I’m using nested UDT’s on my current project and am wondering how to pass the internal udt data type parameters to the external udt.

Any suggestions?

Thanks!

Create a Memory Tag in the UDT and set it’s value to the data type parameter.

So if you have a data type parameter called myStringValue, you add a string memory tag like MyStringValue to the UDT and assign it’s value to {myStringValue}.
