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.
