● Assisted Treatment. If an operating procedure was configured for a particular
alarm, the icon in the event button indicates that you can open a dedicated
window, with the alarm’s event descriptor displayed along the top, that provides
a step-by-step checklist of actions you must complete for handling that alarm.
For example, these might include printing out a report, completing a form,
reading a document, and so on. At the same time, you can send alarm-
handling commands from the event descriptor at the top of the window, just as
you would from inside Event List.
For instructions see Handling an Event with Assisted Treatment [➙ 72].
Simultaneous Handling of Events by Different Operators
A Desigo CC installation can have one or more client stations from which operators
monitor and respond to alarms.
● At any given time, you can see which operators and stations are handling an
event. This information is available in the event button tooltip and in the In
Process by column of the event descriptor.
● Even if an event is being handled by another operator/station, you can still also
handle the same event from your own station, using any of the available
methods. The only limitation is that:
– If another operator/station is handling an event using Assisted Treatment,
you cannot also initiate Assisted Treatment for that event.
– However, you can still start Investigative Treatment, or send alarm-handling
commands from within Event List.
The system continually updates the list of users who are handling the same event,
and removes any users who are disconnected for any reason.
Visibility of Alarms in the System
The specific events visible to you depend on your user access rights. This means
that the Summary bar, Event Detail bar, and the Event List, Investigative
Treatment, and Assisted Treatment windows display only the alarms coming from
the points that you are allowed to see in System Browser . If an alarm is generated
by a point not visible to you in System Browser, it does not display on your
management station.
Validation for Event Handling
Validation might be required for commanding events. This means when an event
occurs in order to be able to send alarm handling commands, the operator will be
asked to provide a comment (Validation Profile = Enabled) or a comment and a
password (Validation Profile = Supervised).
The alarm handling comment that explains the reason for the action is recorded
and stored in the Detail Log tab.
Auto-Event Handling
Desigo CC can be configured to automatically start the alarm handling of certain
events when specified conditions occur on the site. In this case, certain actions
such as opening Event List or selecting the event might happen automatically, so
you will not need to do them manually. For more information, see Event Settings
for Event Treatment Reference.
Activity Log and Event Log
During event treatment, entries are recorded in the History Database for the
following:
