Alarm Management

Settings

Some alarm server functions are based on changed tag values:

Alarm function Description

Remote acknowledge Performs remote acknowledge of all current alarms when the tag value is 1

Clear alarms Removes all alarms from the alarm server when the tag value is 1

Enable/disable alarms Enables the alarm server when the tag value is 1

Show Alarm Indicator

Select for which alarm statuses the alarm indicator is to be displayed.

Log Settings

Parameter

Max Number of Logged

Rows

Description

The maximum number of alarms to save in the database. If the number of collected items becomes larger than the set value, the oldest item will be deleted. The value must be within the size of the available amount of memory in the operator panel in runtime.

Repeat Counter

To avoid that an alarm that is triggered repeatedly results in multiple entries in the alarm list,

Repeat Count

can be used. The current alarm will then only appear once in the alarm list, and number of times the alarm is triggered will be included in the alarm text. For display in the Alarm Viewer and for logging, select whether to show the time of the first or last occurrence of the alarm.

Alarm Server Events and Actions

Actions can be configured for the entire alarm server. One or multiple actions can be configured when a particular alarm server event occurs.

Select

Actions

in the Alarm Server properties page to configure actions for the alarm server.

Actions for the following alarm server events can be configured:

Alarm Acknowledge

The specified actions will be triggered once for every alarm that is acknowledged.

The actions will be applied for the individual alarm first. If no action is specified for the alarm, the actions will be applied for the group. If no action is specified for the group, the actions will be applied for the alarm server.

Normal and Alarm Inactive, but not Alarm Deleted.

The specified actions will be triggered once when the status of several alarms change at one occasion. A collection of alarms is returned.
