Current alarms

Click the Browse button (...) to select which graphic display is used to show alarm messages when an alarm is triggered.

Edit

Click this button to open and modify the selected graphic display.

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 run time, 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 run time, 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

Specify the maximum amount of alarm entries in the log file. The available value is 1-10,000.

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.

The available value is 1-99.

A write connection. Click the Browse button to assign a tag to the connection to notify the data source that the amount of alarm entries received has reached or exceeded the capacity high warning threshold.

Capacity high-high warning (%)

Specify the threshold of capacity high-high warning, which will occur when the amount of alarm entries reaches or exceeds the specified percentage of the Maximum number of alarm entries.

The available value is 1-99 and must be greater than the Capacity high warning value.

A write connection. Click the Browse button to assign a tag to the connection to notify the data source that the amount of alarm entries received has reached or exceeded the capacity high-high warning threshold.

Capacity overrun

Specify when the amount of alarm entries received exceeds the Maximum number of alarm entries and the oldest entry is overwritten.

A write connection. Click the Browse button to assign a tag to this connection to notify the data source that the amount of alarm entries received has exceeded 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.
