Triggered Latch

The Triggered Latch computed channel generates an output channel that latches the previous input channel data value when triggered.

ClosedCommon Parameters

Select the trigger Channel to use to trigger the data latch.

By default, the channel latches the input data value when the trigger channel transitions from FALSE to TRUE and holds this data value until the trigger channel transitions from TRUE to FALSE. When the trigger channel is FALSE, the channel outputs the same value as the input channel.

NOTE
If the trigger channel is initially TRUE, the channel outputs a system defined value of zero until the trigger channel transitions to FALSE.

Select the Invert option to reverse the logic of the trigger.
