Retrieve UDT Structure
« on: July 06, 2016, 10:24:42 AM »
Hello,

Is it possible to retrieve the UDT structures from a CLX? Or the plc only stores the tag name and the structure become a byte structure, which can be interpreted only by the programming IDE?

I searched a lot in the forum about my question i couldn't find an answer.

Thank you!

Ramon.

The AdvancedHMI driver does not support retrieving a UDT structure definition. If you read a UDT, it will return a string of encoded bytes that you can then extract and reconstruct the data. In the following thread, I posted a function that shows an example of extracting the data:
