Specifying the communication package

In order to select this communication package in OPC UA PubSub tools, you need to set a custom property on a PubSub connection as follows:

  • Property namespace: http://opclabs.com/OpcUA/PubSub
  • Property name: MessageChannel!
  • Property datatype: String
  • Property value: OpcLabs.Mqtt.MqttClientMessageChannel,OpcLabs.Mqtt

How this is done depends on the concrete software you are using.
