Hi DuynvdESTC,

There is no limitation for CN4100 with PCS7 as it shares the data using communication block (S7 Communication PUT/GET).

(Note: To maintain the healthy execution of main program, In the hardware configuration you can specify a communication load value between 5% and 50%. The default value is 20%.)

You can configure more than 1 CN4100 module.

You will get the required and relevant data in below click and the link contains 

Integration of third-party systems, package units, safety integrated systems (SIS) with SIMATIC CN 4100 in SIMATIC PCS 7

Hope it helps you!

 due to the large number of signals (2500), we must place more than one cn4100 per controller (maybe 2 o 3 per AS410). Is it possible ?
