UDT Organization

There are various UDT organization techniques you can use, but here is the one I personally prefer. Essentiallyt the top level is the OPC-UA server name (Ignition, KepServer, etc), the first child is the device driver (Logix, Modbus, etc), then finally the company who the UDT is based on (Integrator Name, or "Native" for native tag types in the device). Here's an example using our company name (ICS) (Bolded items are folders):

    • Parents
      • OPCParent
