Acknowledgement of WinCC V7 Messages with Forced Comments
In this context it is to be understood what user has acknowledged a message when and why. This information is to be displayed and archived in the control system.
The application example expands the message function of WinCC by an additional acknowledgement function with comment. These additional comments are mandatory, they have to be used. It is not possible to acknowledge the messages with out a comment.
Not all messages have to be acknowledged with comment. They are defined through a certain message class.
If a message is acknowledged with mandatory comment, an additional dialog (WinCC picture window) appears first. In this dialog box, the comment is assigned.
Through an additionally generated operator message, the comment is stored in the message archive. The correlation between message and operator message can be made through date, time and message text. User and comment are also stored in the operator message.
