Enable forcing using TESTMODE function block
GUID-DD17B7D6-516F-4561-9D30-906B968EAFE0 v1
•
Use the TESTMODE function block, appropriately configured in PCM600/ACT.
It may be convenient to control the input on mentioned component from, for example, an LHMI
function key or similar during commissioning to quickly and easily enter IED test mode.

How to change binary input/output signals using forcing
GUID-7DF9FAF1-68B1-49AF-9DE4-2A8D6F6FAEFE v1
Once the IED is in IED test mode, the LHMI/PCM600 menus can be used to control input/
output signals freely.

Editing a signal value directly
GUID-E0C115BE-3AD1-48C7-BA2D-29857CD3D3ED v1
•
Edit the input/output value directly to select the desired logical level, by doing following:
1.
Select the value line of the desired signal, see figure
.
2.
Press the Enter key to edit the value.

Figure 31: Value line of the desired signal
3.
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).
When navigating away from a LHMI forcing menu for an I/O board, the user is prompted to
either leave the signals forced, or to revert all of them back to the unforced state.
