When enabled, this flag indicates that the physical datapoint is decoupled from the
datapoint, e.g. in case of manual override for inputs. The present value displayed is
not the present value, which would be delivered by the physical input.
NOTE: Multiple flag indications may be possible.
Example: A ´To-Fault transition` will also always enable the ´In Alarm` flag. Hence
both, the ´In Alarm` and the ´Fault` status flags are enabled.
Alarm Buffer and Alarm Display For the various datapoints, different triggering criteria must be fulfilled before an
event is generated and reported (intrinsic reporting criteria). If all criteria are fulfilled,
the event/alarm is generated and displayed in the alarm list. Depending on the
datapoint type, the following three event types are described:
Datapoint type Event triggering criteria (intrinsic reporting criteria) Event type
Binary Input
Binary Value
Multi-state Input
Multi-state Value
If present value changes to a new state for longer than the time delay
AND the new transition is enabled in the event transitions options for
reporting CHANGE OF STATE
Analog Input
Analog Output
Analog Value
Pulse Converter
If present value exceeds range between high limit and low limit for
longer tha time delay AND the new transition is enabled in the event
transitions options for reporting and if high or low limit enable options
are enabled
OR
Present value returns within the high limit - deadband to low Limit +
deadband range for longer tha time delay AND the new transition is
enabled in the event transitions options for reporting and if high or low
limit enable options are enabled
OUT OF RANGE
Binary Output
Multi-state Output
If present value differs from feedback value for longer tha time delay
AND the new transition is enabled in the event transitions options for
reporting
NOTE: ´Feedback` value will be supported in a future
version of Excel Web
COMMAND FAILURE
Suppress Alarm Generation If the alarm delay is set to 100,000 seconds or higher, the alarm will be suppressed.
The ´In Alarm´ flag and the ´State` will not change, even if the alarm conditions are
reached. If the point is already in alarm state (Off-Normal) and the ´In Alarm` flag is
set and the alarm delay is changed to 100,000 seconds or higher, the state of the
point is set to ´Normal`.
Only the alarm conditions can be disabled with the alarm delay of 100,000 seconds
or higher.
The fault condition cannot be disabled with alarm delay.
Start Alarm Time The start alarm time is the time during which the notification of alarms is
suppressed. The start alarm time will become effective upon every start/restart of
the Excel Web controller, e.g. power-on, application start, etc. Entering a start alarm
time is requested to prevent alarm shower at start/restart of the controller.
If alarms are still active after the start alarm time has elapsed, these alarms will be
notified as usual.
Alarm Delay Besides the datapoint´s specific alarm values, e.g. high and low limit of an analog
input, the alarm delay is important for the alarm behavior of all datapoint types.
The alarm delay determines how long a ´To-Off-Normal` or ´To-Normal transition`
must exist before an alarm is generated.
