Triggered Pulse Output

The Triggered Pulse Output feature allows an output point to generate a precise timed output pulse when triggered by a local input point. When you configure the output, select a local input that acts as a trigger.

You can control the output pulse timing using the following parameters:

Pulse Delay (in seconds)
: Defines the delay after the input transition before the output pulse starts.
You can configure this parameter using the output tag
O.Outputxx.PulseDelay
. The valid value range is (1 ms + Input Filter Time)…30 s.
Pulse Active Time (in seconds)
: Specifies how long the output pulse remains active once triggered after pulse delay.
You can configure this parameter using the output tag
Outputxx.PulseActiveTime
. The valid value range is 10 µs…30 s.

A rising edge or falling edge of the input signal can initiate the trigger. To initiate the trigger on the falling edge, enable the Invert Trigger option. You can also use the output tag

O.Outputxx.Trigger

to trigger the pulse on its rising edge.

If a triggering transition occurs while the current output pulse is already active or in the delay period (waiting), the new trigger is ignored and

I.Outputxx.TriggerMissed

bit is set to indicate that a trigger event was missed. You can use the

O.Outputxx.ResetTriggerMissed

bit to reset the

I.Outputxx.TriggerMissed

bit.
