Tag Historian , Keep Duplicate values

I am logging machine cycle times using the historian. I have the historian set up to log on change. However, I also need to collect successive duplicate values (e.g. 65,64,67,67,66,67). Currently, the historian is filtering these out. Is there a way turn that feature off? I need the successive values to make my statistics work out. If I need to abandon the historian and use the Bridge then that’s ok.

Well, logging “on change” when the value doesn’t change doesn’t make a lot of sense. (-:
What you are after is to log “previous cycle duration” when the cycle is complete. The Bridge can do this – trigger on one item to record something else (or several somethings). Consider using a cycle odometer as your “on change” trigger in a Transaction Group.
