MQTT BIRTH - Creating Ignition Folders

[chrisgray]

Just wondering what syntax is required to create additional folders within the DBIRTH Topic in NodeRed. We have some NodeRed nodes that are communicating to the Ignition Distributor where we would like to have additional subfolders created. You cannot use the “/” in the Topic: deviceId /DBIRTH which builds the root folder of any data set. Does anyone out there know the trick to creating a subfolder in Ignition? (The Ignition Engine & Transmission module does this naturally, but there is some method to passing the entire Folder structure through MQTT).

MQTT BIRTH - Setting Ignition Tag Properties

Just wondering if anyone knows how to set the Tag Properties in Ignition from the NBIRTH or DBIRTH message_type elements (or other method)? I have an EoN device that is not Ignition (NodeRed - using Sparkplug node), but would like to send up some information to Ignition to provide more Meta data about the Tag. Example might be to add some description to the Documentation property of the Tag or Units of Measure (Engineering Units). [image]
