I tested a communication between a Magelis HMI (Schneider) and a FCS honeywell in RS422 .
It doesn't communicate.
It works in RS232, so I need your help.

What protocol is the FCS Honeywell using? RS422 only indicates the electrical configuration of the interface. I would also ask that you provide me with the specific Magelis part number and the version number of the configuration software being used.

Since you having it working with the RS232 interface I would assume that you have the proper protocol selected. Can you send me a wiring diagram of how you currently have the system wired with RS422?

The problem is solved now, the customer inverted the communication lines A and B so it was impossible to communicate.

Thanks
