Remote Operation
:OPEN
Example Query ROUTE:PFAil:OPEN? (@101,205);
The inclusion of a question mark causes a readback of the power up state of
the requested channels as a list of 1s and 0s separated by commas.
❍ A 1 means the channel is in the PFA:OPEN list.
❍ A 0 means that it is not.
When querying the PFAIL state, the PFA:CLOS list must be checked as well
to determine whether the power up state for a given channel is programmed
at all.
If a relay is in neither the PFAil:OPEN or PFAil:CLOS lists, its power up
state is determined by the last save stored to EEROM for that relay.
The query form is not available when using a path name, due to the potential
for confusion between the first group and the second in the path.
