We have here on a 10-years old machine a Westinghouse PLC with CPU labeled PC-503.
I believe it's actually a Siemens PLC.
Anybody knows which?
Is it is still on the market ?
I/O cards compatible with newer PLCs ?

Thanks in advance,
eitan

 

It's a S-5 100-U Siemens, 103 processor and is still supported by siemens.

 

Eitan,

You are correct. This was a brand labeled Siemens 100U CPU 103 processor. Westinghouse brand labeled the Siemens 100U (PC-500 series) and 115U (PC-2000 series) processors. These were also brand labeled by Cutler Hammer around the same time.

We continue to support both of these products as well.

Thanks. Joe
