Example of LHMI menu using BIM3
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
