You’re correct the payload may be getting set as an active payload, but when you run your program to query with get\_target\_payload() it will pull from the installation file.

I know that the primary and secondary client stream the TCP offsets, so you can parse through the stream as shown here: [How to process package from robot controller - #4 by ajp](https://forum.universal-robots.com/t/how-to-process-package-from-robot-controller/390/4)

Unfortunately there currently isn’t any built in method for reading the active payload as you described.

You can also try setting the payload in a thread on polyscope instead, the thread could get updated from a variables passed in using a RTDE interface, or other external sources. When the payload is set in the same program that is querying the target payload, you will read the active payload.
