The signal “freezes” and will not change value even if, for example, a binary inputsignal voltage changes level, or if a binary output is activated as the result of aprotection function block activating.12.8.3.2 Forcing by using PCM600 GUID-E9D0DAE6-7A86-4FF9-943E-42039015D05B v1In PCM600 the concept is a bit different compared to LHMI. The forcing isaccomplished by entering a forcing session. Within such a session, multiple signals onmultiple I/O boards may be edited and changed at the same time and has no effect onthe IED. Once the user is satisfied with the forcing setup, then all the changes can beeffectuated simultaneously towards the IED, potentially changing inputs and outputson multiple I/O boards at the same time. It is also possible to abort this operation(described in step 6 below) and to undo all forcing.1. Right click on the IED in the plant structure and select Signal Monitoring.2.
