CM 1542-1 vs CP 1543-1

Gents,

What is in the simple words difference between communication module CM 1542-1 and  communication processor CP 1543-1.

I need to add my S7-1500 PLC into additional profinet network and I'm not sure which one should I use.

I agree with the prior post.

The CM-1542-1 uses the existing s7-1500 plc's CPU to manage the additional communications load.  The CP-1543-1 is like adding a co-processor to manage the additional communications.  The PLC offloads the work.

The CP will take more time to properly configure.  The CM will be easier to configure and make work for your application.

If you find after adding the CP that the PLC scan time is too slow, you can upgrade to the CP.

Odds this will happen is extremely low - unless you are already close to have too slow of a control system with the existing system.

Hi Gents,

Is the CM 1542-1 manageble?
