Hello 🙂

I'm simulating a CNC machine with by creating an OPCUA device. Now I'd like to connect it with the MQTT Transmission Module to send the data to a MQTT broker. Do you know if this is possible?

Thanks in regards!

Hi @user1998,

As long as your simulator has tags, they should be able to be sent via MQTT. Once those tags are defined in Ignition, this documentation from Cirrus Link, who makes the Transmission Module, details how to get those tags configured in the MQTT Transmitter:
