Does anyone have experience setting up a Unigate CL Ethernet IP gateway?
Basically I have a small Modbus RTU RS485 network on the serial side, which consists of three Modbus slaves. The communication settings are 9600, 8N1 and the Modbus slave addresses are 01,02 & 101 (dec). The Ethernet side links to my SCADA running Kepserver OPC server.
Taking Ethernet out of the equation and using Kepserver’s Modbus serial driver, I can successfully poll the Modbus serial data via my RS232/485 serial converter. This proves the Serial side of the gateway is ok.
However, when I connect the CL Ethernet IP gateway (set to transparent mode) and try to poll the data from the Ethernet side (SCADA), I can’t read anything!
My Unigate CL settings are as follows:
Ethernet side
IP: 192.168.1.150
SN: 255.255.255.0
Serial Side
Protocol Type : Transparent (options here to change the protocol type to Modbus Master, Modbus slave, Universal, RK3964)
Baud: 9600
Start: 1
Stop: 1
Parity: none
Fieldbus
Data Mode: Cyclic (options here to change to on-change or trigger)
Fieldbus block size input: 32
Fieldbus block size output: 32
I’ve tried all the combinations I can think of, i.e. ;
The Unigate CL Ethernet IP also has "scripting" capabilities, however the supplier thinks I don’t need to add any additional scripts because my application is very simple.
I have tried to contact the supplier with regard to this issue, but have had no response as yet (they may contact me on Monday).
Any help would be greatly appreciated.

- Changed Protocol type
- Changed Data mode
- Swapped my Tx, Rx (and for each combination change)
- Increased / decreased the Block sizes
