Parameters > Citect.ini File Parameters > Alarm Parameters > [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 CitectSCADA 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.

Allowable Values: 0 to 10000 (milliseconds)

Default Value: 1000
