  1. OMRON CJ2M-CPU13 - Serial port communication

    I  am using 2CPUs.  CPU1 is physically connected to ID231 , and CPU2 is connected OD232. I tried to connect them via serial comm ( CPU1 as master and CPU2 as slave) and connect laptop to CPU1 for programming. when I went online, CPU1 detects ID231 ( 0000) which is correct, but CPU2 detect also ID231 (0000) . i tried to  change manually the slot , but shown error while uploading. I connected laptop  to CPU2 and tried to get i/o info online,  then OD232 detected. Any idea why OD232 wasn't detected while  connecting CXONE to CPU1 and two CPUs are serially linked.

  3. OMRON CJ2M-CPU13 - Serial port communication

    Hi all, My serial cable as attached pic. I used this program  as below.  But when i use simulator i can see hexa output in 3100 & 0000. But when i go online, i cant see the output on 3100. My objective of this project is to give some inputs in cpu and get the output from cpu2.?

    Thanks a lot.  
  6. Hi to all, I have two queries about CJ2M-CPU13. 1) Can i use the in built serial port (RS232C) to the GUI or HMI? 2) Can i use the in built serial port (RS232C) to connect two CJ2M-CPU13s? I have only limited experience and knowledge in the PLC. I would like to see a step by step instruction video or tutorial notes.  If any of you any information pls share and help me.   Appreciate all help and thanks.
