So i recently been getting a system alarm (ID: 536871427) TimeCorrectionAlarm.

Alarm text: Computer1 ("PC_NAME): Partner requires time correction.

It occurs frequently, every 15 minutes or so. (I bellieve it started after update to WinCC Unified V18.1 (Not sure))

Currently using a S7 315 plc but it have also occurred on 1511 CPU. 

I have set PLC time from PC, but alarm still occurs.

Any idea how to get rid of this? Some kind of setting in Unified?

Hi all,

Since V18, Update 1 is a fairly recent release, this message may be a bug. So it might help to create a new support request.

Kind regards
Stefan

Hi,

I had the same problem and find a way to fix it.

1. Go to the Alarm control en set the "Time zone" Property. Mine was 110.

2. Download project

3. Probably it won't work. Go to the Alarm control en set the "Time zone" Property back to -1 and download again.

4. The alarm should now be gone.

Hopefully this helps for you too,

Thanks for the feedback. Will try this.

At the moment i have filtered out this alarm so it is not shown in alarm control and also not registered as a new or pending alarm. This also works fine.

Hopefully this will be solved in next update from Siemens

Hello, as an alternative solution, the message ID with the static value ID<>53.7526277 can also be hidden under the settings of the message window under the item General >> Filter.

This is only a workaround.
