!!! In order to configure properties of the OPC UA PubSub JSON mapping package, you need to set one or more custom properties on a PubSub connection as follows:
- Property namespace: http://opclabs.com/OpcUA/PubSub
- Property name: Full name of the message channel configuration part type (which is usually the same as the full name of the message channel type itself), followed by "." and the property name from the documentation below. For example, the PubSub connection custom property name for the MqttClientOptions.ProtocolVersion property of the OpcLabs.MqttNet communication package will be "OpcLabs.MqttNet.ManagedMqttClientMessageChannel.MqttClientOptions.ProtocolVersion".
- Property datatype: As given by the documentation below.
- Property value: The desired value.
How this is done depends on the concrete software you are using.

Parameters
Send message mapping
The table below lists the available properties, their types, and descriptions.
