Improved message filter in the acoustic alarm
As of WinCC V7.4, you can specify the user text blocks as filter for triggering the signal in
addition to the message class and the message priority.
By default, the first three user text blocks of a message are available with the following default
setting:
● WinCC project:
– Message text
– Point of error
– Block: 3
● PCS 7 project:
– Source
– Area
– Event
You can optionally use the other user text blocks.
You can configure the filters for each user text block dependent on the language or language-
neutral.
Cancellation filter
To negate a filter, use the following prefix:
● !
The corresponding tag is then only triggered of the filter with this prefix is not applicable.

Status of the redundancy synchronization
The redundancy monitoring points to a redundancy synchronization that is running:
Arrow symbols signal that a redundancy server pair is currently performing a synchronization.
SIMATIC Process Historian-Server
When you use the SIMATIC Process Historian, the status of the Process Historian system is
checked as well.
For the status monitoring of master (principal) and standby (mirror), WinCC uses the following
system tags:
● @PHServer_Principal_State
● @PHServer_Principal_Details
● @PHServer_Mirror_State
● @PHServer_Mirror_Details
