I exported tags into csv using Controllogix 5000, but I do not see ranges/0&span (Engineering Units) for analog points. What am I missing? Any related input is greatly appreciated.
Controllogix tags don't generally have range or engineering unit information built into them unless it is a UDT or an AOI
type tag that has been made to have those features. Standard tags just
don't have them.
I found out that ranges are stored on the IO modules, which is not a part of tag export.
What about analog tags that come across Modbus TCP datalink? Where are their ranges defined and how can they be exported?
