The label of the corresponding frame/GPIO card/output pin is displayed here
for reference.
Label A label may be assigned to the GP output here as described in
Source Defines where the control signal to the GP output comes from: Local Source
(i.e. from within the same system), Net Source (from a networked system,
if available), or '–' (nothing).
In case the Level input signal should not be available, a replacement value
may be entered here (low or high).
Time Defines the duration of the pulse at the output pin. Time is only relevant if
Triggered Edge is falling or rising.
Possible values are 0 ms or 40 ms to 1 s, in 20 ms steps.
Polarity Defines the polarity of the output pin signal: Active high is positive, active
low is negative polarity.
Defines which edge of the Level input signal causes the output to change:
falling, rising, or both.
Used to activate/deactivate an output pin. The Level input signal used as input
Activate
to the GP output only changes if Activate is On.
On power up, the output is initialized according to the Level input signal.
Notes:
Time, Polarity, and Triggered Edge must not be changed while the GP
output is active.
Important! For correct take-over after a modification, it is important to select Activate
to On, because it is automatically set to Off when a modification is made.
