Event logging

Events produced by the meter’s various ION modules are prioritized and grouped to facilitate custom logging. Each event is assigned a priority group number based on its type and severity.

Event priority groups

Some event groups are preset with a priority number as shown in the table below. You can also define your own priority number for some modules. Priority numbers from 128- 191 appear in the global event log viewer in the Vista component of Power Monitoring Expert. Priority numbers from 192-255 are also logged, initiate a beep and cause the window to flash. You can customize these responses to display messages or perform netsend messages, for example.

Event group	Description	Priority number
Reset	Module reset or re-synchronized	5
Setup Change	Module setup changes (setup register changes, label changes, input handle changes)	10
Input Register Change	Inputs of certain modules change value (for example, input to And/Or module changes)	15
I/O State Change	I/O state changes (for example, relay closes)	20
Information	Module produces important user information	25
Warning	Module produces a warning	30
EN50160 Event (ION8650A and ION8650B only)	An EN50160 counter (N1or N2) increases	50
Loss of Potential	Loss of Potential has occurred	128
Error Detected	An error has been detected	255
Setpoint	Setpoint condition goes Active or Inactive (for example, Sag/Swell module detects a disturbance)	programmable via module setup

The Event Log Controller module allows you to set a priority cutoff for event logging. Any events with a priority number greater than the cutoff value are logged, and events with lower priorities are discarded. Refer to the individual module descriptions and the Event Log Controller module description in the ION Reference for more details.

Events external to the module

Some events are not produced by a specific module. These events are generated internally by the meter. Their associated priority levels are shown in the table below.

Event group	Description	Priority number
Warning	Factory initialize performed	30
	Firmware or memory upgrade performed
	Meter power-up or power-down
	Internal modem not responding or modem recovered
	Battery low
	Serial terminal locked out
	Security disabled or enabled
Failure	Communications not able to allocate required memory	255

User triggered events

When a user produces an event, such as a reset, successful or unsuccessful login attempts, user lockout or setup change, the event log displays the username associated with the event. Events created in basic security through the front panel have the username USER0. Events created in advanced security through the front panel or ION Setup are associated with the username that was logged into the meter (USER1 - USER50).
