The signal "freezes" and will not change value even if, for example, a binary input signal voltage
changes level, or if a binary output is activated as the result of a protection function block
activating.

Forcing by using PCM600

In PCM600 the concept is a bit different compared to LHMI.The forcing is accomplished by
entering a forcing session. Within such a session, multiple signals on multiple I/O boards may
be edited and changed at the same time and has no effect on the IED. Once the user is
satisfied with the forcing setup, then all the changes can be effectuated simultaneously
towards the IED, potentially changing inputs and outputs on multiple I/O boards at the same
time. It is also possible to abort this operation (described in step 6 below) and to
forcing.
