An operating mode is internally changed at the end of a PLC cycle.
Attention
If outputs are set when switching over the operating mode switch from RUN
to STOP, they remain set! Switching off the software side i.e. by initiators,
are ineffective, because the program is no longer processed.
Note
With "GET_STOP_VALUE" (library "System.lib") WAGO-I/O-PRO 32
provides a function which serves to recognize the last cycle prior to a pro-
gram stop giving the user the possibility to program the behavior of the con-
troller in case of a STOP. With the aid of this function the controller outputs
can be switched to a safe condition.
