We're using an Ignition Edge in combination with the Cirrus Link MQTT Transmission to transfer our tags & UDTs over MQTT to our Ignition server. However, we have a problem with transferring the UDT parameters. In the Ignition Edge, we have a UDT called "Test" with 2 parameters, as can be seen below: ![Screenshot 2025-03-25 084655](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/5/6536b3386d6770ef55a13e05396b2a6556cd7a63.png) In the Ignition server, we receive this "Test" UDT, but none of the parameters are present here: ![Screenshot 2025-03-25 085011](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/c/4cef770e15863d62548cfbd34d62534a99eca68c.png) As for the MQTT Transmission Transmitters settings, the settings for UDT are configured as follows: ![Screenshot 2025-03-25 085207](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/c/fccc77316b9489bc28c88ae14feb3f500f212023.png) ---

Hi Stijn, Did you publish the UDT to the Ignition gateway first without parameters? This means the parameters were not present in the BIRTH message. If you change something in the UDT structure you've to republish this by setting the "Transmission Control/Refresh" to "TRUE".
