Expanded functionality with WinCC Runtime Professional
Alarms can occur via the derivation of the individual bits of a PowerTag (max. 32), as a result of a chronological message frame directly from the automation system, as a result of analog alarms due to any number of limit value violations, or due to an operation In doing so, hysteresis values can be set and ranges can be monitored easily
Since the alarm structure is freely definable, it can be tailored to the special requirements of a plant. Dividing the structure into as many as 10 different text blocks (plant ID, fault location, text, etc.) leads to greater clarity of the information and allows targeted analyses to be initiated in connection with the filtering or sorting function. Differentiation of as many as 16 alarm classes permits the separate preparation of alarms, warnings, faults and errors for several areas of the plant. Within an alarm class (e.g. warning), up to 16 priorities can also be differentiated.
Based on the contents of the individual alarm blocks, filtering, selecting and sorting is possible in the screen, e.g. chronologically, according to priorities or fault location. Then the contents can be exported directly as a CSV file or printed out as a report. A freely definable toolbar function also provides a high degree of flexibility. In this way, for example, your own project-specific functions can be integrated. To maintain a clear overview of a large number of incoming alarms, the operator can suppress unimportant operational messages on the screen display by means of Alarm Hiding. The alarms continue to be logged in the background.
The Microsoft SQL Server is used for logging of alarms. This ensures gap-free recording of all events. Alarms are logged when alarm events occur. In the alarm sequence report, the alarms can be (selectively) chronologically documented. In the alarm log report, specific views of the logged alarms can be generated.
