The TagsActive Input tag will change from 1001 to 0 because all points are
taken off of the scan. This is the number of tags that have been created in the
FactoryTalk Historian ME with scan set to ON.
2. Enter “1” in the StartDataCollection Value field and click [ENTER]. The
following occurs:

TagsActive will increase to 1001.

DataCollectionActive will change to 1.

DataCollectionRate, DataTransferRate, and ArchiveRate will update.
You can write Ladder logic programs to monitor these statistics and
programmatically start and stop Data Collection and/or stop and start batches
depending on the status of the module. You must write Ladder logic (or manually set
tags to 0) to reset the Output tags back to 0.
This concludes the sample scenario demonstrating how to use AOP with your
FactoryTalk Historian ME.
