WI-GTWY-9-xxx Wireless Gateway Chapter 1 User Manual V1.18 INTRODUCTION 1.1 Overview The Wireless Gateway products provide a wireless interface between various fieldbus protocols used in process and automation applications. The WI-GTWY-9-xxx includes an integral 900MHz license-free radio transceiver, and WI-I/O 9 transfers transducer and control signals (I/O) using a highly secure and highly reliable radio protocol.
WI-GTWY-9-xxx Wireless Gateway • Introduction v1.18 Combined networks of the above. The WI-GTWY-9-xxx has eight on-board discrete I/O. Each I/O point can be configured individually as a contact input signal, or a discrete output signal. Input signals can be sent via its fieldbus connection to a host device (PLC, DCS etc) or be transmitted by radio to other WI-I/O 9-x units. The output signals can be driven by a host device, or linked to inputs on remote WII/O 9-x units.
WI-GTWY-9-xxx Wireless Gateway User Manual V1.18 The Modbus/DF1 WI-GTWY-9-MD1 has 4300 general-purpose I/O registers. Each discrete, analog and pulse I/O point takes up one register. 1.1.2 Profibus WI-GTWY-9-PRx The Profibus WI-GTWY-9-PR1 provides Profibus-DP Slave functionality according to EN 50170. Profibus is a popular automation fieldbus that originated in Germany and is used extensively by Siemens and other automation suppliers.
WI-GTWY-9-xxx Wireless Gateway Introduction v1.18 bytes is 2000 (4000/8 + 750*2). The total number of I/O is 3250 which is less than the total limit of 4300. 1.1.3 Ethernet WI-GTWY-9-ET1 The Ethernet WI-GTWY-9-ET1 provides several different types of Ethernet functionality: ♦ Modbus TCP. Modbus TCP uses Modbus as a base protocol within an Ethernet communications structure. The WI-GTWY-9-xxx provides class 0, 1 and partially class 2 slave functionality. ♦ EtherNet IP.
WI-GTWY-9-xxx Wireless Gateway User Manual V1.18 An “output” is a value coming into the WI-GTWY-9-DE1 via the fieldbus (that is, a value written to the WI-GTWY-9-DE1 from the DeviceNet master). An input is a value going out from the WI-GTWY-9-DE1 via the fieldbus (a value read by the DeviceNet master). So a DeviceNet WI-GTWY-9-DE1 can normally handle up to 4096 (512 x 8) discrete inputs or 512 low resolution analog inputs or 256 (512 x ½) high resolution analog inputs, or some combination in between.
WI-GTWY-9-xxx Wireless Gateway Introduction v1.18 9-xxx Radio Interface. The radio port also creates the correct radio message to set outputs on the remote WI-I/O 9-x modules. The WI-I/O 9-x protocol is an extremely efficient protocol for radio communications. Radio messages can be sent using exception reporting - that is, when there is a change of an input signal - or by read/write messages. Each message can comprise a single I/O value, or multiple I/O values (termed a “block” of I/O).
WI-GTWY-9-xxx Wireless Gateway User Manual V1.18 Where additional discrete or analog I/O is required, an external expansion I/O module can be connected to the RS485 port of the WI-GTWY-9 module. See section 4.15 for more details on this. Note: Serial Expansion modules can only be used with the WI-GTWY-9-MD1 unit under certain circumstances. • WI-GTWY-9-MD1 is configured as “Repeater-only” • WI-GTWY-9-MD1 is configured as a Modbus Master and WI-I/O-EX serial expansion modules are used as Modbus Slaves.
WI-GTWY-9-xxx Wireless Gateway Introduction v1.18 WI-I/O 9-x modules can transmit input messages directly to outputs on other WI-I/O 9-x module, as well as the WI-GTWY-9-xxx. The same input can be transmitted to different addresses by entering two "mapping" configurations at the remote module. Normal WI-I/O 9-x Messages I/O registers in a WI-GTWY-9-xxx can be configured (mapped) to outputs at remote WI-I/O 9-x modules, or I/O registers in WI-GTWY-9-xxx modules.
WI-GTWY-9-xxx Wireless Gateway User Manual V1.18 WI-GTWY-9-xxx “sees” a large number of changes in its database at the one time. For example, if a host writes a block of 100 signal values to a WI-GTWY-9-xxx, and 20 of these values have changed since the last write-operation. If the block is mapped to another WIGTWY-9-xxx, then the WI-GTWY-9-xxx can transmit all 20 values in one radio message, instead of 20 messages.
WI-GTWY-9-xxx Wireless Gateway Introduction v1.18 The data concentrator network is different than using the WI-GTWY-9-xxx as a repeater. A repeater re-transmits each message in the same format. A data concentrator collects the I/O values as a block, and transmits the complete block in one transmission. 1.3.4 WI-GTWY-9-xxx Repeaters Any WI-I/O 9-x module can repeat a normal radio message, however only WI-GTWY-9-xxx modules can repeat a block message.
WI-GTWY-9-xxx Wireless Gateway Chapter 2 V1.18 OPERATION 2.1 Start-up The WI-GTWY-9-xxx operating software and the database configuration are stored in nonvolatile memory; however the database I/O register values are lost on power failure (in the same way as a PLC). On start-up, the WI-GTWY-9-xxx sends "start-up poll" messages to remote modules based on the source address of inputs configured in the database (the start-up messages can be disabled by configuration).
WI-GTWY-9-xxx Wireless Gateway V1.18 viewing and modification. For more information, refer to the Configuration section of this document. Each I/O register in the WI-GTWY-9-xxx database has a 16-bit value. It doesn’t matter if the remote I/O is digital (discrete), analog or pulse. The host protocol driver in the WI-GTWY-9xxx will convert the 16 bit value into a value that the host will understand.
WI-GTWY-9-xxx Wireless Gateway V1.18 again when the WI-GTWY-9-xxx receives a message from the remote module. The default configuration is that output updates ARE sent during comms fail conditions.
WI-GTWY-9-xxx Wireless Gateway V1.18 2.3 Database The WI-GTWY-9-xxx database (Radio Interface) has 10 000 registers, each of 16 bit size.
WI-GTWY-9-xxx Wireless Gateway V1.18 The WI-GTWY-9-xxx also monitors its battery voltage and supply voltage. These are stored in registers 4310 and 4311 respectively, as 16 bit values, scaled so that a value of 16384 decimal (hex 4000) corresponds to 8 V, and a value of 49152 (hex C000) corresponds to 40V. A low battery alarm is available at register 4308. This becomes active when the battery voltage falls below 11.3V, and clears when the battery voltage rises above 11.8V.
WI-GTWY-9-xxx Wireless Gateway V1.18 2.4 The Host - WI-GTWY-9-xxx Link For the host device, the WI-GTWY-9-xxx "looks" like a single device (or a "virtual PLC"), containing the I/O for the complete wireless I/O system. 2.4.1 Modbus / DF1 The user selects whether the WIGTWY-9-MD1 should act as a Modbus Master or Modbus Slave or DF1 device. DATA-BUS DATABASE I/O "VIRTUAL PLC" “HOST DEVICE” The data type and baud rate of the serial communications must be configured at the WI-GTWY9-xxx to match the host.
WI-GTWY-9-xxx Wireless Gateway V1.18 to the Ethernet Interface, and handles all radio communications. I/O in the Radio Interface is linked to I/O in the Ethernet Interface in a flexible way via WI Series Configuration Software. The Ethernet Interface provides a total of 2048 input bytes and 2048 output bytes. An Ethernet byte can contain 8 discrete (binary) values, or two bytes can be used for a 16-bit analog or pulse register.
WI-GTWY-9-xxx Wireless Gateway V1.18 The RSSI registers can be read by the host device, or mapped to I/O registers in other WIGTWY-9-xxx modules. The first half of the register (8 most significant bits) will be decimal 0 (hex 00) if the remote module has active communications. If a comms fail status to this address occurs, the most significant bit will be set. For example, if the last message received from #38 is –99dBm, then the 16 bit value of register 4438 will be decimal 99 or hex 0063.
WI-GTWY-9-xxx Wireless Gateway V1.18 address goes into communications failure, then the remote address comms fail status is set ("on" or 1) - every time an input with this remote address receives a radio message, then the remote address comms fail status is reset ("off" or 0). While the remote address comms fail status is set, the WI-GTWY-9-xxx disables any output messages being sent to this remote address.
WI-GTWY-9-xxx Wireless Gateway V1.18 ensure this does not occur. An additional security level using data encryption can also be selected. 3. Malicious operation, or “hacking” This is the problem most associated with security concerns - the ability for someone to access information from a radio system by “listening-in”, or to cause damage by transmitting radio messages to force outputs. A security option can be selected during the module configuration to protect against this.
WI-GTWY-9-xxx Wireless Gateway Chapter 3 V1.18 INSTALLATION 3.1 General The WI-GTWY-9-xxx module is housed in a rugged aluminum case, suitable for DIN-rail mounting. Terminals will accept wires up to 12 gauge (2.5 sqmm) in size. All connections to the module must be low voltage (SELV). Normal 110-240V mains supply should not be connected to any terminal of the WI-GTWY-9-xxx module. Refer to Section 3.3 Power Supply. Before installing a new system, it is preferable to bench test the complete system.
WI-GTWY-9-xxx Wireless Gateway V1.18 Line-of-sight paths are only necessary to obtain the maximum range. Obstructions will reduce the range, however may not prevent a reliable path. A larger amount of obstruction can be tolerated for shorter distances. For very short distances, it is possible to mount the antennas inside buildings. An obstructed path requires testing to determine if the path will be reliable refer the section 6 of this manual.
WI-GTWY-9-xxx Wireless Gateway V1.18 For information on antennas and cables for the WI-GTWY-1 licensed products, please refer to Weidmuller, Inc. or an authorized distributor. Connections between the antenna and coaxial cable should be carefully taped to prevent ingress of moisture. Moisture ingress in the coaxial cable is a common cause for problems with radio systems, as it greatly increases the radio losses.
WI-GTWY-9-xxx Wireless Gateway V1.18 Collinear and dipole antennas should be mounted vertically, preferably no less than 2 ft (0.6 metre) away from a wall or mast to obtain maximum range. The WI-ANT-DPL-0-16 dipole antenna is the preferred antenna for use in industrial plants and factories. 3.2.2 Yagi antennas. A Yagi antenna provides high gain in the forward direction, but lower gain in other directions. This may be used to compensate for coaxial cable loss for installations with marginal radio path.
WI-GTWY-9-xxx Wireless Gateway V1.18 12 – 24 volts AC RMS or 9 – 30 volts DC at the “supply” terminals, or 10.8 –15 volts DC at the “battery” terminals. The power supply should be rated at 1.5 Amps and be CSA Certified Class 2. For use in Class 1 Div 2 explosive areas (USA/Canada), the power supply must be approved for Class 1 Div 2 use. Note: Connect module to the same ground/earth point as the antenna mounting to avoid differences in earth potential during voltage surges.
WI-GTWY-9-xxx Wireless Gateway V1.18 The module may also be powered from an external 11 – 15 VDC battery supply without the need for a “normal” supply connected to “SUP1”. This external battery supply is connected to “BAT+” and “GND” terminals. The positive lead of the external supply should be protected by a 5A fuse SUP1 SUP2 GND BATTERY SUPPLY 11-15 VDC Fuse 5A BAT+ - WI-GTWY + .Upon failure of the normal supply, the module may continue to operate for several hours from a backup battery.
WI-GTWY-9-xxx Wireless Gateway V1.18 3.4 Input / Output The WI-GTWY-9-xxx has eight on-board discrete/digital I/O. These act as both discrete inputs and discrete outputs. 3.4.1 Digital Inputs / Outputs All eight of the WI-GTWY-9-xxx DIO terminals may be used as discrete inputs. These inputs are suitable for voltage free contacts (such as mechanical switches) or NPN transistor devices (such as electronic proximity switches). PNP transistor devices are not suitable.
WI-GTWY-9-xxx Wireless Gateway V1.18 3.5 Serial Port 3.5.1 RS232 Serial Port The serial port is a 9 pin DB9 female and provides for connection to a terminal or to a PC for configuration, field testing and for factory testing. It is also used by the Modbus/DF1 version for fieldbus connection. This port is internally shared with the RS485 - ensure that the RS485 is disconnected before attempting to use the RS232 port. Communication is via standard RS232 signals.
WI-GTWY-9-xxx Wireless Gateway V1.18 RS485 Serial Port RS485 should not be used with the DF1 unit. The RS485 port provides for communication between the WI-GTWY-9-xxx unit and its host device using a multi-drop cable. Up to 32 devices may be connected in each multi-drop network. Note that the RS485 port is shared internally with the RS232 port - make sure that the RS232 port is disconnected before using the RS485 port.
WI-GTWY-9-xxx Wireless Gateway V1.18 3.6 Profibus Port The Profibus RS485 connector is a D9 connector in the top end-plate of the module (see below).

WI-GTWY-9-xxx Wireless Gateway Chapter 4 V1.18 CONFIGURATION 4.1 Introduction A Windows program is provided to configure the WI-I/O 9-x system. The configuration is done on a system basis - referred to as a “project” in the program. After the system configuration is entered, the configuration file can be loaded into each module via the RS232 port.
WI-GTWY-9-xxx Wireless Gateway V1.18 All of these steps must be performed to configure the WI-GTWY-9-xxx module. 4.2 Configuration Program The configuration software is available on a CD, and needs to be installed on your PC before you can use it. The CD contains a setup file called setup.exe. Select the configuration software window on the Product CD and an installation Wizard will guide you through the installation procedure.
WI-GTWY-9-xxx Wireless Gateway V1.18 4.2.1 Program Operation Start the software by either clicking on the start bar and navigating to the Configuration menu or by running WI SERIES.EXE in the directory selected in the setup stage. The Initial screen will appear. From the initial screen, , you can select an existing project, or start a new project. The name of the project will create a new folder which will eventually contain the configuration files for the modules in this system.
WI-GTWY-9-xxx Wireless Gateway V1.18 can also change password at any time by over-typing the passowrd. If you are starting a new project, you have the option of “Enabling Security”. This option enables encryption of the data sent over the radio. please read Section 4.2.2 and the associated warnings before using this option. To proceed with the configuration, doubleclick on the project name on the menu on the left side of the screen. “Units” will appear.
WI-GTWY-9-xxx Wireless Gateway V1.18 The default name for a unit will include the unit address. For example, “WI-GTWY#10” is a WI-GTWY-9-xxx module with unit address 10. You can change the name of a unit - for example, you could replace the default name with “Pump Station 14”.
WI-GTWY-9-xxx Wireless Gateway V1.18 Deleting a Unit A module can be deleted from the configuration by highlighting the unit and selecting “Delete Unit”. 4.2.2 Security There are two security features available. You can enter a password to protect the configuration files, and you can enable security encryption of the radio transmissions. The password can be between 6 and 256 characters. The password is case sensitive and any ASCII characters can be used.
WI-GTWY-9-xxx Wireless Gateway V1.18 • If you do not enable security, there will be no data encryption of the radio messages. This is the default setting. • If a security key has been entered, this key is downloaded into each module as part of the configuration download process. You can download another configuration at any time - if the security key is different, or if there is no security key in the new configuration, the old key will be over-written.
WI-GTWY-9-xxx Wireless Gateway V1.18 The archived configuration files cannot be changed, downloaded or uploaded without the password. If you lose the configuration files, you can regenerate these by uploading the configuration from every module in the system into a new project with a new security key. After uploading each module, download the configuration with the new security key.
WI-GTWY-9-xxx Wireless Gateway 4.3.1 V1.18 Loading from a WI-GTWY-9-xxx If you load a configuration from a WI-GTWY-9-xxx into a “blank” or new project, then the program will not be able to display the mappings from remote modules (as the program does not know what the remote modules are).
WI-GTWY-9-xxx Wireless Gateway V1.18 4.4 Mappings WI-GTWY-9-xxx to WI-I/O 9-x I/O Modules To transfer remote input signals to a WI-GTWY-9-xxx, or transfer a value to a remote output from a WI-GTWY-9xxx, you set up “I/O mappings”. You enter mappings into the source unit, not the destination unit. That is, you configure a mapping at the “input” module. If you want to transfer an input signal at a WI-I/O 9-x module to a WIGTWY-9-xxx register, you enter a mapping at the WI-I/O 9x I/O module.
WI-GTWY-9-xxx Wireless Gateway V1.18 For each “remote input” configured to a WI-GTWY-9-xxx, there is a comms-fail time parameter in the WI-GTWY-9-xxx. If the WI-GTWY-9-xxx does not receive a message destined to that I/O register within the “comms fail” time, then the “comms fail” status for that I/O register will be set - the most significant bit of the status register will be set to 1. The comms fail time should be more than the corresponding update time at the remote input.
WI-GTWY-9-xxx Wireless Gateway V1.18 Change Sensitivities Radio messages to remote modules can be change messages (when the value of the I/O register changes) or update messages (when the update time has elapsed). If a change message is sent, the update period restarts. You can configure the amount of change required to trigger a change message - this is called the change sensitivity. Sensitivities are configured for blocks of I/O registers - that is, each I/O register does not have a unique sensitivity.
WI-GTWY-9-xxx Wireless Gateway V1.18 Update Times To change the update times of output mappings, select the Update Times option. Any I/O registers that have already been mapped to remote outputs will automatically be listed. The default update time is 10 minutes. Changing Multiple Settings You can change the Comms Fail Times or Update Times of several I/O points simultaneously by using the Select feature.
WI-GTWY-9-xxx Wireless Gateway V1.18 4.4.4 Startup Polls You can enter start up polls for remote modules by using the “New Poll Mapping” box. This function is the same as for the WI-I/O 9-x I/O modules. A start-up poll is a special message sent when the WI-GTWY-9-xxx starts up. When the remote module receives a start-up poll, it will immediately respond with update messages for all its inputs that are mapped to the WI-GTWY-9xxx. This allows the WI-GTWY-9-xxx to have correct values on start-up. 4.4.
WI-GTWY-9-xxx Wireless Gateway V1.18 To get around this problem, it is possible to configure “block mappings”. With a block mapping, multiple registers (a “block of registers”) can be transferred together in the one radio message. This improves the efficiency of the radio communications. Read/Write Mappings The mappings can be “read” or “write” mappings. A Read mapping is a request sent to another WI-GTWY-9-xxx to return a block of values.
WI-GTWY-9-xxx Wireless Gateway 4.5.1 V1.18 Entering a Block Mapping Select the “source” WI-GTWY-9-xxx on the left hand menu - select “Block Mappings” and then “New Block Mapping” from the right-hand display. The Block Mapping Configuration display will appear. Select the “Command Type” from the pop-down window in the centre of the display. The red arrow will confirm the direction of the block transfer. Now select the destination module - only the WI-GTWY-9-xxx modules already configured will be shown.
WI-GTWY-9-xxx Wireless Gateway V1.18 Each mapping entered is allocated a status register - the register number appears on the right hand of the Block Mapping display. These registers store relevant status information about the block mapping - the structure of the Block Mapping status registers is shown in Appendix 1. In the above example, the status register for the block mapping has been automatically assigned to register 9500.
WI-GTWY-9-xxx Wireless Gateway V1.18 Each block mapping that is configured is allocated a status register in the range 9500 – 9999 (i.e. one status register for a maximum of 500 possible block mappings). The status register for a given block mapping is shown on the right hand side of the Block Mapping display (under the heading “Status Lcn”). Bit 13 of the associated status register is the “Force bit” - if Bit 13 is turned “on”, then the associated mapping is forced, or triggered.
WI-GTWY-9-xxx Wireless Gateway V1.18 4.5.4 Real-Time The block mapping message can be sent at a real-time by setting the “Period” value. In this example, “period” is set to 6 minutes - the message will be sent every 6 minutes starting at the beginning of each hour. That is, the message will be sent at XX:00, XX:06, XX:12, XX:18, XX:24 …. XX:54 - where XX represents any hour of the day. If “Period” was set to 1 minute, then the message would be sent every minute, on the minute.
WI-GTWY-9-xxx Wireless Gateway V1.18 Setting the Clock The clock within the WI-GTWY-9-xxx can be set by the host device, and read by the host device. The WI-GTWY-9-xxx provides four clock registers for days/hours/minutes/seconds - the registers are 4330 – 4333. On power-up, these registers are set to zero. Reg 4333 increments each second, Reg 4332 increments each minute, Reg 4331 each hour and Reg 4330 each day. The clock registers are used by the WI-GTWY-9-xxx for the real-time-clock trigger.
WI-GTWY-9-xxx Wireless Gateway 4.5.5 V1.18 Change-of-State If a value in the block changes by more than the sensitivity amount, then the block message will be sent (this can only occur for Write mappings). The sensitivity values are set under the “Sensitivity” option as per section 4.6. A delay time can be entered to reduce the number of change triggers in active systems.
WI-GTWY-9-xxx Wireless Gateway V1.18 In the above example WI-GTWY-9#1 is performing a Block Read Request to WI-GTWY-9#2. WI-GTWY-9#1 will send a block mapping request to WI-GTWY-9#2 who will then send a block mapping from its I/O registers 52 for a count of 10 to WI-GTWY-9#2 I/O registers 52 – 61. This Block read will be performed using the real time clock at 10-minute intervals.
WI-GTWY-9-xxx Wireless Gateway V1.18 The Block mapping feature will allow a Write Block Mapping to itself. This could be useful if you have a global output to indicate a comms problem from any remote module by block mapping the internal status registers to a local DIO output. 4.5.9 Comms Fail for Block Mappings Each block mapping has an associated mapping number. Up to 500 block mappings may be entered. A status register is maintained for each block mapping.
WI-GTWY-9-xxx Wireless Gateway V1.18 4.6 Change Sensitivity & I/O Value Scaling 4.6.1 Change Sensitivity “Change” messages for both individual I/O mappings and block mappings use a sensitivity value to trigger the message. Sensitivities are configured for blocks of I/O registers - that is, each I/O register does not have a unique sensitivity. You can configure up to 50 sensitivity values - that is, there can be 50 blocks of registers with different sensitivities.
WI-GTWY-9-xxx Wireless Gateway V1.18 radio channel. A sensitivity value of 1 in 65535 is a change of 0.0015%. If the host device writes an analogue value to a WI-GTWY-9-xxx every 100msec, it will change by at least 1 bit each time. A small sensitivity value will cause a change message to be sent every 100msec. If there are many analogue values in the same situation, then there would be many change messages every 100msec.
WI-GTWY-9-xxx Wireless Gateway V1.18 Scaling is configured in the “Sensitivities” section of the configuration software. If you select a new sensitivity/scaling block, you can select/deselect sensitivity or scaling or both. There is no relationship between sensitivity and scaling we use the same configuration area as it is convenient because both features use blocks of I/O registers. In the first example, a block of I/O registers is configured for both sensitivity and scaling.
WI-GTWY-9-xxx Wireless Gateway The second example shows another I/O block (registers 81 to 1080) that has been selected for scaling only - the sensitivity function has been disabled (these registers will use the default sensitivity of 2000 configured on the main Sensitivity configuration screen). In this example, the full 16-bit range (065535) is scaled to “signed 16-bit values”. A value greater than 32767 (which will be seen as a negative value) can’t be written to the data bus.
WI-GTWY-9-xxx Wireless Gateway 4.6.3 V1.18 Unit Details Number of Transmission Retries. - Configurable value between 0 – 4, If the WI-GTWY-9 does not receive an Acknowledgment from a message it will retry up to this configured amount. Note: Setting to 0 will not allow for any retries. Not recommended for poor radio paths. 4.6.4 Number of TX only transmissions Under I/O mappings and Block mapping’s is an option for the WI-GTWY-9 to send messages as a Transmit only.
WI-GTWY-9-xxx Wireless Gateway V1.18 passed via a repeater it will buffer this message in a queue and then forward on and wait for ACK before it clears the buffer. If system is experiencing high radio message count and poor radio path creating number of retries, cases could exist that the buffers will empty. Enabling the Reset on Buffer Empty feature will reset the module and then continue to operate. 4.
WI-GTWY-9-xxx Wireless Gateway V1.18 The value of a discrete (digital) I/O point is stored in the WI-GTWY-9-xxx database as a hexadecimal ' 0000'(“off”) or hex ' FFFF'(“on”). However the WI-GTWY-9-xxx will respond with either a ‘0’ (“off”) or ‘1’ (“on”) to a digital read command from the Modbus master - these are commands 01 and 02.
WI-GTWY-9-xxx Wireless Gateway V1.18 Supported Exception Codes: Exception Name Code Description 01 Illegal function The module does not support the function code in the query 02 Illegal data address The data address received in the query is outside the initialized memory area 03 Illegal data value The data in the request is illegal 06 Busy Unable to process message 4.7.2 MODBUS Master If you use the WI-GTWY-9-xxx as a Modbus Master, then the host device/s will be Modbus Slave device/s.
WI-GTWY-9-xxx Wireless Gateway V1.18 not respond to the command, then the WI-GTWY-9-xxx will write a ‘FFFF’ value to one of its own registers, configured under “CF Register” - in this case it is register 4800. The “Command Type” selected is a write command (you can select read or write) - which means that the values are sent from the WI-GTWY-9-xxx to the Modbus Slave. The type of write command is a “Digital” write, meaning that the register values will be written as digital/binary values”.
WI-GTWY-9-xxx Wireless Gateway V1.18 The CF Register (“comms fail” register) acts as a digital alarm – the value of the register will normally be 0, and will be set to FFFF (hex) if the slave device does not positively respond to the serial command within Max Retries attempts. In the examples, the same CF Register (4327 – i.e. DOT8) has been used for both serial mappings, such that the local digital output will be activated if the slave fails to respond to either serial command.
WI-GTWY-9-xxx Wireless Gateway V1.18 signal will vary between 16384 (hex 4000) and 49152 (hex C000). A 0-20mA signal will vary between 8192 (hex 2000) and 49152 (hex C000). Pulse I/O Pulse counts from the remote WI-I/O 9-x modules are shown as a 16-bit register. When the register rolls over, from ‘FFFF’ (hex), the next value will be ‘0001’. The register will only have a value of ‘0000’ when the remote module starts up, and the previous count is lost. This value will indicate that the counter has reset.
WI-GTWY-9-xxx Wireless Gateway V1.18 device, and both devices will respond to commands from the other device. The WI-GTWY-9xxx can act as both a command initiator and a command responder. An Application Note and configuration files are available describing how to configure an AllenBradley PLC to communicate with a DF1 WI-GTWY-9-xxx. This is available from the Weidmuller, Inc. website www.weidmuller.
WI-GTWY-9-xxx Wireless Gateway V1.18 value, the new value will be transmitted to the remote WI-I/O 9-x on the radio network. Similarly, if the WI-GTWY-9-xxx receives a command to change a data value, the new value will be transmitted to the remote WI-I/O 9-x module. The DF1 commands are configured in the “Serial Mapping” screen. The serial port should be configured in the same way as the host device. If the WI-GTWY-9-xxx acts only as a command responder, no further configuration is required.
WI-GTWY-9-xxx Wireless Gateway V1.18 Discrete I/O The value of a digital I/O point is stored in the WI-GTWY-9-xxx database as a hexadecimal ' 0000' (“off”) or hex ' FFFF'(“on”). However the WI-GTWY-9-xxx will generate either a ‘0’ (“off”) or ‘1’ (“on”) to a binary file when initiating a “Typed Logical Write” command or responding to a “Typed Logical Read” command.
WI-GTWY-9-xxx Wireless Gateway V1.18 Note: If analog values are read to and written from an integer file in an SLC or Micrologix CPU, integer files contain 16 bit signed values. These represent values in the range -32768 to 32767. The data values from the WI-I/O 9-x modules are treated as 16 bit unsigned values. To convert the data from an analog input, move the data from the integer file to a long file (MOV command) then mask out the high 16 bits (MVM with mask value FFFF).
WI-GTWY-9-xxx Wireless Gateway V1.18 4.9 Fieldbus Configuration All WI-GTWY-9-xxx modules (except MD1) have separate internal hardware comprising the Fieldbus Interface, consisting of a separate microprocessor and appropriate hardware for the network connection. This Fieldbus Interface handles all fieldbus communications, and transfers I/O in the Fieldbus Interface Registers to/from the fieldbus.
WI-GTWY-9-xxx Wireless Gateway Radio Interface V1.18 Fieldbus Interface IN Area Profibus 244 Bytes Modbus/TCP 2048 Bytes Write from I/O Reg Ethernet/IP allows 6 input connections; each connection Max 512 bytes Read from Host Modbus Plus 2048 bytes DeviceNet 512 bytes 10,000 x 16-bit I/O Registers OUT Area Profibus 244 Bytes Modbus/TCP 2048 Bytes Read to I/O Reg Ethernet/IP allows 6 output connections; each connection Max 512 bytes Write from Host Modbus Plus 2048 bytes DeviceNet 512 bytes 4.9.
WI-GTWY-9-xxx Wireless Gateway V1.18 Several different configurable transfer modes are also available for fieldbus mappings to ensure the I/O is formatted according to the requirements of the particular fieldbus protocol or host device. The six possible types of Fieldbus Mapping are outlined in the table below.
WI-GTWY-9-xxx Wireless Gateway V1.18 transfer of digital I/O in cases where it is not desirable (or possible) to use a whole 16-bit register just to store a 0 or 1 value. 4.9.3 Endianess Endianness is the convention that two parties that wish to exchange information will use to send and receive this information if the information needs to be broken into smaller packets, i.e. data transmission, radio, etc.
WI-GTWY-9-xxx Wireless Gateway V1.18 For example Modbus/TCP areas start from location 1, but other fieldbuses may start at location 0. Note: • The Fieldbus Interface IN and OUT Area both number from 0 - that is, there is an input 0 as well as an output 0 (an offset may apply for some protocols).
WI-GTWY-9-xxx Wireless Gateway V1.18 Three Fieldbus Mappings are illustrated in the example above. Note that “Word Address Mode” is selected, meaning that the Fieldbus Interface IN and OUT Areas will be treated as wordaddressed arrays by configuration software. The parameters for each fieldbus mapping were setup using the mapping configuration screen as described above.
WI-GTWY-9-xxx Wireless Gateway V1.18 BIT transfer, that each individual bit in the Fieldbus Interface is transferred to an entire 16-bit I/O Register. Note also that there is a word-location 1 for both the Fieldbus OUT and IN areas. The third mapping is another “Read BIT” mapping, reading 8 bits from Fieldbus OUT Area word-location 1 to I/O Registers 4320 – 4327 (i.e. local DOT 1 – 8). Note here that we are again reading from Fieldbus OUT Area word-location 1 (as with the previous mapping).
WI-GTWY-9-xxx Wireless Gateway V1.18 A status location (4500) may be used to give the host device status information about the Fieldbus Interface. This register will be value 0x0000 if the Fieldbus Interface is “on-line” and communicating with the fieldbus, or value 0xFFFF if it is “off-line”. If you wish to use a status register, select the “Enable Status Location” box. This register could be mapped to a remote module or local output as an alarm. 4.
WI-GTWY-9-xxx Wireless Gateway V1.18 4.11 Fieldbus Configuration - Profibus Master The WI-GTWY-9-xxx-PR2 implements a complete Profibus-DPV0/DPV1 master. The hardware is optimized for high throughput and can be used in mono or multi master networks up to 12 Mbit/s. Up to 125 slaves with a total max of 2048 byte input and 2048 byte output data can be connected. 4.11.1 GSD File Each device in a Profibus network is associated with a GSD file, containing all necessary information about the device.
WI-GTWY-9-xxx Wireless Gateway V1.18 the fieldbus interface for I/O on the Profibus network. I/O in the fieldbus interface must be linked with I/O in the radio interface via appropriate fieldbus mappings (see 4.8 Fieldbus Configuration above) for I/O transfer with the radio network. Configuration of the Profibus network is through the Profibus Network Config tab in WI Series Configuration Software.
WI-GTWY-9-xxx Wireless Gateway V1.18 configuration list). The above example shows a slave device being added to the network at node address 7. Slave Address To change the node address of a slave already configured on the network, locate the slave in the network listview and drag it to the position in the list corresponding to the desired address. Alternately, the slave address can be modified from the module properties page (see below).
WI-GTWY-9-xxx Wireless Gateway V1.18 Group Assignment If the slave supports sync/freeze functionality, it can be assigned to the masters sync/freeze groups by clicking on the checkboxes. The sync/freeze assignment of the groups is also displayed (these can be changed via the master properties dialog). Parameter Assignment A slaves user-specific parameters can be changed via the parameter assignment page.
WI-GTWY-9-xxx Wireless Gateway V1.18 Adding I/O to a Slave The possible I/O combinations for a given slave may be fixed or configurable (i.e. modular) depending on the GSD file for the device. When the I/O configuration is fixed, the fixed I/O are always defined whenever the device is added to the network. However, for modular devices, the I/O configuration must be assigned manually.
WI-GTWY-9-xxx Wireless Gateway V1.18 I/O modules may also have associated user parameter data defined by the corresponding GSD file. The meaning of these parameters (if applicable) is specific to the slave implementation, and may be altered via the Parameter Assignment tab of the Module Properties form. Configuration software also provides an additional I/O module to all slaves that is not defined in the GSD files, which is the Universal Module.
WI-GTWY-9-xxx Wireless Gateway V1.18 network. The User Defined profile allows the bus parameters to be manually configured for special network configurations and should only be used if the user is familiar with the individual Profibus parameters (see Bus Parameters Tab below). The storage format determines if word values are stored in big endian (Motorola – most significant byte has lowest address) or little endian (Intel – Least significant byte has lowest address) format.
WI-GTWY-9-xxx Wireless Gateway V1.18 Tqui The quiet time is the time a modulator needs after recognizing a send frame to switch from send to receive. 0 t_bit <= Tqui <= MIN(31 t_bit, Min. Tsdr - 1) Gap Factor The Gap Factor determines how many token rounds occur before a new active node (master) can be added to the token ring. 1 <= Gap Factor <= 100 Retry Limit The Retry Limits determines the number of attempts (repeated message frames) allowed to access a node.
WI-GTWY-9-xxx Wireless Gateway V1.18 This value can be set for multi master networks with the selected profile Multi Master. Delta Ttr is added to the calculated Ttr to increase the Ttr for using multiple masters in a network. 256 t_bit <= Ttr <= 16.776.960 t_bit Non-adjustable bus parameters Ttr The target rotation time determines the maximum available time for a token pass. During this time all active nodes (masters) obtain the token one time to send data.
WI-GTWY-9-xxx Wireless Gateway V1.18 Profibus Network Configuration Once the GSD file for the Profibus slave has been installed, the slave device can be added to the Profibus network (see Configuration section above). For this example, the slave is a modular device, therefore we add the necessary I/O modules to the slave.
WI-GTWY-9-xxx Wireless Gateway V1.
WI-GTWY-9-xxx Wireless Gateway V1.18 1) Radio Configuration To complete the configuration, the I/O that has now been transferred to the radio interface must be mapped over the radio network. The analog input from the slave is mapped to an analog output at a remote WI-I/O 9-x-1, the 8 x digital output at the Profibus slave will be activated in this example via appropriate mapping from 8 x digital input at a remote WI-I/O 9-x-4 (see below). 4.11.
WI-GTWY-9-xxx Wireless Gateway V1.18 In addition to cyclic data exchange with slave devices, the WI-GTWY-9-xxx Profibus Master also supports a number of acyclic services that may be triggered via a special Message Interface. The message interface is by default disabled, but will become enabled by also enabling a “Status Location” via the fieldbus configuration tab in configuration software.

WI-GTWY-9-xxx Wireless Gateway 4.12 V1.18 Fieldbus Configuration - Ethernet The WI-GTWY-9-xxx provides the following Ethernet functionality: 1. Modbus/TCP. The module supports the Modbus/TCP protocol and conforms to the Modbus/TCP specification 1.0 (full information on this protocol can be obtained from http://www.modicon.com/openmbus/index.html). Refer to section 4.12.2 below for configuration details. 2. EtherNet/IP.
WI-GTWY-9-xxx Wireless Gateway V1.18 255) separated by periods, where each integer represents the binary value of one byte in the IP address. This is called dotted-decimal notation. Example: 169.254.100.175 Subnet Mask An IP Address is divided into two main parts subnet ID and host ID. All devices on the same local network must have the same subnet ID, but a unique host ID. To separate these two parts a subnet mask is used.
WI-GTWY-9-xxx Wireless Gateway V1.18 amount of time, the WI-GTWY-9-xxx will timeout and disconnect that connection. Note that there can be several active connections at the same time - only the inactive connection will be disconnected. Enable Ethernet Debug Select this box if you wish to enable Ethernet Diagnostics on the WI-GTWY-9-xxx via configuration software (see section 6.3 for details).
WI-GTWY-9-xxx Wireless Gateway V1.18 Modbus/TCP Addressing The IN and OUT areas of the Ethernet interface are addressed under Modbus/TCP according to the tables below. Since Modbus uses a 16-bit format, “Word (16-bit) Address Mode” will be automatically applied whenever the “Modbus/TCP” checkbox is checked. If Ethernet/IP is also enabled, the “Disable I/O Instance” option must be selected for each fieldbus mapping to which Modbus/TCP Addressing is to apply.
WI-GTWY-9-xxx Wireless Gateway V1.18 WI-GTWY-9-ETH1 #1 Appropriate Modbus prefixes may need to be added to the Modbus Address depending on the host device. For example, a “word write” fieldbus mapping in the WI-GTWY-9-xxx to Modbus location 10, can be read by a host device as 30010 (30000 for an input register + 10 as the address).
WI-GTWY-9-xxx Wireless Gateway V1.18 locations 16385 – 16392 into I/O registers 4300 – 4307 (DOT 1-8). The Modbus/TCP host device would write to these as Modbus addresses 016385 – 016392 (using the 0x prefix to denote output coils). Connect Timeout The Connect Timeout parameter in the Modbus TCP section of the display refers to the Modbus TCP functionality of the module.
WI-GTWY-9-xxx Wireless Gateway V1.18 WI-GTWY-9-ETH1 #5 the required I/O registers to the Fieldbus Interface, as described above in the Profibus and Modbus/TCP sections. An “I/O Instance” for each fieldbus link must also be specified so that the configured I/O data is made available to one of the six possible Ethernet connections. In this example, 40 I/O Registers (80 bytes) are transferred to I/O Input Instance 1 (i.e. Ethernet connection 1).

WI-GTWY-9-xxx Wireless Gateway V1.18 4.13 Fieldbus Configuration – DeviceNet 4.13.1 DeviceNet Introduction DeviceNet is a broadcast-oriented communications protocol based on the Controller Area Network (CAN). The physical fieldbus is a shielded copper cable composed of one twisted pair and two cables for the external power supply. The baud rate can be changed between 125k, 250k, and 500kbit/s via Configuration Software or DIP-switch.
WI-GTWY-9-xxx Wireless Gateway V1.18 Each device in a DeviceNet network is associated with an EDS file, containing all necessary information about the device. This file is used by the network configuration tool during network configuration. The EDS file can either be downloaded from the Weidmuller, Inc. website, or found on the Product CD supplied with the module. 4.13.
WI-GTWY-9-xxx Wireless Gateway V1.18 4.14.2 Modbus Plus Addressing Modbus Plus node addressing can be set using switches or via configuration software. To use the switch address settings, the “Enable Switch Address” option in configuration software must be selected, otherwise switch settings are ignored. NOTE – software address configuration is the recommended option if use of the GDB Offset and Count parameters is required (see section 4.11.4).
WI-GTWY-9-xxx Wireless Gateway V1.18 The WI-GTWY-9-xxx Modbus Plus supports the following exception responses: - (0x01) Illegal function for the addressed slave - (0x02) Illegal data address within the information field for the addressed slave - (0x03) Illegal data value in the information field for the addressed slave The WI-GTWY-9-xxx Modbus Plus supports up to 1024 words of output data and 1024 words of input data.

WI-GTWY-9-xxx Wireless Gateway Chapter 6 V1.18 DIAGNOSTICS Bfore installing a new system, it is always best to set up the system on a bench to test the system configuration. It is always easier to detect problems when the modules are together. After installation, test the radio paths, using the radio strength testing function described later in this section. Record the radio strength and background noise measurements for later reference (refer section 6.2.2 for this feature).
WI-GTWY-9-xxx Wireless Gateway V1.18 are only used for simple radio tests such as “RSSI Measurement” or “Tone Reversals”.

WI-GTWY-9-xxx Wireless Gateway Appendix 2 User Manual IT Functionality WI-GTWY-9-xxx-ET1 Ethernet module only Filesystem The filesystem is a fixed-size storage area with a hierarchical directory structure. Any user- or application data can be stored in files within the filesystem. Files can be grouped in directories for increased readability. The filesystem features two security levels. Depending on security level, different users can have access to different files and directories.
Appendix 2 • IT Functionlity Admin Mode Admin users have full access to the filesystem through FTP and Telnet. This enables the user to access areas of the filesystem that are restricted or inaccessible in Normal mode. The Admin user accounts are defined in the file ‘ad_pswd.cfg’. If no admin password file (See “System Files”) is found or Admin Mode is set by configuration software, the module will run in Admin Mode; i.e. all users will have Admin access rights.
WI-GTWY-9-xxx Wireless Gateway User Manual web_accs.cfg To protect a directory from web access, a file called ‘web_accs.cfg’ must be placed in the directory to protect. This file shall contain a list of users that are allowed to browse the protected directory and its subdirectories. Multiple of these password files may be present in the system, allowing different users to access different files and directories. The file format is the same as for the ‘ad_pswd.cfg’ and ‘sys_pswd.
Appendix 2 IT Functionlity 10.10.12.* [All] *.*.*.* The above example will allow all IP addresses beginning with 10.10.12 to access all protocols in the module. Addresses beginning with 10.10.13 will be able to access the web server, but not the FTP and Telnet servers. The Modbus/TCP and Ethernet/IP servers will accept connections from any IP address. The contents of this file can be redirected by placing the line ‘[File path]’ on the first row, and a file path on the second.
WI-GTWY-9-xxx Wireless Gateway User Manual NOTE: In the current firmware implementation “IP Address”, “Subnet Mask”, “Gateway Address”, and “SMTP Address” will always be overridden by the values used in configuration software (i.e. those values cannot be set by writing to this file). The contents of this file can be redirected by placing the line ‘[File path]’ on the first row, and a file path on the second. This procedure is exactly the same as with the system file “ip_accs.cfg” (see above).
Appendix 2 IT Functionlity Virtual File System The module also contains a virtual file system containing a set of files used to build the default configuration webpage. The virtual file system can be overwritten or disabled, but not erased; A file with the same name in the file system replaces the file in the virtual file system until it is removed. The entire virtual file system can be disabled using configuration software on the Ethernet Settings page.
