2–14 Selecting Your Hardware Components Example — Worksheet for Selecting a 1746 Power Supply If you have a multiple chassis system, make copies of the Power Supply Worksheet found on page E-1. For a detailed list of device load currents, refer to the SLC 500 Modular Chassis and Power Supplies, Publication Number 1746-2. Procedure 1. For each slot of the chassis that contains a module, list the slot number, the catalog number of the module, and its 5V and 24V maximum currents.
Selecting Your Hardware Components 2–15 Selecting Enclosures The enclosure protects the equipment from atmospheric contamination. Standards established by the National Electrical Manufacturer’s Association (NEMA) define enclosure types, based on the degree of protection an enclosure will provide. Use a fan to circulate the air of sealed enclosures that use convection cooling to dissipate heat. Select a NEMA-rated enclosure that suits your application and environment.
2–16 Selecting Your Hardware Components DH-485 Interface Converter For communication, use an RS-232/DH-485 Interface Convertor (Catalog Number 1747-PIC) between the computer and SLC controller. The converter includes a 279.4 mm (11 in.) ribbon cable, already attached to the converter, for connection to the computer serial port and a Catalog Number 1746-C10 cable for connection to the controller. If you are using an SLC 5/03, SLC 5/04, or SLC 5/05 processor, you do not need the 1747-PIC.
Selecting Your Hardware Components 2–17 A configurable communications port on the interface supports RS-485 and RS-232. Use DH-485 to communicate point-to-point with the SLC processor or over the network via Catalog Number 1747-AIC Isolated Link Couplers. The point-to-point connection allows for faster communication throughput and less DH-485 network loading.
2–18 Selecting Your Hardware Components Selecting a Memory Module for the SLC 5/01 and SLC 5/02 Processors You can plug these optional EEPROM (Electrically Erasable Programmable Read Only Memory) and UVPROM (UV-erasable PROM) memory modules into the SLC 500 controller.
Selecting Your Hardware Components ! 2–19 ATTENTION: Make sure the adapter is inserted properly or damage could result. The following table lists the types of memory modules that are available for the SLC 5/01 and SLC 5/02 processors. Also listed are the manufacturer part numbers for determining compatibility with an external PROM programmer.
2–20 Selecting Your Hardware Components Selecting a Memory Module for SLC 5/03, SLC 5/04, and SLC 5/05 Processors The memory module for the SLC 5/03, SLC 5/04, and SLC 5/05 processors is called Flash EPROM (Flash Erasable Programmable Read Only Memory). Flash EPROMs combine the programming versatility of EEPROMs with the security precautions of UVPROMs. This means that you have the option of leaving your EPROM programs write protected or unprotected.
Selecting Your Hardware Components EEPROM Burning Options 2–21 You can burn a program into an EEPROM memory module using a processor that is the same or different from the one used to run the program. When burning EEPROMs, keep the following conditions in mind: • The program size cannot exceed the processor memory size. For instance, an SLC 5/01 1K processor can burn an EEPROM for a SLC 5/01 4K processor as long as the program does not exceed 1K.
2–22 Selecting Your Hardware Components Selecting Isolation Transformers If there is high frequency conducted noise in or around your distribution equipment, we recommend the use of an isolation transformer in the AC line to the power supply. This type of transformer provides isolation from your power distribution system and is often used as a “step down” transformer to reduce line voltage. Any transformer used with the controller must have a sufficient power rating for its load.
Selecting Your Hardware Components Special Considerations 2–23 The recommendations given previously provide favorable operating conditions for most controller installations. Your application may involve one or more of the following adverse conditions. Additional measures can be taken to minimize the effect of these conditions.
2–24 Selecting Your Hardware Components Selecting Surge Suppressors Most output modules have built-in surge suppression to reduce the effects of high voltage transients.
Selecting Your Hardware Components ! 2–25 ATTENTION: Damage could occur to SLC 500 triac outputs if you use suppressors having RC networks. Allen-Bradley AC surge suppressors not recommended for use with triacs include Catalog Numbers 199-FSMA1, 199-FSMA2, 1401-N10, and 700-N24. Allen-Bradley surge suppressors recommended for use with Allen-Bradley relays, contactors, and starters are shown in the table below.
2–26 Selecting Your Hardware Components Selecting Contact Protection Inductive load devices such as motor starters and solenoids may require the use of some type of surge suppression to protect the controller output contacts. Switching inductive loads without surge suppression can significantly reduce the lifetime of relay contacts. The figure below shows the use of surge suppression devices.
Selecting Your Hardware Components 2–27 Transistor Output Transient Pulses This section applies to the following SLC 500 fixed I/O processors and SLC 500 I/O modules that have transistor outputs.
2–28 Selecting Your Hardware Components To reduce the possibility of inadvertent operation of devices connected to transistor outputs, adhere to the following guidelines: • Either ensure that any programmable device connected to the transistor output is programmed to ignore all output signals until after the transient pulse has ended, • or add an external resistor in parallel to the load to increase the on-state load current.
Chapter 3 System Installation Recommendations To help you install the SLC 500 programmable controller as safely and securely as possible, we have set up a few specific recommendations for you to follow. For general installation guidelines, also refer to the requirements specific to your region. • Europe: Reference the standards found in EN 60204 and your national regulations. • United States: Refer to article 70E of the National Fire Protection Association (NFPA).
3–2 System Installation Recommendations Spacing Your Controllers The figure below depicts acceptable layouts. Follow the recommended minimum spacing to allow for convection cooling within the enclosure. Cooling air in the enclosure must be kept within a range of 0° C to +60° C (32° F to +140° F). Important: Be careful of metal chips when drilling mounting holes for the controllers. Do not drill holes above a mounted SLC 500 controller.
System Installation Recommendations Preventing Excessive Heat 3–3 For most applications, normal convection cooling will keep the adapter components within the specified operating range of 0° C to +60° C (+32° F to +140° F). Proper spacing of components within the enclosure is usually sufficient for heat dissipation. In some applications, a substantial amount of heat is produced by other equipment inside or outside the enclosure.
3–4 System Installation Recommendations ! ATTENTION: The 1746 chassis, the enclosure, and other control devices must be properly grounded. All applicable codes and ordinances must be observed when wiring the adapter system. Ground connections should run from the chassis and power supply on each adapter and expansion unit to the ground bus. Exact connections will differ between applications. Europe: Reference EN 60204 for safety information on grounding.
System Installation Recommendations 3–5 Special Grounding Considerations for DC Applications using 1746-P3 ! ATTENTION: Any voltage applied to the 1746-P3 DC NEUT terminal will be present at the SLC logic ground and the processor DH-485 port. To prevent unwanted potentials across the logic ground of the controller and/or damage to the SLC chassis, the DC NEUTRAL of the external DC power source must be either isolated from the SLC chassis ground, or connected to earth ground.
3–6 System Installation Recommendations Modification to the SLC 500 Chassis SLC 500 chassis (1746-A4, -A7, -A10, and -A13) manufactured before November 1992 have a resistor between the logic ground and chassis ground. This resistor could be damaged if the wiring recommendation described within the attention box on the previous page is not followed. See the figure below for the location of the resistor.
System Installation Recommendations Master Control Relay 3–7 A hard-wired master control relay (supplied by you) provides a convenient means for emergency controller shutdown. Since the master control relay allows the placement of several emergency-stop switches in different locations, its installation is important from a safety standpoint. Overtravel limit switches or mushroom head push buttons are wired in series so that when any of them opens, the master control relay is de-energized.
3–8 System Installation Recommendations Emergency-Stop Switches Adhere to the following points concerning emergency-stop switches: • Do not program emergency-stop switches in the controller program. Any emergency-stop switch should turn off all machine power by turning off the master control relay. • Observe all applicable local codes concerning the placement and labeling of emergency-stop switches. • Install emergency-stop switches and the master control relay in your system.
System Installation Recommendations 3–9 ATTENTION: Your SLC 500 power supply can be damaged by voltage surges when switching inductive loads such as motors, motor starters, solenoids, and relays. To avoid damage to your SLC 500 power supply in these applications, it is strongly recommended that an isolation transformer be used to isolate the power supply from harmful voltage surges. ! Grounded ac Power-Distribution System with Master-Control Relay ➀ Disc.
3–10 System Installation Recommendations Loss of Power Source The chassis power supplies are designed to withstand brief power losses without affecting the operation of the system. The time the system is operational during power loss is called “program scan hold-up time after loss of power.” The duration of the power supply hold-up time depends on the number, type and state of the I/O modules, but is typically between 20 ms and 3 seconds.
System Installation Recommendations Safety Considerations 3–11 Safety considerations are an important element of proper system installation. Actively thinking about the safety of yourself and others, as well as the condition of your equipment, is of primary importance. Several safety areas are discussed below. Disconnecting Main Power The main power disconnect switch should be located where operators and maintenance personnel have quick and easy access to it.
3–12 System Installation Recommendations Periodic Tests of Master Control Relay Circuit Any part can fail, including the switches in a master control relay circuit. The failure of one of these switches would most likely cause an open circuit, which would be a safe power-off failure. However, if one of these switches shorts out, it no longer provides any safety protection. These switches should be tested periodically to assure they will stop machine motion when needed.

Setting Up the DHĆ485 Network The information in this appendix will help you plan, install, and operate the SLC 500 in a DH-485 network. This chapter also contains information that describes the DH-485 network functions, network architecture, and performance characteristics.
A–2 Setting Up the DH-485 Network DH-485 Token Rotation A node holding the token can send any valid packet onto the network. Each node is allowed only one transmission (plus two retries) each time it receives the token. After a node sends one message packet, it attempts to give the token to its successor by sending a “token pass” packet to its successor. If no network activity occurs, the initiator sends the token pass packet again.
Setting Up the DH-485 Network A–3 Other devices that use the DH-485 network include those in the table below. Catalog Number 1746-BAS 1747-KE 1770-KF3 1784-KR 1785-KA5 Description BASIC Module DH-485/DF1 Interface Module DH-485/DF1 Interface Module PC DH-485 Interface Module DH+t/DH485 Gateway Installation Requirement SLC Chassis Function Publication Provides an interface for SLC 500 devices to foreign devices.
A–4 Setting Up the DH-485 Network 1747-AIC Isolated Link Coupler for DH-485 The isolated link coupler (1747-AIC) is used to connect SLC 500 family devices to the DH-485 network (as shown on page A–5). The coupler provides a 6-position removable terminal block for connection to the DH-485 communication cable. Network connections for SLC 500 processors are provided by the Catalog Number 1747-C11, 304.8 mm (12 in.) cable supplied with the link coupler.

A–6 Setting Up the DH-485 Network Configuring the SLC 5/03, SLC 5/04, and SLC 5/05 Channel 0 for DH485 The RS-232 port (channel 0) of the SLC 5/03, SLC 5/04, and SLC 5/05 processor can be configured for DH485 protocol. Refer to your programming software user manual for software configuration information. You can connect channel 0 of the SLC 5/03, SLC 5/04, and SLC 5/05 processors to a DH485 network using the 1747-CP3 cable and a 1761-NET-AIC Advanced Interface Converter (AIC+).
Setting Up the DH-485 Network Important Planning Considerations A–7 Carefully plan your network configuration before installing any hardware.
A–8 Setting Up the DH-485 Network • If you do not run the cable through a contiguous metallic wireway or conduit, keep the communication cable at least 0.15 m (6 in.) from ac power lines of less than 20A, 0.30 m (1 ft) from lines greater than 20A, but only up to 100k VA, and 0.60 m (2 ft) from lines of 100k VA or more. • If you run the cable through a contiguous metallic wireway or conduit, keep the communication cable at least 0.08 m (3 in.) from ac power lines of less than 20A, 0.15 m (6 in.
Setting Up the DH-485 Network A–9 The following sections explain network considerations and describe ways to select parameters for optimum network performance (speed). Number of Nodes The number of nodes on the network directly affects the data transfer time between nodes. Unnecessary nodes (such as a second programming terminal that is not being used) slow the data transfer rate. The maximum number of nodes on the network is 32.
A–10 Setting Up the DH-485 Network Important: The SLC 500 Series A (only) processors set the maximum node address to 31 when power is cycled increasing initialization and response time of the network. Maximum Number of Communicating Devices SLC 500 fixed and SLC 5/01 processors can be selected by two initiators maximum at the same time. Using more than two initiators to select the same SLC 500 fixed and SLC 5/01 processors at the same time can cause communication timeouts.
Setting Up the DH-485 Network A–11 When cutting cable segments, make them long enough to route them from one link coupler to the next with sufficient slack to prevent strain on the connector. Allow enough extra cable to prevent chafing and kinking in the cable.
A–12 Setting Up the DH-485 Network Connecting the Communication Cable to the Isolated Link Coupler Attach the terminal block of the link coupler to the Belden #3106A or #9842 cable as shown below. Additional terminal blocks are available for replacement, see chapter 11.
Setting Up the DH-485 Network A–13 The table below shows wire/terminal connections for DH-485 connectors for Belden #9842.
A–14 Setting Up the DH-485 Network Powering the Link Coupler In normal operation with the programmable controller connected to the link coupler, the processor powers both the link coupler and peripheral device (DTAM, PIC, HHT) — if connected — through the C11 cable. If you do not connect the processor to the link coupler, then use a 24V dc power supply to power the link coupler and peripheral device. The 1747-AIC requires 85 mA at 24V dc.
Setting Up the DH-485 Network A–15 The figure below shows the external wiring connections and specifications of the link coupler. SLC 500 DH–485 LINK COUPLER CAT SER LISTED IND. CONT. EQ. FOR HAZ.

A–16 Setting Up the DH-485 Network You can connect an unpowered link coupler to the DH-485 network without disrupting network activity. In addition, if an SLC 500 controller powers a link coupler that is connected to the DH-485 network, network activity will not be disrupted should the SLC 500 controller be removed from the link coupler.

Appendix B RSĆ232 Communication Interface This appendix provides an overview of the RS-232 communication interface and explains how the SLC 5/03, SLC 5/04, and SLC 5/05 processors support it.
B–2 RS-232 Communication Interface The RS-232 channel on the SLC 5/03, SLC 5/04, and SLC 5/05 processors supports four protocols: • Full-Duplex DF1 (default) • Half-Duplex DF1 (SCADA) • DH-485 • ASCII Communications The SLC and PLC products detailed in this appendix that communicate over the RS-232 communication interface also use the DF1 serial communication protocol. DF1 protocol delimits messages, controls message flow, detects and signals errors, and retries after errors are detected.
RS-232 Communication Interface SLC 500 Devices that Support RS-232 Communication B–3 The SLC 500 product line has three other modules, aside from the SLC 5/03, SLC 5/04, and SLC 5/05 processors, that support the RS-232 communication interface. They are the DH-485 Communication Interface (1770-KF3), the BASIC module (1746-BAS), and the DH-485/RS-232C Interface (1747-KE). All three of these modules can be used with either the SLC 5/01 or SLC 5/02 processor.
B–4 RS-232 Communication Interface DF1 Protocol and the SLC 5/03, SLC 5/04, and SLC 5/05 Processors DF1 protocol combines data transparency (ANSI — American National Standards Institute — specification subcategory D1) and 2-way simultaneous transmission with embedded responses (F1). It is also a peer-to-peer, link-layer protocol. This means that system devices have equal access to messages being sent over the RS-232 communication interface.
RS-232 Communication Interface B–5 Full-Duplex (Point-to-Point) APS Modem Modem APS SLC 5/03 CPU (1747-L532) SLC 5/03 CPU (1747-L532) 1747-CP3 DF1 Half-Duplex Protocol DF1 half-duplex protocol provides a multi-drop single master/multiple slave network. In contrast to the DF1 full-duplex protocol, communication takes place in one direction at a time. You can use channel 0 as a programming port, or as a peer-to-peer port using the MSG instruction.
B–6 RS-232 Communication Interface Either half-duplex or full-duplex modem types can be used for the master, but half-duplex modems must be used for the slaves (assuming there is more than one on a multi-drop network).
RS-232 Communication Interface ASCII Communication B–7 ASCII protocol allows you to connect the SLC 5/03, SLC 5/04, and SLC 5/05 processors to serial printers, PCs, and other third party devices. ASCII protocol allows your ladder program to manage ASCII data. SLC 5/03 Processor Modular Controller 1747-CP3 DF1 Communication Protocol Modems Overview RS-232 Channel 0 You can connect the SLC 5/03, SLC 5/04, and SLC 5/05 processors to several different types of modems.
B–8 RS-232 Communication Interface Wiring Connectors for RS-232 Communication To connect Allen-Bradley devices with other devices over RS-232, you must wire the cable connectors so that communication can occur through the cabling, which provide the interface between devices. Types of RS-232 Connectors The figure below show male connectors, and their pinout locations, for Allen-Bradley devices.

Appendix C Setting Up the DH+ Network This appendix provides an overview of the Data Highway Plus (DH+) communication protocol and explains how the SLC 5/04 processors support it.
C–2 Setting Up the DH+ Network SLC 5/04 Processors and DH+ Communication The SLC 5/04 processors let you operate DH+ communication protocol by means of the DH+ communication channel 1. The SLC 5/04 processors also support DF1 full-duplex protocol, DF1 half-duplex master and slave protocol, ASCII, or DH-485 via its RS-232 port, channel 0. The 3-pin connector, provided with the SLC 5/04 processors, is for actual DH+ communication and the 8-pin connector is for monitoring DH+ communication.
Setting Up the DH+ Network Wiring Connectors for DH+ Communication for SLC 5/04 Processors To connect Allen-Bradley devices with other devices over DH+, you must wire the 3-pin cable connectors so that communication can occur through the cabling. Each device requires its own node address.
C–4 Setting Up the DH+ Network Typical DH+ Network Configuration The following figure illustrates a possible configuration for the SLC 5/04 processor on a DH+ network. You can also use an SLC 500, SLC 5/01, SLC 5/02, SLC 5/03, or SLC 5/05 processor in place of the SLC 5/04 on the DH+ network if the 1785-KA5 card is used with a PLC-5.
Appendix D This appendix provides a brief introduction about control networks. For information on control networks, see the DCM User Manual, Catalog Number 1747-NM007, RIO Scanner User Manual, Publication Number 1747-6.6 and the DeviceNet Scanner Configuration Manual Publication Number 1747-6.5.2.
D–2 Control Networks Each 1747-SN Scanner supports 4 logical racks of 256 I/O each per logical rack. If large amounts of data needs to be transferred to a device such as a PanelView Operator Interface, the 1747-SN Series B Scanner supports block transfer of up to 64 words of data. Up to 16 devices can be connected to a single remote I/O network. The SLC system supports multiple 1747-SN scanners if more devices are required to be controller by a single SLC processor.
Control Networks DeviceNet Network D–3 A device network connects plant floor devices directly to the control system (e.g., SLC 500 controller) reducing the number of I/O interfaces and wiring associated with a typical hard-wired solution. The DeviceNet communication network is a completely open device network and has the support of industry’s leading sensor, actuator, and control manufacturers.

G–2 Communicating with Devices on an Ethernet Network SLC 5/05 Performance Considerations Actual performance of an SLC 5/05 processor varies according to: • size of Ethernet messages • frequency of Ethernet messages • network loading • the implementation of and performance of your processor application program Optimal Performance: PC to SLC 5/05 Processor (2-node Ethernet network) SLC 5/05 and PC Connections to the Ethernet Network Operation Words MSG per second ms per MSG Words per second Single
Communicating with Devices on an Ethernet Network G–3 Ethernet Channel 1 8-Pin 10Base-T Connector The Ethernet connector is an RJ45, 10Base-T connector.
G–4 Communicating with Devices on an Ethernet Network Ethernet Connections TCP/IP is the mechanism used to transport Ethernet messages. On top of TCP, the Client/Server Protocol is required to establish sessions and to send the MSG commands. Connections can be initiated by either a client program (INTERCHANGE or RSLinx application) or a processor.
Communicating with Devices on an Ethernet Network Configuring the Ethernet Channel on the SLC 5/05 Parameter G–5 There are two ways to configure the SLC 5/05 Ethernet channel 1. The configuration can be done via a BOOTP request at processor powerup, or, by manually setting the configuration parameters using RSLogix 500 Programming Software. The configuration parameters are shown below and the configuration procedures follow.
G–6 Communicating with Devices on an Ethernet Network The BOOTP request can be disabled by clearing the BOOTP Enable parameter in the channel Configuration File. When BOOTP Enable is cleared (disabled), the SLC 5/05 uses the existing channel configuration data. Important: If BOOTP is disabled, or no BOOTP server exists on the network, you must use SLC 500 programming software to enter/change the IP address for each processor. See page G–5 for that configuration procedure.
Communicating with Devices on an Ethernet Network G–7 Important: Do not use the BOOTP utility disk if you already have INTERCHANGE software installed. Instead, use the boot-server capabilities that came with your INTERCHANGE software. Install the DOS/Windows BOOTP server To install the DOS BOOTP server: 1. Put the utility disk that came with your processor in your disk drive. 2. Change directory to the disk drive. 3. Type install, and press [Enter]. 4. The software is installed in C:\ABIC\BIN.
G–8 Communicating with Devices on an Ethernet Network 2. Make one copy of the SLC 5/05 processor template for every SLC 5/05 processor in your system. 3. Edit each copy of the template as follows: A. Replace plc5name with the name of the SLC 5/05 processor. Use only letters and numbers; do not use underscores. B. Replace aa.bb.cc.dd with the IP address to be assigned to the processor. C. Replace xxyy with the last four digits of the hardware address.
Communicating with Devices on an Ethernet Network G–9 Based on this configuration, the BOOTPTAB file looks like: # # Legend: gw –– gateways ha –– hardware address ➀ # # # ht –– hardware type ip –– host IP address sm –– subnet mask # # vm –– BOOTP vendor extensions format tc –– template host ➁ #Default string for each type of Ethernet client defaults5E: ht=1:vm=rfc1048 #Entries for SLC 5/05 processors: sigma1: tc=defaults5E:ip=12.34.56.1:ha=0000BC1D1234 sigma2: tc=defaults5E:ip=12.34.56.
G–10 Communicating with Devices on an Ethernet Network Running the DOS-Based Utility To run the boot-server utility, DTLBOOTD.EXE, follow these steps: 1. At the DOS prompt, type: DTLBOOTD [–D] [–T ] [–B ] [–F ] [configfile] [logfile] Parameter Description -D provide additional information for debug purposes. –T exit after seconds of inactivity. –B exit after answering number of boot requests.
Communicating with Devices on an Ethernet Network Using Subnet Masks and Gateways G–11 Configure subnet masks and gateways using the Ethernet channel 1 configuration screen: Important: If BOOTP is enabled, you can’t change any of the advanced Ethernet communications characteristics.
G–12 Communicating with Devices on an Ethernet Network Manually Configuring Channel 1 for Processors on Subnets If you are manually configuring channel 1 for a processor located on a subnet, deselect the “BOOTP Enable” option by clicking on the checked box. See the table below to configure the subnet mask and gateway address fields for each processor via your programming software.
Communicating with Devices on an Ethernet Network G–13 Using BOOTP to Configure Channel 1 for Processors on Subnets Configure the BOOTPTAB file according to the subnet mask and gateway address for each SLC 5/05 processor on the link. See the example below and the corresponding BOOTPTAB file on the next page. Important: Because BOOTP requests are seen only on the local subnet, each subnet needs its own BOOTP server and BOOTPTAB file.
G–14 Communicating with Devices on an Ethernet Network The BOOTPTAB files that correspond to this example looks like: # # # # # # # Legend: gw –– gateways ha –– hardware address ht –– hardware type ip –– host IP address sm –– subnet mask vm –– BOOTP vendor extensions format tc –– template host #Default string for each type of Ethernet client defaults5E: ht=1:vm=rfc1048:sm=255.255.255.0 #Entries for SLC 5/05 processors: iota1:\ tc=defaults5E:\ gw=130.151.194.1:\ ha=0000BC1D1234:/ ip=130.151.194.
