Triggered latch
The Triggered latch computed channel generates an output channel that latches the previous input channel data value when triggered.
- Name: Enter a name for the channel. The name must be unique and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<' and '>'). Invalid channel names are 'true' and 'false' (case sensitive).
- Collect: Select the Collect checkbox to write the channel data to the SIE data file during a test run.
- Description: Enter an optional detailed description of the computed channel.
- Input channel with sample rate: Set the desired input channel. In the edit dialog, the channel sample rate is displayed in Hz.
Trigger
- 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.
