Connect PLC to modules via cable?

I have successfully used the extension cable to separate digital and analog I/O on separate DIN rail a few times.  Only one length was available at that time -- and that was quite long.

Hllo Jambo;

Have a look at the following discussion:

Extension rack in S7-1200 

 

You will have to think in terms of Profinet or Profibus-DP or Profinet remote racks to extend the IO modules.

Hope this helps,
