Time settings
Specify notification hold time, maximum update rate, and embedded server update rate in this area.
Hold time
Select the notification hold time (millisecond) to use when acknowledging, silencing, and resetting alarms. The application holds values at the Ack, Silence, Status Reset, and Close Display connections for the specified length of time, then resets the connections to zero.
Maximum update rate
Select the maximum rate (second) at which data servers will supply data to the trigger tags specified on the
Triggers
tab. The default update rate is 1 second.
This rate also applies to any tags used in trigger expressions, remote tags or expressions, and tags in trigger message embedded variables.
At runtime, all of these tags are updated immediately upon startup, no matter what the update rate is.
Embedded server update rate
Select the embedded server update rate (second) at which the data server will supply data to the tags in the trigger message embedded variables. The default update rate is set to match the alarm update rate.
The embedded server update rate cannot be set to be larger than the maximum update rate.
At runtime, all of these tags are updated immediately upon startup, no matter what the update rate is.
History
Specify the alarm log file (.alm).
Maximum number of alarm entries

If the amount of alarm entries in the log file reaches the maximum capacity, the oldest alarm entry is deleted when new alarm occurs.
Capacity high warning (%)
Specify the threshold of capacity high warning, which will occur when the amount of alarm entries reaches or exceeds the specified percentage of the
Maximum number of alarm entries
.

Optional connections
Specify the following optional connections:
  • Silence - A write connection. If alarms use the audio signal, assign a digital tag to this connection to notify the data source that alarms have been silenced.
  • Remote Silence - A read connection. Assign an analog tag or an expression to this connection. When this connection changes to a new non-zero value, all alarms are silenced. Alarms can be silenced using other methods regardless of this connection’s value.
  • Remote Ack All - A read connection. Assign an analog tag to this connection. When this connection changes to a new non-zero value, all alarms are acknowledged.
  • Status Reset - A write connection. Assign a digital tag to this connection to notify the data source that the alarm status has been reset, that is, the accumulated time for all alarms has been reset to 00:00:00, and the alarm quantity for all alarms has been reset to 0.
  • Remote Status Reset - A read connection. Assign a tag or expression to this connection. When this connection changes to a new non-zero value, the alarm status is reset. All accumulated alarm times are reset to 00:00:00, and all alarm quantities are reset to 0. If an alarm is still active when the alarm status is reset, its accumulated time will continue from 00:00:00 and its alarm quantity will increase from 0 to 1.
  • Close Display - A write connection. Assign a write connection. Assign a digital tag to this connection to notify the data source that the pop-up alarm display has been closed.
  • Remote Close Display - A read connection. Assign a tag or expression to this connection. When this connection changes to a new non-zero value, the pop-up alarm display specified on the
    Advanced
     tab of the
    Alarm Setup
     editor is closed.
  • Remote Clear History - A read connection. Assign a tag or an expression to this connection to allow the data source to remove all alarms from the alarm log file and alarm lists, and reset the alarm status.
