Actual and history event-alarm

[Marco_C]

Hello everyone,
I'm new to using node-red. I come from the plc-hmi world.
I explain my problem.
At home I installed a plc that manages part of home automation, I use node-red on a raspberry that reads variables and also creates graphics, sends telegram messages, emails.
All this is already done and operational.

I stopped in wanting to create, as in the operator panels, the list of current alarms and alarm history.
I set up a csv with the various alarms, I send a word with the active alarms but I don't know how to manage it to display the string associated with the incoming alarm.

Thanks to everyone who help me

HI and welcome to the magic world of Node-Red.

Though I don't use CSV files, this is what I use:

Press the GENERATE button and get a result.
If there is a list shown, it wipes and refreshes the list.
To clear you have to double press the WIPE button. (Not shown)

This is the flow (picture first)

Basically it generates a list from reading the file and spits it into an array on the screen.

Extra nodes needed:

node-red-contrib-ring-buffer
node-red-contrib-fan (though you can just get rid of this node.) I use it to help make flows neater.

You will have to edit some parts of the flow (and maybe some global values.)
But I think mostly the exec node.

Sorry for the brief reply, but I hope you can see your way to getting it working.

[Marco_C]

Thank you i'll try. and i hope

[dathor]

depending on your web knowledge you may also want to take a look at 'uibuilder' to display active alarms and alarm history in separate tables.

[Marco_C]

I had a sample of code that i use...........right but not practical to use. Do you know a better way?

This is my solution whit infinity word of alarm. it works fine for me
