I’m runnign 7.9.10 with the Cirus Link MQTT modules. Right now I have a single MASTER group that all of my MQTT tags get assigned to.

How many GROUPS can I setup in Ignition 7.9.10?

Thanks, I will - but is it not a setup parameter in Ignition that actually controls the MQTT Groups?  
It reads as if I can have several I just would like to know if Ignition has a Limit. See Example:

That’s all from the MQTT modules, so Cirrus Link would be in the best position to answer.

FWIW, here is a link to Cirrus Link’s MQTT Engine docs for their 7.9 series of modules: [ME: Configuration - MQTT Modules for Ignition 7.x - Confluence](https://docs.chariot.io/display/CLD79/ME:+Configuration)
