Hello to all.
I got a simple task (as I thought) - show user and machine name, when someone change dpe value.
But as I can see, there is no _alert_class, that can show this info everytime value changes.
How can I show user and machine names on dpe value change? Maybe without using dpConnect - functions.

Re: How to make alarm text message on value change?
In WinCC OA you have to differ between value changes and alerts.
Do you want to show this information if a value is changed or if an alert is raised?
Shall it be made everytime when a value is changed or only in special cases?
By default the user ID (not the name) is written to the attribute _original.._user if an original value is changed.
If you want to save information for special commands you can probably use the Audit Trail functionality of WinCC OA. For detailed information please search for "Audit Trail" in the WinCC OA documentation.
