Historian/VantagePoint - Calculation with PLC tag

[CageFreeBMW]

I have a bunch of tags in Historian/VantagePoint that off by one decimal point. I looked into the HMI displaying the same number, and the HMI is multiplying the PLC tag by 0.1 to get the correct number. Someone has already set up all the links in Historian to the PLC tags so I'm hoping there might be an easy fix.

Is there anyway to add an equation to modify the tag from the PLC in either Historian or VantagePoint?

If I have to, I can add a bunch of rungs/branches to the PLC to create tags with the calculations already done in the PLC. But that, and re-targeting all the Historian tags, will take a lot of work.

VantagePoint has an option for Calculated Tags. You can create one of these and perform the math to get the proper value. Hopefully you don't have too many of these. I don't recall what the limit is for how many Calculated Tags you can have.

Perfect, thank you! I've been searching all day for this. Seemed like a simple issue to solve. I tried so many terms, but "calculated tags" was not among them.
