Sparkplug B Device Emulation

Prerequisites:

• Installing the Java Runtime Environment
• Installing Ignition
• Installing the following MQTT Modules
  • MQTT Distributor
    • v3.1.0 or greater if using Ignition 7.9.X
  • MQTT Engine
    • v3.1.0 or greater if using Ignition 7.9.X
• Downloading the Sparkplug Sample Code onto a development system

Overview:

Sparkplug is an open source project developed by Cirrus Link Solutions which shows how devices or projects can be enabled to communicate with MQTT Engine and Ignition.  These examples will show how data can be published via MQTT from an emulated device running on a development machine.  In addition, it will show how devices or applications can be controlled by writing to tags in Ignition.  It will also show the caveats associated with establishing/ending an MQTT session and ensuring that the tag values in Ignition are valid.

Programming Language Variations:

• B: Example C Client
• B: Example Java Client
• B: Example JavaScript Client
• B: Example Node-RED Client
• B: Example Python Client
