[?]: S7-1200 <-> S7-1200 Modbus via RS232

Post by Homeroid_BL » Wed Mar 16, 2011 1:34 pm

Hi all!

If I want to connect two S7-1200 CPUs with RS232 ports on both CPUs, and implement a Modbus RTU communication,
what is the cable pinout of a connecting cable?

Thanks.

Hi!
I am looking for CABLE pinout, not PORT pinout.
