Updating analog alarm thresholds on redundant systems

Update existing alarm thresholds on redundant systems without interruption. You can update analog alarm activation limits and push them to running projects. Some alarm types will have more limits that can be set than others.

Analog alarms are triggered when analog variables change beyond one or more specified limits. Each alarm can be configured in any of the following combinations:

• High and HighHigh alarms: The values reach an atypical high.
• Low and LowLow alarms: The values reach an atypical low.
• Deviation alarms: The values move away from a predefined set point.
• Rate of change alarms: Dramatic value changes occur within a specified period of time.

To update analog alarm thresholds on redundant systems:

1. On the standby server, launch Power Operation Studio.
2. System Model > Alarms tab.
3. From the Alarm type drop-down menu, select Analog Alarms > select the alarm row you want to update.
4. Scroll to the right or use the Properties window on the far right, and then select the High setpoint.
5. Change the setpoint to the desired value for activation.
6. Select Save.
