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
1. Right click on the IED in the plant structure and select Signal Monitoring.
2. Click on the List View tab.
3. Click Forcing Session in the menu IED/Start Forcing.

The Signal Monitoring menu changes and indicates the forcing values that
can be edited.
