I have a program that reads data from an OPCUA server and creates tags depending on how many machines are connected to the OPCUA server, so if there are 3 computers, then 3 folders with a bunch of tags are created at the start of the program. Currently I have the values of the tags being set to labels with a timer, but I would prefer to use Tag Change event, but because I don’t know how many computers will be connected, I can’t just set a bunch of tags before runtime. Is there a way to either dynamically add more tags to trigger a Tag Change, or to tell it to trigger any tags in a specific folder? Thanks in advance.
