In the <Trigger Type> group, select the trigger polarity.
: The trigger causes the relay contacts to be open-circuit or drives
the output high, and holds this state for the specified pulse
width.
: The trigger causes the relay contacts to be shorted or drives the
output low, and holds this state for the specified pulse width.
: Each time the trigger occurs, the relay contacts are alternately
closed or opened, or the output is switched between high and
low.
Status: Depending on the status, the relay contacts are closed or opened,
or the output is switched between high and low.
No Operation: The trigger has no effect on the relay state or output level.

In the <Source Device> group, select the control panel or DCU to handle
the GPI output.
SCU1: ID1 control panel (PNL1)
SCU2: ID2 control panel (PNL2)
SCU3: ID3 control panel (PNL3)
DCU1: ID1 DCU
DCU2: ID2 DCU
When the action set in the following step 5 is carried out on the control
panel selected here, this causes a GPI output. It is also possible to output
error information. When the DCU is selected, you can output error
information by means of the action set in step 5.
