GeoSCADA as MQTT publisher client

[Allan_Blanchard]

Hi,

I'm currently using GeoSCADA and nodered to try out the possibilities of the MQTT protocol for future projects. There are no issues when retrieving data from nodered client to GeoSCADA MQTT client. But I couldn't find any information about how to proceed to publish values with GeoSCADA.

Could you please give me some support on this topic ?

Thank you !

Right now there's no embedded MQTT publisher. There's one coming at the beginning of next year - publishing in Sparkplug payload format.

You could try this: https://github.com/GeoSCADA/Node-Red-GeoSCADA which allows Node-Red to pull/push data - it has not been updated for a while so I don't know if it works still. It's not for the newbie!

What is the current status of the MQTT publisher for Geo SCADA? Is it already available somewhere or is it still being worked on?

It is approaching release soon. We're in Beta test.

Note also - if you have just a few signals to publish, in text or JSON format (ideal for Node-Red), then please use the Geo SCADA MQTT Text driver. Set up points in that driver and configure Control settings to write data to a topic or topics. Then cause any data you want to send to write control values to these points. (What they read back does not matter).
