Dear Experts,

Please guide me I have a I/O card installed at my s7200 whose serial no is 6ES7223-1PL22-0XA8 (EM223 CN).

Can I replace this module with serial no: 6ES7223-1PL22-0XA0 (EM 223)?

Will my I/Os work normal after replacement.?

What is the basic difference between EM223 and EM223CN?

Hello Hassan Raza,

Well basically both modules are the same, but CN versions are built for Chinese market only and support Chinese editor.

regards

difference between EM223 and EM223CN;

EM223 can connect with all CPU xxx  and CPU xx CN ( international  and china )

EM223CN only connect with CPU xx CN ( only China)
