MQTT V3 Plug-in Reference

"extractorLibraryName"

• String
• Optional
• Defaults to "ctMQTTJson".

It specifies the extraction library that parses and extracts MQTT messages for Persistence Topics.

By default, MQTT messages are assumed to be JSON documents. You can specify other extractor libraries to parse and process XML and other formats.

Possible values:

• "ctMQTTJson" processes messages as JSON documents.
• "ctMQTTXml" processes messages as XML documents.
• "ctMQTTCognex" processes messages as Cognex XML documents.

Note: The core settings are the same across all extractors, but each extractor may have a few unique settings. Unless otherwise noted in this documentation, a setting applies to all extractors.
