[Alarms status table] Alarms stuck

Ignition
,
1

Hello there,
we are having problems with Alarms that gets stuck into Alarms status table.

Due to the factory's power flickering (they are obviously trying to fix this) because of some problems into the current cabinet, looks like Alarm tags are unable to "feel" the tag change event and clear the alarm message.

If we search those tags into the tag provider in ignition (and also into PLC), those bits are False and should not display the alarm message.

I found out that the only way that i have to let the tag refresh and read the true value is by refreshing the tag provider they are in or disabling/enabling tags.

Maybe there is a way to "force a refresh" of the alarms or the provider with a script? I tried to figure it out by myself but without success and...there i am.

Can anyone help me?

Thanks in advance.
N.

Ignition version: v8.0.17

You should be able to right click the tag and restart that individual tag, though I'm not sure if that would remove the alarm as well, but it will get the latest tag reading.

For flickering issues like this you probably want to configure an Active Delay on the tags alarm.

Thanks for the reply.

The fact is that i'm looking for a way to restart/refresh without having the Designer opened all the time.
Something like a button that can be pressed by a maintainer (higher privilege) that unlocks this situation could be good.

There maybe a better option out there, one thing you could test is using:
https://docs.inductiveautomation.com/display/DOC81/system.tag.requestGroupExecution

This should cause your entire tag group to execute now, so will cause them all to poll the PLC for values.

I've only really used for slowly polling tags, where I want them to update right now. Not sure how much on effect it would have on a tag that updates quickly anyway

Thanks.

I'm sorry, didn't see this function on system.tag.

I'll try and let you know if it works.
