SIMATIC PCS 7 process control system

Message view of operator station
SFC visualization
SFC visualization
The SFC visualization function of the operator system enables
display and operation of the sequential controls configured
with the SFC editor in the same way as on the engineering system.
No additional configuration work is necessary.
In an overview display it is possible, for example, to open step
and transition displays and to present step comments or dynamically
supplied step enabling conditions.
Messages and alarms
Message priorities are issued as an additional attribute to the
known signal classes in order to make it easier to assess large
quantities of signals and to be better able to distinguish important
messages from the less important.
Operators can specifically disable messages (alarms) from individual
process tags or from all process tags of a display/area
in the event of faults in a sensor/actuator or during startup.
Disabling and enabling are recorded in an input report.
Active messages are signaled by group displays representing
preconfigured views based on signal groups. The group displays
also indicate whether messages are disabled or not.
The last message to have arrived – or the message with the
highest priority when alarm priorities are utilized – is displayed
at the top edge of the standard view. A predefined
window with further messages can be called up with the
"Extended message line" button.
The "Loop-in-alarm" and "Select display using process tag"
functions support the quick evaluation and elimination of
faults. Using "Loop-in-alarm“, the operator can jump directly
to the process display in which the fault has occurred, and can
then call up the associated faceplate (loop display) through a
measuring point marked in color.
The faceplate window (loop display) can be anchored using a
pin button so that it remains visible even when the display is
changed.
Flexible sound setting options and priorities which can be defined
using signal variables support audible annunciation
through a soundcard or by controlling external horns via a signal
module.
Central user management, access control and
electronic signature
SIMATIC Logon offers central user administration with access
control for the SIMATIC PCS 7 system components as well as
non-SIMATIC components connected through API. It can be
used to fulfill the validation requirements of 21 CFR Part 11.
An electronic signature function can also be used in conjunction
with SIMATIC Logon.
A chip card reader can be additionally used for access control.
