Alarm management in SIMATIC PCS 7 – Smart Alarm Hiding

  • Entry
  • Associated product(s)
With the Smart Alarm Hiding, alarms of a process tag can be filtered or hidden depending on the plant state. A big advantage of this method is that the filtered and hidden alarms are still processed and archived in the alarm system of the OS.

With the previous alarm suppression (Lock / Suppress) in SIMATIC PCS 7, the alarms at the process tag are suppressed. This means that messages from a process tag do not reach the alarm system of the PCS 7 OS and are not displayed and archived on the OS.

In this documentation we show you how to project Smart Alarm Hiding and use them in your project.
This makes possible for you, that the message volume in process mode can therefore be reduced and the handling for the plant operator can be improved. There are two kinds to implement Smart Alarm Hiding:

  • Manual Alarm Hiding
  • Automatic Alarm Hiding
