Omron TCP/IP

Kar Hei Lau

Hi All,

Currently I have a ⁠OMRON CJ2M CPU14 with OMRON CJ1W-ETN21. The plc programmer told me that he converted the FINS to Modbus TCP/IP so I tested to use Modicon- MBTCP all of the drivers but not working. Is there any solutions to overcome this issue or what items that I need to look for?

     Hi  ,

    I suggest that you download a copy of Modbus Tester from Schneider Electric website - https://www.se.com/au/en/faqs/FA180037/ (how-to video is also available on this website. the tool is very easy to use), and use this tool to confirm that the configured PLC supports Modbus TCP/IP. If the test result is positive, it could be misconfiguration in your OI server.

    Hope this would help.

    Regards,

    Jacky

    Thanks Jacky for you guide, I manage to solve the problem.
    I found out that the PLC only accepting one connection at a time only. If I running another scanner like modscan and Modbus Tester it will block my connection from SMC that try to connect to which I keep failing to connect. Once I disconnect the scanner connection and let SMC to connect, it works well and need to fine tune some settings inside the driver.
