Hello Everyone,

I am new in Ignition and I am testing the MQTT module because I am using MQTT protocol to send the data of my devices, so I see as soon as a message arrives this creates a new tag with the value of the message, the message contains data from different sensors and i am separating this data in a script, the problem I have is that I want to configure alarms for each of the variables that I am separating in the script, but from what I have learned to configure the alarms i should have a tag for variable and I’m talking about 20 variables per device and I have 10 devices, is there any way to do this differently? sorry for my english.

I appreciate all the support you can give me

I haven’t worked with MQTT yet, so I’m not sure if there’s a better way to do that end of it. Others may have better suggestions.

[system.tag.addTag](https://docs.inductiveautomation.com/display/DOC79/system.tag.addTag) is an efficient way create a bunch of similar tags (run it from script console or elsewhere, depending on needs).

You can use [system.tag.writeAll](https://docs.inductiveautomation.com/display/DOC79/system.tag.writeAll) to write the values to all the tags in one call.

So you have to configure a second tag for any points that you want alarming on with MQTT? that seems inconvenient.

No. The OP is packing multiple actual values into a single MQTT "value". The split up values need to be in their own tags to be alarmable. I'd change the system to report each actual value individually -- it's really hard to get any gain from report-by-exception using an aggregate.
