Enable LASTKRUNCHTIMEFROMPACKED

Note: For information on overriding default configuration settings, refer to Modify configuration settings.

The lastKrunchTime field is part of packedRt, and is only updated with packedRt. This means that, if you subscribe to the lastKrunchTime field, it only updates when the analog point's curval field changes.

When you enable LASTKRUNCHTIMEFROMPACKED, then the lastKrunchtime field follows the real lastKrunchTime updates.

The lastKrunchTime field associated with packedRt is called lastKrunchTimeRt. You can subscribe to lastKrunchTimeRt using lastKrunchTimeRt.
