hi everyone,
I have a S7 313C Cpu communicating with a pro-face touch screen (AGP 3000 Series), the problem is we found out that the cable communicating between these unit cannot be swap, we accidently swap it & cause the communication port on the PLC burnt & also on the touch screen port. As now we unable to link to both my PLC & my touch screen.
From the circuit of the communication cable, i think we shorted pin 7 & pin 8 inside the S7 communication port. Pin 7 i think got internal DC24V supply. correct me if i am wrong.
i would like to know, if we could repair the the S7 communication port ourself or check if the communication port really faulty.
Thanks!
Regards,
sttchui
