Hi All

I have a unistream 10.4" PLC+HMI.

I am using program version 1.28.34

I am using the built in alarm function and also using the alarm history.

The problem is that when an alarm occurs it does not always get added to the top of the alarm history list.

I have set the view to default by date.

I am using the date format dd/mm/yy

If i get a new alarm it sometimes appears on top of the list or sometimes if I scroll down it will be in the middle of the alarm history.

Does anyone know if this is a known issue with this program version. I dont want to upgrade unless I have to.

I also considered clearing all alarms and alarm history as something may have been corrupted during project development.

Is there a way to completely wipe the alarm history?

Any advise would be appreciated.

Regards

Denis

Hi Denis,

I have the same problem.

I already did a post last week about this, but no reply on it until now.

I am using the same programm version 1.28.34.

At the alarm summary the list is well right sorted at date/time.

By using the alarm history it seems to be that it is sorted only at time and no date is used.

So it seems to be that it is a bug in the software. 

I check at the newest version the upgrade items on the list, but did not find that this isue is solved.

So hopefully Unitronics read this at will fix this bug.

Regards,

Leen

Hi Alex

Thanks for your reply.

The unit is on site and has been running for a year.

This is the only issue I can see.

I dont like upgrading the software on a unit that is working unless I have a good reason to do so.

It is difficult to get downtime on the machine and they normally give me a very small window for modifications.

Do you know if this is a known issue with 1.28.34  that has been solved with later versions?

Also is there any way to completely wipe the alarm history?

Regards

Denis

Issue "Alarm 'dateTime' sort is by text and not by date" resolved from version 29 and above.

Thanks NoamM

I will upgrade to the latest version the next time I am on site.

I can see the "clear alarms" bit in "ACTIONS" but this only clears all active alarms.

Is there a bit I can set to clear the alarm history?

Normally after commissioning and testing a system I have many alarms that I have tested.

I dont want the customer to see these alarms or he will think the unit has had major problems.

Forget the second part - i found the location of the clear button in the properties window.

Regards

Denis
