I am new to ignition so please bear with me!
I have created a UDT tag called pump and in that tag I have 3 integers which connect to the PLC via OPC. The three values makeup the data that is associated with my pump. So far so good. Now I want to make the OPC path dynamic so that if my OPC path changes I just modify the address in one place and all the tags change. But I can’t seem to be able to point a parameter of my UDT at an existing tag, in this case my default tag would be a string containing the address of the OPC server and the instances of my UDT’s would then reference this address.
I hope that makes sense and thanks for your help.
