Hello, I'm using Engine to read a topic from a Broker, then I apply a UDT and send it back to the broker using Transmitter to get the messages in SparkplugB. This works correctly if Engine is reading up to a certain number of messages simultaneously. If, for example, there are 60 messages in the broker, Engine moves this information to Ignition, but Transmitter sends this information without the UDT/SparkplugB. Any idea what might be happening? Thanks ---

Please explain a bit more what you're trying to do with more detail. ---

We'll need to see your Transmission configuration to see how you have it set up.
