Recorders and Wireless I/O integrated

The following information will provide a method of setting up Modbus Master / Slave communications between a Recorder 6100A/6180A (Master) and the WPR9-2222P (Slave).

Setting up a 6100a/6180a as a Modbus Master

Step 1 Log in as Engineer by pressing the top right hand button and then selecting Engineer:

Step 2 Enter your password (as default 100)

Step 3 Go to connections configuration

Step 4 Set-up the serial connection

• Set desired software protocol (ASCII/MODBUS)

• Set desired hardware protocol (RS232/RS485)

• Set Baud rate/stop bits/ parity

Step 5 Go to Master Comms configuration

Step 6 Check the enable block

Step 7 Set-up and detect the slave device

• Choose the connection type (serial 1/ serial 2/ ethernet)

• Choose the Modbus address

• Select detect this slave

Step 8 Go to the channel configuration

Step 9 Choose Master Comms as your input type

Step 10 Set-up the channel to display the value

• Choose the slave device

• Choose the Modbus function code

• Enter the desired Modbus register

• Select the data type (16 bit integer)

Step 11 The actual reading should appear.

WPM9-1W115KK setup:

• Power up state

  • Power LED – ON steady – red

  • RSSI LED – Off

  • RF Data LED - Off

• Connect PC to wireless modem serial port and open software.

• Check firmware version (2067) and make sure the same firmware version is used on all wireless modem and wireless I/O in the network.

• Change setting to match image below.

  • Channel Number: 00

  • Network Identifier: 0011

  • Destination Address: FFFF

  • Baud Rate: 9600

  • Parity: None

  • Stop Bit: 1 Stop Bit

  • Flow Control: No software flow control

WPR9-2222P setup:

• Power up state

  • Power LED – ON steady – red

  • RSSI LED – Off o RF Data LED – Off

• Connect PC to wireless modem and open software.

• Check firmware Version (2067) and make sure the same firmware version is used on all wireless modems and wireless I/O in the network. (see below)

Change setting to match settings below:

• Region: Other

• Channel Number: 00

• Network Identifier: 11

• Communication Mode: Modbus

• Modbus Address: 2

The image below displays the communication setting relationship between the wireless modem and wireless I/O.

The Channel Number and Network Identifier must be the same for the modules to communicate

Connecting to the Chessell 6100A

• After programming the Chessell 6100A (Modus master) to poll and display the WPR9-2222P connect the WPM9-1W115K RS-232 port to the 6100a.

WPM9-1W115K RS-232 Serial connections:

• Port 1 is a configured as a DTE RS-232 port. This will connect to the WPM9-1W115K, DB9 RS-232 using a standard straight through cable.

• Minimum required connections between the 2 units are TX, RX, and ground.
