Hello, I am using Allen Bradley MicroLogix PLC and there’s an integer array is designed for 5 tags inside it named as N7:0, N7:1,…, N7:4 Now, I want to create a Master UDT for a tank, which has parameter TowerNumber. The Tank UDT will have 5 instances based on TankNumber, however, they should also include the atomic tags inside the N7 folder. For example, Tank 1 will corresponds to N7:0, Tank 2 will corresponds to N7:1, and so on. The problem I’m facing is when adding the paths from OPC Browser, I want to create a dynamic path for the UDT so that when the instances of the UDT are created, the elements inside the N7 folder can be referenced to their respective Tanks. ---

This looks awful familiar… I’m going to refer you to the [documentation](https://docs.inductiveautomation.com/display/DOC80/UDT+Definitions#UDTDefinitions-AddingParameters). Pay attention to the way parameters are referenced in the examples on that page. Hope this helps!
