Connecting OP27 to OMRON CJ1M

[PassionFingers]

We have a client who wants to connect a Siemens OP27 HMI to his OMRON CJ1M-CPU11 via RS232. Would anyone be able to point me to a cable pinout to achieve this?

I go crazy trying to navigate the Siemens website looking for the pinouts for the OP27.

PassionFingers,

Don't forget that the CJ1M RS232 port is not a "standard" pinout! See below.

Hope this will help.
