Events
An event is a record of an activity or a condition that is logged in Power Operation. Events are generated by users, the system software, or the connected devices. Examples of events include resetting a measurement, logging into Power Operation, making a configuration change in a device, or a setpoint going active on a device. Some of these events are logged automatically, for others logging must be setup manually. Each event record that is logged has a timestamp and a number of fields that describe the activity. Each event record describes one single activity or condition, for example, a particular setpoint going active in a particular monitoring device.
Events are logged and displayed as they happen in the system without any processing or aggregation. For example, an Over Voltage setpoint going active and then inactive in a device will cause 3 events to be logged, one for the pickup, one for the dropout, and one for the extreme voltage value measured during the time the setpoint was active.
Here is an example of the event records for an over voltage setpoint:
Source | Timestamp | Event | Condition | Measurement | Value | Type |
---|---|---|---|---|---|---|
My.Device | 8/10/2017 1:44:53.000 PM | Over Voltage | ON | Voltage Phase A | 145.740 | Pick up |
My.Device | 8/10/2017 1:44:53.000 PM | Over Voltage | Extreme | Voltage Phase A | 145.740 | Instantaneous |
My.Device | 8/10/2017 1:45:39.000 PM | Over Voltage | OFF | Voltage Phase A | 125.230 | Drop out |
Power Operation uses event records to determine alarm types and states.
