PROFINET with 2 controllers

11.3.7.1

Control Unit settings

Note
Operation with two controllers is only possible in conjunction with an F-CPU.
SINAMICS S120 allows 2 controllers 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 the PROFIsafe standard telegrams 30 and 31,
as well as the Siemens telegrams 901, 902 and 903 for the safety controller.
Example
The following diagram shows a configuration example of a drive with three axes. The A-CPU
sends Siemens telegram 105 for axis 1 and Siemens telegram 102 for axis 2. The F-CPU
sends PROFIsafe telegram 30 for axis 1 and axis 3.
