WinCC Alarms Stike Through

Hi all,

Has anybody experienced this/or has a fix.

PCS7 V8.1 wincc 7.3 +upd10

I'm unable to remove wincc alarms, they are acknowledged with a strike through them. This has only happened during a recent power outage on plant, coupled with an unexpected UPS failure.

I have seen a fix for PCS7 V9, but not V8.1

Thank Grif

Dear grifasp,

it will eventually disappear when the alarm is triggered again. There is a post talking about this previously. I have attached the link here for your reference. 

Strikethrough Messages

There is a siemens post talking about this too. 

Entry type: FAQ Entry ID: 15186316 , Entry date: 01/25/2008(1) rate Why are the time stamps of messages struck through or replaced by asterisks in PCS 7?

Hope it helps.

Hello grifasp,

unfortunately I have to tell you, that there is no solution for PCS 7 8.2 or lower Version to acknowledged with a strike through, which can't acknowledged.

Only with WinCC V7.4 SP1 (compatibility with PCS 7 V9.0) Siemens made some change in the software to delete theses messages.

With regards
Heisenberg
