3RM13 reversing starter with PLC control, F-DO pp-switching

As an alternative to the 3SK1 safety relay, 3RM11/3RM13 Failsafe motor starters can be
controlled by an F-DO module. In this typical circuit, shutdown is realized by a pp-switching
F-DO module in 1 channel.
Up to SILCL 3 in accordance with EN 62061, PL e/Cat. 4 in accordance with
EN ISO 13849-1 can be achieved. To this end, the controlling outputs must also fulfill
SILCL3 in accordance with EN 62061/PL e/Cat. 4 in accordance with EN ISO 13849-1.
Note
SILCL 3 in accordance with EN 62061, PL e/Cat. 4 in accordance with EN ISO 13849-1
SILCL 3 in accordance with EN 62061, PL e/Cat. 4 in accordance with EN ISO 13849-1 can
be achieved by laying the control lines from the safe output to IN1 and IN2 of the 3RM1
motor starter in such a way that they are protected against a cross-circuit/line-to-line fault,
e.g. as separately sheathed cable or by laying in separate cable ducts.
This application is available for S7-300, ET 200M, ET 200MP and MSS 3RK3. This
application is not available for ET 200S.
