Audible Interrupt Signaling; Time Stamp - Siemens SIMATIC PCS 7 Configuration Manual

10.3.6

Audible interrupt signaling

Process failures and errors can be indicated by audible signals, as well as output in the
message list. The signal is issued by means of a signal module or active loudspeaker by
outputting a multimedia (Wave) file via the computer's sound card.
Note
Information on the function and installation of signal modules can be found in the "Process
Control System PCS 7 WinCC Basic Process Control"
cs/ww/en/view/1400148) manual.
The WinCC editor "Horn" offers a multitude of options (e.g., message classes, origin, areas,
event, priorities) to trigger different acoustic signals. A corresponding variable (of the "Horn"
group) must be created for this.
Note
You will find further information on configuring the "Horn" editor in the FAQ "How do you
configure the horn in SIMATIC PCS 7?"

Time stamp

Messages are generated in different areas and at various positions within PCS 7. The origin
of the message will, therefore, affect its time stamp.
All messages are archived and are displayed in the same way, regardless of their origin. AS
and I/O messages are forwarded to the OS servers separately via the plant bus. They already
contain the appropriate time stamp. The OS server arranges all messages in the correct order.
To ensure that the correct time stamp is always available, you must configure time
synchronization between all the components of the PCS 7 project.
