
6 Select the Device Number The first step in configuring any device on a Genius bus is to assign its Device Number (bus address). This is a number from 0 to 31 representing the serial bus address of the device. There are 32 available addresses on a bus. One is needed for the Hand–held Monitor; typically this is Device Number 0. Another is needed for the Bus Controller. Typically, this is Device Number 31. A Remote I/O Scanner is usually assigned a Device Number from 1 to 30.
6 Select a Series Six or Series Five PLC Reference Address If the host is a Series Six PLC or Series Five PLC, an I/O or register reference address must be assigned to the Remote I/O Scanner. This is done on the Program Block ID screen. It is also necessary to configure Series 90–70 data types and lengths, as described later in this chapter. HHM Display (Series Six/Series Five Host CPU Mode) PROG BLOCK ID I/O ?– ?? BLOCK NO. ? ref blk nxt Configuration Steps 1.
6 Select the Baud Rate Genius bus communications can occur at any of four baud rates: 153.6 Kbaud standard, 153.6 Kbaud extended, 76.8 Kbaud, or 38.4 Kbaud. The default is 153.6 K baud (standard). The Genius I/O System User’s Manual gives guidelines for baud rate selection. Each device’s communications baud rate must be the same as that used by all other devices on the bus, or the bus will not operate. HHM Display SELECT BAUD RATE ACTIVE=153.6K ST PROG =153.6K ST tgl entr nxt Configuration Steps 90 1.
6 Select Series 90–70 Data Lengths The Remote I/O Scanner must be assigned a starting address and length for one or more of the following data types that will be used by I/O modules in its remote drop: %I the discrete input table %Q the discrete output table %AI the analog input table %AQ the analog output table These entries are required whether or not the host CPU is a Series 90–70 PLC.
6 The next screen that appears is used to assign the data types and lengths. HHM Display PROG REMOTE MAP %I ____ LENGTH(PTS) ____ tgl ref send nxt Configuration Steps 1. To select a data type, press F1 (tgl). In sequence, line 2 will display: %I (discrete input bits), %Q, (discrete output bits), %AI (analog input words), %AQ (analog output words). Pressing F1 (tgl) a fourth time displays the Drop ID configuration screen. 2.
6 Select the Remote Drop ID The same configuration screen is used to assign a Remote Drop ID. A Remote Drop ID is a number between 16 and 254 that allows the Remote I/O Scanner to communicate with serial Logicmaster 90–70 for multidrop programming. The ID distinguishes one remote drop from another. A valid entry must be made on this screen even if the host type is not a Series 90–70 PLC.
6 Display I/O Modules in Remote Drop When you enter the Configure Block screens, the Hand held–Monitor displays the configuration of the first I/O module in the remote drop. An example is shown below. This is a read–only function; I/O module configuration cannot be changed with the Hand–held Monitor.
6 Select Genius Bus Redundancy After the last module display screen, the Hand–held Monitor displays the redundancy configuration screens for the Remote I/O Scanner. The first of these indicates whether or not the Remote I/O Scanner will be located on a dual bus or bus stub. The default configuration for BSM Present is NO.
6 Select CPU Redundancy If the remote drop will be used on the same bus with two controllers (PLCs or host computers), each of which will send it outputs, the Remote I/O Scanner must be set up for CPU Redundancy. For a new Remote I/O Scanner as shipped from the factory, this feature is not enabled. Remote I/O Scanner version IC697BEM733B or later is required to use this feature. The two types of CPU Redundancy, Hot Standby and Duplex, are described below.
6 Select Configuration Protection This feature can be used to protect the remote drop configuration, preventing changes from the CPU or Hand–held Monitor. It can only be selected from a Hand–held Monitor. To make subsequent changes, protection must be removed again using a Hand–held Monitor. Before the remote drop is used, its configuration should be protected. After a Remote I/O Scanner has been configured from Logicmaster 90–70, its configuration is automatically protected.
Chapter 7 7 Monitoring and Controlling Remote Drop Data section level 1 1 figure bi level 1 table_big level 1 This chapter explains how to monitor or control remote drop I/O data using Genius Hand–held Monitor or a programmer. Overview There are three ways to manipulate I/O data in a remote drop: A. by forcing an input or output to assume a desired state or value which will be stored in the Remote I/O Scanner’s EEPROM memory.
7 Forcing Circuits Forcing an I/O circuit from a Hand–held Monitor causes the circuit to assume a selected state (for discrete circuits) or value (for analog circuits). The forced state/value is also stored in the Remote I/O Scanner’s EEPROM memory, and will survive power failure. Because the forced state or value is stored in EEPROM, forcing is the only method of manipulating I/O circuits that guarantees a fixed output/input state.
7 Overriding I/O Circuits Overriding an I/O circuit means changing its state or value in the PLC’s Override Tables. Overrides must be done from the PLC, with the remote drop online. Results can be viewed on the programmer screen. It cannot be done at the remote drop. The override data is stored in the PLC, and survives loss of power in the PLC. However, if power is lost at the PLC but not at the remote drop, the Remote I/O Scanner operates as it normally does if CPU communications are lost.
7 Monitoring/Controlling I/O Data: Genius Hand–held Monitor A Genius Hand–held Monitor can be used to display current I/O states and diagnostics, and to force and unforce individual I/O points. From the HHM main menu, select either F1 (Monitor Block) or F2 (Monitor/Control Reference). Both functions access the same set of display screens for the Remote I/O Scanner. The first screen that appears is the Monitor screen for the module with the first %I reference. MNTR 1 143#0.
7 Finding the Circuit’s Series 90 Reference You can use the circuit number and starting reference for the module to find the exact Series 90–70 I/O reference of the circuit. For example, suppose the first two HHM lines show the following: MNTR 3 143#0.3 %I 33 STS 0 FAULT > ref force diag The Series 90–70 I/O reference for the circuit is one less than the sum of the two numbers on the right–hand side of the HHM screen. Here: 3 + 33 – 1 = 35 In this example, the circuit being monitored is %I0035.
7 Multiple Faults for the Same Circuit The Remote I/O Scanner stores faults (up to 64) in time sequence, not reference sequence. To see whether there are additional faults on the same reference, use the F4 (nxt) key to go through the fault screens. Watch the reference identification on line 2 for the specific circuit you are interested in. Returning to the Monitor Screen Press F1 (mon) to return to the Monitor screen you started from. For more information about diagnostics, see chapter 10.
7 Forcing an Analog Circuit If the circuit to be forced is an analog circuit, its current value appears on line 3 of the Monitor screen. MNTR 3 143#0.3 %AI 1 STS –22138 > ref force diag a Circuit value MNTR 3 143#0.3 %AI 1 FRC –22138 > ref force diag a Circuit is not forced Pressing F3 (force) displays: Press F2 (force) to enter a forced value for the circuit. The screen displays: FORCE TO: ______ chng entr Press F2 (chng). Enter the value, then press F3 (entr). The forced value appears on line 3.
7 Displaying Other Circuits In monitor mode, the HHM will step through I/O modules in the following sequence: 1. %I, all references used 2. %AI, all references used 3. %Q, all references used 4. %AQ, all references used To display additional circuits within the currently–selected memory type, press the F1 (>) key. The HHM will step through each available circuit. To jump directly to a particular device, memory type, or address, press F2 (ref). This screen appears, to enter the desired information.
7 Monitoring/Controlling I/O Data: Logicmaster 90–70 Logicmaster 90–70 can be used to monitor I/O in the remote drop, either from the PLC I/O Tables or from the Remote I/O Scanner’s internal I/O tables. Reference Tables Display from the PLC When the system is in operation and the remote drop is communicating with the PLC via a Genius bus, the I/O in the remote drop can be monitored as part of the complete system.
7 Reference Tables Display for the Remote I/O Scanner When the programmer communicates directly with the remote drop, the Logicmaster reference tables display the Remote I/O Scanner’s internal %I, %Q, %AI, %AQ, %R, %S, %SA, %SB, and %SC memories. I/O data in the Remote I/O Scanner’s %I, %AI. %Q, and %AQ tables corresponds to discrete and analog I/O cards in the remote drop, and/or data being manipulated by option modules. Any other memory locations in these tables are zero.
7 Monitoring/Controlling I/O Data: Series Six PLC or Series Five PLC For a Series Six or Series Five PLC, I/O data for a remote drop may be configured to use either I/O or register memory. To utilize the data correctly, it is necessary to know the position of each module in the rack, and the amount of input and output data it has. Data lengths are equal to the amounts configured for %I, %AI, %Q, and %AQ. For discrete data, 16 points = 16 I/O references or 1 register.
7 Analog values can be displayed in decimal, signed decimal, or hex using the programmer function keys.
7 Remote Drop Data in Register Memory If Series Six or Series Five register memory is used for remote drop data, an amount is required that is equal to the total number of bytes of input data PLUS output data. The data is stored beginning at the assigned register reference. The sequence is: discrete inputs, then analog inputs, then discrete outputs, and analog outputs last. Data lengths are equal to the amounts of %I, %AI, %Q, and %AQ configured for the Remote I/OScanner.
7 Monitoring/Controlling I/O Data: Computer To utilize the Remote I/O Scanner’s I/O data correctly, a computer must know the sequence of modules in the rack, and the amount of input and output data each has. For the PCIM, QBIM, and other GENI–based interfaces, the input and output data will occupy the Device Input and Output Tables at the segments associated with the Device Number of the Remote I/O Scanner.
Chapter 8 Diagnostics and Fault Clearing 8 section level 1 1 figure bi level 1 table_big level 1 This chapter describes the diagnostics capabilities of the Remote I/O Scanner, and explains how faults on a remote drop can be cleared from a Hand–held Monitor or programmer. Overview The Remote I/O Scanner receives all standard Series 90–70 board–level diagnostics from modules in the remote drop. These faults can be viewed and cleared from a programmer fault table, or using a Genius Hand–held Monitor.
8 Display and Clear Faults from a Genius Hand–held Monitor A Genius Hand–held Monitor can display faults from a remote drop while attached anywhere on the Genius bus. Fault status is available from the HHM’s Block/Bus Status screen, or the Monitor Block screen. Fault Information on the Block/Bus Status Screen The fault status of any remote drop on a Genius bus can be displayed from the Hand–held Monitor’s Block/Bus Status screen. 1. From the HHM Main Menu, select F2 (analyze).
8 Displaying Faults from the Monitor Block Screens From the HHM main menu, select either F1 (Monitor Block) or F2 (Monitor/Control Reference). Both functions access the same set of display screens for the Remote I/O Scanner. MNTR 1 143#0.2 %I 1 STS 0 > ref force diag From any Monitor screen, press F4 (diag) to display diagnostics for the remote drop. The Hand–held Monitor displays the first fault it encounters. For example: DIAG 143#0.
8 Display and Clear Faults from Logicmaster 90–70 The content of the PLC and I/O Fault Table displays depends on whether the programmer is communicating with the PLC or a remote drop. I/O Fault Table at the PLC The content of the fault display at the PLC depends on the revision level of the Bus Controller. With a Bus Controller that is version 4.
8 I/O Fault Table at the Remote I/O Scanner If the programmer is communicating with a remote drop and in on–line mode, the I/O Fault Table shows the remote drop rack and slot locations of the module where the fault occurred, and a description of the fault.
8 PLC Fault Table at the Series 90–70 PLC If the programmer is communicating with a Series 90–70 PLC and a remote drop fault occurs, the PLC Fault Table shows the Drop ID and the rack and slot within the remote drop where the fault has occurred: 33#0.1 Drop ID Rack Slot Slot 1 is occupied by the Remote I/O Scanner.
8 PLC Fault Table at the Remote I/O Scanner If the programmer is communicating with a remote drop and in on–line mode, the PLC Fault Table shows the remote drop rack and slot locations of the module where the fault occurred, and a description of the fault. Faults on option modules (such as the PCM) are listed in the Remote I/O Scanner’s PLC Fault Table. Faults on I/O modules are listed in the I/O Fault Table.
8 Status References Status references in the Remote I/O Scanner are assigned to %S, %SA, %SB, and %SC memory. These references have the same definitions as the status references for the Series 90–70 PLC, although not all are meaningful for a Remote I/O Scanner. They can be monitored using the reference tables function of Logicmaster 90 with the programmer communicating with the remote drop.
8 Display and Clear Faults from Logicmaster 5 or Logicmaster 6 If the host CPU is a Series Five or Series Six PLC, faults from a remote drop are displayed in the Genius Fault Table. A Logicmaster 6 fault table is illustrated below. The Logicmaster 5 fault table is similar. Faults from remote drops are identified as GENA faults. The GENA is the component within the Remote I/O Scanner that handles the Genius bus interface. TOTAL FAULTS: 0000 TOP FAULT DISPLAYED:0000 FAULT DISPLAYED: B/C ADDR.
Chapter 9 9 Remote I/O Scanner Datagrams section level 1 1 figure bi level 1 table_big level 1 This chapter lists datagrams that can be sent to a Remote I/O Scanner module, and shows the format of the Read Map, Write Map, and Read Map Reply Datagrams. Datagrams cannot be sent to individual I/O modules in a remote drop. It also shows the format of Report Fault datagrams that are sent by the Remote I/O Scanner.
9 Datagram Types The table below shows the types of device that can send each datagram, and the resulting action taken by the Remote I/O Scanner.
9 Read Map Subfunction Code: 2A hex This datagram is used to read the Series 90–70 I/O references assigned to a Remote I/OScanner, and its Remote Drop ID. Data Field Format: none Read Map Reply Subfunction Code: 2B hex A Remote I/O Scanner sends this reply datagram after receiving a Read Map datagram. It contains the Series 90–70 I/O references assigned to the Remote I/O Scanner, and its Remote Drop ID. It provides no information about the I/O assignments of individual I/O modules in the remote drop.
9 Report Fault Datagram Format The format of Report Fault datagrams sent by a Remote I/O Scanner is shown below. The Series 90–70 Bus Controller interprets this information automatically; no datagram programming is required. If the host is a Series Six or Series Five PLC, this information is ignored. If the host is a computer, this information can be retrieved from the unsolicited datagram queue, and interpreted as needed for the application.
9 Fault Byte 3 byte 2 7 6 5 4 3 2 1 0 Fault record number (always 0) Number of fault records Fault Bytes 4 and 5 Fault bytes 4 and 5 (bytes 3 and 4 of the datagram) identify the reference offset (within the Remote I/O Scanner itself) assigned to the faulted module. This is an internal reference, not a Series 90–70 reference.
Appendix A Estimating the Number of Remote Drops for a Bus A section level 1 1 figure_ap level 1 table_ap level 1 The number of remote drops that can be installed on a bus depends on the baud rate and the total number of I/O points in the remote drops. Only twenty fully–loaded remote drops are supported on a single bus that operates at 153.6 Kbaud (see chapter 1). If remote drops are not fully–loaded, more may be used.
Appendix B Finding the I/O Configuration Data Total for a Remote Drop section level 1 1 figure_ap level 1 table_ap level 1 B The maximum amount of I/O configuration data for a remote drop is 4500 bytes.
B 2. Add the contribution of each I/O module in the remote drop. For discrete input modules, the contribution is either 36 bytes for modules with catalog numbers IC697MDL2nn (for example, IC697MDL241) or 42 bytes for modules with catalog numbers IC697MDL6nn. 3. 4. Include 50 bytes as the contribution of the Remote I/O Scanner itself. Option (PCM, GDS, ADS) modules do not have I/O configuration data, so they are not included in the calculation.
Appendix C Logicmaster 90–70, Release 3: Series 90–70 PLC Configuration for Remote Drops section level 1 1 figure_ap level 1 table_ap level 1 C This appendix explains how to include a Remote I/O Scanner in the configuration of a Series 90–70 PLC using Release 3 of the Logicmaster 90–70 software. t Overview If you are using Release 3 of the Logicmaster 90–70 software, any Series 90–70 PLC on a Genius bus with a Remote I/O Scanner must be configured as described in this appendix.
C Step 1: Create or Select a PLC Program Folder To begin configuring a remote drop, go to the Program Folder screen and select or create the PLC program folder. If the Bus Controller has not already been configured, continue at step 2. If you are adding a Remote I/O Scanner to a bus that has already been configured, go to step 3 now. Step 2: Add the Remote I/O Scanner to the Genius Bus Display the configuration screen for the rack where the Bus Controller is located.
C With the Bus Controller selected in the rack display, zoom into the Bus Controller to display the bus configuration screen. In this example, the bus configuration screen shows the bus controller being configured at its default location––bus address 31. To select a bus address for the Remote I/O Scanner, move the cursor to the desired number and press F8 (Remote).
C The central CPU rack display returns. Press F10 (zoom) to display the remote drop rack configuration screen.
C Step 3: Configure the Remote I/O Scanner On this screen, enter the Remote Drop ID and the I/O map to be used for the Remote I/OScanner. Bus Adr 29 Input Def : Out Rnable: OFF YES Entering the Scanner’s Remote Drop ID The Scanner’s Remote Drop ID is its remote drop communications ID. The range of possible IDs is 16–254. If this is the first remote drop to be configured, the number 16 should appear in the REMOTE DROP ID: field.
C Assigning I/O References for the Remote I/O Scanner The discrete and analog I/O references that will be used by the Remote I/O Scanner must be configured. A starting address and length must be specified for at least one of the following: H H H H %I the discrete input table %Q the discrete output table %AI the analog input table %AQ the analog output table For each table used, a contiguous block of references must be assigned.
C Input Default/Out Enable The two final fields specify how input and output conditions will be handled following loss of communications, and whether outputs will be sent automatically after powerup. Input Default: Specifies the state presented to the PLC for all %I and %AI references in the remote drop, in the event communications with the Remote I/O Scanner are lost. The options are to default off or to hold last state.
C Using the Copy Configuration Feature Once a Remote I/O Scanner has been entered into the PLC configuration, it can be copied to any other location on the bus. With the cursor at the module to be copied, press the Copy key. Move the cursor to the intended location for the copy and press the Enter key. When the configuration of a Remote I/O Scanner is copied, the Logicmaster 90–70 software automatically increments the Remote Drop ID and the Reference Addresses for the copy to the next ones available.
Appendix D Logicmaster 90–70, Release 3: Remote Drop Configuration Instructions D section level 1 1 figure_ap level 1 table_ap level 1 This appendix explains how to configure a remote drop using Release 3 of the Logicmaster 90–70 software. Individual remote drop configuration files that have been created using Logicmaster 90–70 Release 3 software can be incorporated into a common folder using Release 4 software.
D Remote Drop Configuration Summary Configuring a remote drop with Logicmaster 90–70 is similar to configuring a rack with a CPU and I/O modules. The configuration steps are: 1. Select or create the folder for the remote drop configuration. For a Series 90–70 PLC host, this should be located in the central PLC’s drawer, with the name of the remote drop _DROPxxx, where xxx is the remote drop ID (016–254). 2. Configure the Remote I/O Scanner module in rack 0, slot 1.
D Step 1: Create a Folder To begin configuring a remote drop, go to the Program Folder screen and create a new folder for its configuration. For a Series 90–70 PLC, you should create the central PLC’s program folder, even if the remote I/O is to be installed first (just configure the folder off–line). By doing the folders in this order (PLC folder first), all reference conflicts will be avoided. Select the central PLC drawer.
D Step 2: Configure the Remote I/O Scanner Display the configuration screen for Rack 0, which is where the Remote I/O Scanner is installed. The Remote I/O Scanner is installed in slot 1 of the rack; however, as the configuration screen shows, this is the slot normally assigned to a CPU. The CPU module must be replaced in order to create a remote drop folder. In the Rack 0 display, zoom (F10) into the CPU slot, and press the F2 (Remote) key. A module description screen appears.
D Entering the Scanner’s Remote Drop ID The Scanner’s Remote Drop ID is its remote drop communications ID. The range of possible IDs is 16–254 The default is 16, which should initially appear in the REMOTE DROP ID: field. Each remote drop in a serial communications network must have a unique Remote Drop ID. When stored from Logicmaster 90–70, the default SNP ID will be DROPxxx, where xxx is the Remote ID assigned from the screen illustrated above.
D Series Six or Series Five PLC Reference For a Series Six or Series Five PLC system that uses I/O table references, a previously–unconfigured Remote I/O Scanner will accept a reference entered here. It will be the reference for the first data type (in the sequence listed above) for which you enter a non–zero length. For example, if the remote drop has only analog input and output boards, the data lengths for %I and %Q would be 0. You would enter a data length for %AI and %AQ.
D Definitions of Communications and Operating Parameters The following table summarizes the Genius configuration parameters, communications port configuration parameters, and sweep control parameters for a Remote I/O Scanner. Genius Parameters SNP Communications Port Parameters Sweep Control Parameters Parameter Description Default Choices Baud Rate ] Genius bus baud rate 153.6 Kbaud standard 153.6 Kbaud standard, 153.6 Kbaud extended, 78.8 Kbaud, 38.
D Step 3: Configure the Modules in the Remote Drop In addition to configuring the Remote I/O Scanner, the Logicmaster 90–70 software is used to configure the modules in the remote drop, the rack type, and the Power Supply type. Configuration steps are the same as described in the Logicmaster 90–70 Software User’s Manual. When configuring modules in the remote drop, do not exceed the maximum configuration limits listed on the next page.
D Conversely, it is possible that a PCM, GDS, or ADS module contains data which it wishes to pass to the host, or that it requires data to be supplied by the host. To pass data to the host, some %I or %AI memory which is not used by I/O modules must be included in the remote drop I/O map; the PCM, GDS or ADS will then be able to deposit data there, and that data will automatically be transported to the host. To receive data from the host, allocate some %Q or %AQ references within the remote drop I/O map.
D Step 4: Store the Configuration to the Remote Drop After creating or editing the configuration of a remote drop, the configuration can either be saved to disk, or stored to the remote drop. Caution Be sure the configuration does not contain too many option modules, or too much I/O configuration data.
