Figure 21: 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).
