I have a PE Tag clock scheduled (1 min 5 sec). Am using two Tags(A & B) in the Equation where the Time Stamp should be captured on any of the Tags have a value change.
My PE Tag is working as expected but the issue is the Trigger Tag (A) writes in a Duplicate value of the Existing value just 2 sec or some times 1 sec before the new value is updated.
Time stamps and value marked in bold letters in the below example:
0 - 06-07-2018 00:01:00
0 - 06-07-2018 00:02:00
1 - 06-07-2018 00:02:02
1 - 06-07-2018 00:02:03
2 - 06-07-2018 00:02:04
The trigger Tag is configured float and the Instrument tag is of type VT_UI2.
The key settings of the trigger Tag is
Excdev - 0.005
Excmax - 10 minutes
compdev - 0.01
compmax - 8 hours
Appreciate if some one can provide a reason for this extra data record in the archive, while am also trying to figure out the logic that is configured on the Source system?
