Analyzing Events
Event Reporting
Event Summaries
For every triggered event, the device generates and stores an event summary. The
device stores the most recent 17 (if event report length setting LER := 15) or 4 (if
LER := 64) event summaries. When the device stores a new event summary, it
discards the oldest event and event summary if the event memory is full. The
example event summary in Figure 9.1 shows the available information.
The device sends event summaries to all serial ports with setting AUTO := Y
each time an event triggers.
With optional currents and/or voltages installed, the current and/or voltage fields
will display the magnitudes shown below at the instant the ER equation asserted.
