Control Unit settings

Note
Operation with two controllers is only possible in conjunction with an F-CPU.
SINAMICS S120 allows two control systems to be connected simultaneously 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, PROFIsafe 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.
