When publishing to MQTT (RBE, Sparkplug, JSON), data values are published with corresponding tag name, if configured in ACE, with some exceptions (substitutions) noted below.
With MQ-RBE, Sparkplug-B, or MQ-JSON:
- If tag name includes a space, the space will be converted to an underscore _ character instead.
- The space-to-underscore conversion also applies to the Ethernet/IP master protocol.
With MQ-RBE or Sparkplug-B (not JSON):
- If tagname tag name includes a period period . it it's tag will be published with a forward slash / instead.
- If tagname tag name includes an integer between square brackets for an array (such as [1123] ), it's tag will be published with the integer surrounded by forward slash and underscore instead (such as /1123_ ).
...
- In Ignition, the forward slash in a published tag name creates a level in the collapsible tag hierarchy.
