Genst,
Could You please advise how can I connect to CJ1M CPU12 - shown in attached picture.
DB9 port is used for communication with remote input/outpus rack.
There is this small portabove DB9, but first I don't know what cable should I use and seconde I don't know if it is possible to usi this port when PLC talks on DB9 with remote input/output rack.
I want to connect to CX-programmer to be able to online troubleshoot PLc program.
thanks in advance.
