How to change binary input/output signals using forcing

Once the IED is in IED test mode, the LHMI/PCM600 menus can be used to control input/output
signals freely.

Forcing by using LHMI

Editing a signal value directly
• Edit the input/output value directly to select the desired logical level, by doing following:
1.
2.
3.
When navigating away from a LHMI forcing menu for an I/O board, the user is prompted to either

Use the up/down arrows on the LHMI to change the signal value or the appropriate menu
in PCM600.
The status of the signal changes automatically to Forced (i.e. there is no need to set the
status to Forced manually).
On the LHMI, these edit changes have immediate effect. This means that the value
changes directly when the up/down arrow is pressed (i.e. there is no need to press
the Enter key to effectuate the change).
