Handling the Interlocks and Manual Control in the Manual Mode
In S7-Graph, the sequencer controls the functions for the automatic mode. The
functions for the manual mode required over and above those of the automatic
mode are included in a separate FB. Using action bits (for example Carr_fwd) the
sequencer is connected to the interlock and manual control.

The permanent monitoring functions required for the units can be programmed with
S7 PDIAG. Depending on the requirements, the supervision conditions can be
formulated so that they are effective both in the automatic and manual modes or
specific supervision conditions are programmed for the automatic mode and for the
manual mode.
