Triggered latch

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

ClosedGeneric parameters

  • Name: Enter a name for the channel. The name must be unique and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<', '>').
  • Collect: If selected, the channel data is written to the SIE data file during a test run.
  • Input channel: Set the desired input channel. In the edit dialog, the channel sample rate is displayed in Hz.
  • Channel: Set the trigger channel used to latch input channel data. 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.

  • Invert: If selected, the output logic is inverted. The channel latches the input data value when the trigger channel transitions from TRUE to FALSE and holds this data value until the trigger channel transitions from FALSE to TRUE.
