We can Import new Pipeline list & its Properties from Excel using tag instances. But we cannot overwrite the existing values. We can export these values ( Attributes of Valves etc... ) through explorer, details items, and can be edited one by one in the details items window and it is accepting these changes. Insted we need a function to import these values and do a constitency check and overwrite these valves. This will help to import the p&Id data ( in excel format) from other tools like COMOS etc to Openplant.
