9.8.4.1
Undo forcing by using TESTMODE component
GUID-CA5CCA57-DFFF-4362-AC1D-08738D2BA45F v2
•
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.
9.8.4.2
Undo forcing by using LHMI
GUID-55199606-E70D-49B1-885D-251700FB562B v1
•
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.
9.8.4.3
Undo forcing by using PCM600
GUID-CE7FD186-99FC-41C8-910F-894A57037777 v2
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.
If the IED is left in test mode, then it is still possible to perform new forcing
operations, both from LHMI and from PCM600
