Hello, I am going to be adding plc on press welding machine. the machine has PLC FX3U-16M and attached with 15 16points I/O module. is there any best way to connect 1 HMI with both 2 PLC ?

Which PLC will you be adding another FX3U ? Which GOT/HMI ?

[CangkeMan]

yes Mr @Gambit i am adding fx3u 16mt and gs2107-wtbd

[Gambit]

I would add an FX3U-ENET-ADP and connect it via athernet

[CangkeMan]

I see, is it possible sir to using rs422 same way like ethernet connection

[Gambit]

Probably but I would have to check but for speed and ease i would still use the ADP.
Also the distance would be better between HMI and Controller
