PackML Simulator
2 minute read
This microservice is a community contribution and is not part of the main stack of the United Manufacturing Hub, but it is enabled by default.
PackML MQTT Simulator is a virtual line that interfaces using PackML implemented over MQTT. It implements the following PackML State model and communicates over MQTT topics as defined by environmental variables. The simulator can run with either a basic MQTT topic structure or SparkPlugB.

You can read the full documentation on the GitHub repository.
