I have two different tags to depict the open state and closed state of a valve. Is there any other method other than using PE tags in Processbook by which i can map these two instrument tags to a single symbol in the processbook screen.
You can use AF formula attribute or analysis to calculate your state from two different tags.
After creating the attribute, you can specify it from PI ProcessBook's multi-state symbol.
Or you can use dataset to calculate the results from multiple tag values.
PI ProcessBook > Tools > Data Sets
Remember that the dataset's minimum calculation interval is 1 minute.
I recommend AF to calculate it.
