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
