2.12 Mode selector switch
The mode selector switch is used to define the operating state of the standard controller.
The mode selector switch does not influence the operating state of the safety-related
PROFINET controller (SPNS).
The RUN/PROG and STP (STOP) positions have a toggle button function, and the MRESET
position has a pushbutton function. After the switch has been released in the MRESET posi-
tion, it returns to the STOP position.

WARNING: PROFIsafe process data exchange inter-
rupted
If the operating mode switch is in the STOP position, process
data between F-Host and F-Devices is not exchanged in the
network via PROFIsafe. The F-Devices assume the safe
state (failure state) after the defined watchdog time has
expired.
