[Alarm]Active

The period (in milliseconds) at which the clients are advised of a change in alarms. For example, if [Alarm]Active is set to 1000, the Control Clients are advised every 1 second (if a change has occurred in the alarms held on the Alarms Server).

If you are communicating from a Plant SCADA client to the Alarm Server over a slow serial or Wide Area Network (WAN) link, you might want to increase the value of this parameter. This would use less network bandwidth and increase the overall performance of your system.

Note: This parameter can also be applied to a specific cluster or alarm server process. For more information, see Configure Alarm Parameters for a Specific Cluster or Process.

Allowable Values:

0 to 10000 (milliseconds)

Default Value:

1000
