Enable forcing using TESTMODE function block

• 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

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 leave the signals forced, or to revert all of them back to the unforced state.
Commissioning manual
Select the value line of the desired signal, see figure 31.
Press the Enter key to edit the value.
IEC15000021 V1 EN-US
Figure 31: Value line of the desired signal
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).
