When the forcing is removed by exiting from IED test mode, both
input and output signals may change values. This means that logic
input signals may activate functions in the IED and that output
relays may change state, which can be potentially dangerous.

Undo forcing by using TESTMODE component

• If the IED test mode was entered through the test mode function block:
1. Deactivate the control input on that block.
This immediately undoes all forcing, regardless of how it was accomplished
and disabled all the way to force signals.

Undo forcing by using LHMI

• If the IED test mode was enabled to using the LHMI:
1. Set IEDTestMode to Off in the LHMI menu.
2. Exit from the menu and click Yes in the Save dialogue box.
This immediately undoes all forcing, regardless of how it was accomplished
and disabled.

Undo forcing by using PCM600

1. Uncheck Forcing Session under the menu IED.
IEC15000031 V1 EN-US
2. Click Yes in the confirmation dialogue box.
PCM600 will revert all forced signals back to unforced and the real signal
values will immediately take effect again.
This may change both binary input values and output relay states
and will undo any forcing done by using the LHMI.
