Note
Communication via an PNIO interface
If you want to use an PNIO interface of the module for communication in system operation,
you must also network this in Step 7 / HW Config / NetPro.

Free S7 connections can be used for any of the above communication services.
Note
Communication service via the PROFIBUS DP interface
A fixed default timeout of 40 s is specified for communication services using S7 connection
resources. If you operate those communication services via a PROFIBUS DP interface at a
low baud rate, operation in configurations with a Ttr (Target Rotation Time) < 20 s is
ensured.
