is it possible to get a list of tags that are on a PI ProcessBook graphic?
You can use the ProcessBook Support Tool to complete this task. You should be able to download it here.
If you cannot see the link then you may need to contact tech support to get access.
One way I fetch the tags is by clicking the 'Explore in Coresight' button and exporting the data from Coresight display
The tag list should be in the exported XML file. The trick is to make sure the time duration in Coresight is set to 1 minute or so that way the generated XML file is small enough.
Not sure exactly on how you would like to consume the list, but there is a built-in functionality to get the points in a display using the "Status" icon at the bottom of the screen. It normally shows up as a green circle or a red circle with an 'x'. Double-clicking this will open a report on all the points within the display, which you can save to a file.
