WebVisu AlarmGroup requires Clean or full download to Update

[bclapperton]

I'm using the Codesys Alarm Management system. When I add or change an alarm group message text is not updated until I do a Clean or do a full download and restart. Is this normal Codesys behaviour? Or something to do with ctrlX implementation of codesys.

Is there a way to update the table without doing a full download?

Start Situation

Change Message

Login the the PLC with Online change. The message still says "Hello". I tried rebooting the PLC but still no change. I tried deactivating and reactivating the alarm but the message does not change. I tried Reset Cold and Build-Generate code. 

When I do a Build->Clean, or a Reset Original and download and start the PLC it changes.

I'm not familiar with the CoDeSys Alarm Manager, but I expect it works similar to other systems. Therfore I found thing article:

Thanks @HmiGuide, However, I can clear and re-trigger errors, but the text does not change until I do a download.

Basically, there is no technical reason why this should not be updated with OC (onlinechange).
It just hasn't been implemented yet.
So at the moment there is only the workaround with the full download to use.

We are working on a solution and will try to integrate it into one of the next visualisation add-on versions.

Hi,

I face same issue so if it could be updated soon it would be great!

Can I have two more questions regarding alarm group:

- If you delete some msgs, the IDs are also deleted and never re-sorted. Is there function to re-number ID from 1 and keep incrementing by 1 till end? We have alarm management where my array index corresponds to msg and if some IDs missing it´s difficult to assign correct msg and latch variables.

- Is there any chance to implement feature that Latch variables of numeric data type (e.g. Int, word) could be represented by Text list as well? It´s quite common in other HMI sw and it would make creation of msgs much easier.

Thanks a lot.
