  • Name
    • A friendly name of the namespace to easily identify it.
  • Subscriptions
    • A comma separated list of subscriptions and supports both the multi-level (#) and single level (+) wild card characters.
    • (+) is a a single level wildcard that matches any name for a specific topic level. This can be used instead of specifying a name for any topic level in the topic filter.

    • (#) is a multi level wildcard that can only be used at the end of the topic filter as the last level and matches any topic whose first levels are the same as the topic levels specified at the left-hand side of the # symbol.


Warning

Check your MQTT Topic subscriptions to verify if they contain valid Ignition tag path or tag name characters. View the Ignition Understand Tag Naming document for details on the tag name rules.

While MQTT and Sparkplug both support characters such as . & % =, Ignition does not support these as valid characters in a tag path or tag name and as a result, it may be necessary to tell MQTT Engine to replace certain characters or strings of characters with something else so the tag path and tag names can be properly created in Ignition. Reference the MQTT Engine String Replacement HowTo for additional details on how to use this configuration.
