Log Trigger

  • Last UpdatedNov 03, 2021

The Log Trigger defines the conditions that initiate logging for the group. The Log Trigger options are Always and On Event.

  • If you select Always, logging begins as soon as the run-time Process Log Manager starts.

  • If you select On Event, a True or False Boolean expression is evaluated. If the result of the expression is True, logging occurs.

You define expressions using the Expression Editor. Use the Expression Editor to create a True or False Boolean expression using any of the tags in the process model. For example, a Boolean expression could be a discrete tag. When the tag is True (value of 1), logging for the group begins. When the tag is False (value of 0), logging stops.

For more information on building expressions, see "Expression Editor".
