I have a query and wondered if it can be solved in a real simple manner. For an Energy project I am working on I have created 35 tags although this will increase to thousands in the near future. I would like the combined values of all 35 tags provided in one single tag. My idea when using Excel PI-SMT add in would be to amend the "instrument tag" field with a formula to add all the instrument tags. Alternatively a performance equation would work but this would not be practical when moving to a large number of tags.
I'm new to this so I hope this makes sense, any help / ideas would be greatly appreciated.
