    Here is the wiring diagram I used...

     I'm starting to think my problem is the drivers.  The older Proface does not have a driver for the CJ2 series PLC, only the CJ1.  

    I used the driver for the CJ1 with the hope it would also work with the CJ2.  No luck.  

    There must be a difference between protocols used be the CJ2 versus the CJ1 PLCs.

    Hello All,

    I am trying to get an older GP2401H (Proface HMI) to communicate with a newer CJ2H (Omron PLC).  

    Everything I tried has failed.  I think my problem is on the PLC side.  

    Below are the details...

    ...Proface...

    GP2401H-TC41-24V

    GP-PRO/PB3 for Windows

    ...Omron PLC...

    CJ2H-CPU66-EIP

     

    Need to use the serial port on the CJ2H because the GP is only serial (RS232).

     

    Thanks for checking this out and please let me know what you think.
