I have renamed a few tags and they are in trends in Excel and I was wondering if the tags in the trend should update automatically like they do in ProcessBook. For ProcessBook 3.0.15 and newer there is a procbook.ini file where you can specify if the tag updates based on tagname or pointid. Is there a similar datalink.ini file where you can specify the the tag updates?
No. PI Datalink does not use the PointID - so you will have to change the name manually. As an alternative you may use the Point ID to Tag function to retrieve the name of a Tag based on the Point ID and reference this result in your trend. This would require that you initially find out the Point ID and use that additional step for your spreadsheets.
However, installation problems and end-user type of questions should be addressed to the tech support team (firstname.lastname@example.org).
