  1. GP2401H to Omron CJ2H

    amccaffe posted a topic in Other Omron Software

    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.

    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.
