You can create templates that point indirectly to a set of tags based on a simple parameter. This is very helpful when you have a large number of UDTs with the same type of tags that only differ in one parameter. For example, lets say you have 100 Motor UDTs that all have the same kind and number of tags. The only thing that is different is the Motor number.

If each tag inside the UDT has a tag path that looks like this:

You can create a Template Paramenter property on the Custom Properties window and make it to point to one of the tags indirectly, for example, you can call it motorNumber.

For every component within the template the tag path can be bound with indirection in such a way that the Custom property of MotorNumber substitutes the motor number therefore resulting in a valid tag path that points to the desired motor.
