Hello Abul Adnan,

It looks like you got some alarms on your HMI Panel.

Please have a look at the following link:

SIMATIC HMI WinCC flexible 2008 Communication Part 1

See Appendix (9.1) for more information about System Alarms.

Best regards,

Wizard

The main issue is that these events were generated in back dates with following codes and is not going to be acknowledged/reset and displaying on HMI abruptly.

Hello Abul Adnan,

I guess it worked for a long time?

Could it be, someone did try to change a value. And the value that was entered was too high? So it is discarded by PLC.

Hello,

So, these messages are coming back everytime?

Since when does this happen?

Did something change in plc or hmi?

Best regards,

Wizard

Nothing has been changed except the re-commissioning of OP-277 with the old backup program which was done in January 2016 and since then it was running perfectly.

These errors recurred during the previous week. 

Regards.

Hello,

Do you use any scripting in your project?

Perhaps you can check in your project where the tag DB11DW22 is used.

Best regards,

I will check the tag and will update.

Thanks.
