PROFINET with 2 controllers

Operation with two controllers is only possible in conjunction with an F-CPU.

SINAMICS S120 allows two control systems to be simultaneously connected to a Control

Unit via PROFINET, e.g. an automation controller (A-CPU) and a safety controller (F-CPU).

SINAMICS S supports, for this communication, standard telegrams 30 and 31, as well as

Siemens telegrams 901 and 902 for the safety controller.

The following diagram shows the basic structure of this connection version, based on the

example of a CU320-2 PN or CU310-2 PN.
