  1. GP2401H to Omron CJ2H

    amccaffe replied to amccaffe's topic in Other Omron Software

    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.    

  2. GP2401H to Omron CJ2H

    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.
