3.11 Event Log

The IO-FEP provides an internal event log which records all changes at input circuits, waveguide switch or output circuit actuations and temperature limit alarms. Each event is stored with a time stamp read from the IO-FEP's real time clock. The event log is limited to a size of 500 event, the log works as a circular buffer, recent entries automatically overwrite the oldest ones. The event log resides in the IO-FEP's volatile memory, the log always starts empty when the IO-FEP is powered on.

The event log page shows up 25 entries from the event log in a table. Initially the 25 recent entries of the log are shown. Five buttons above the event log table control the display of the log:

The display of the event log does not automatically update if new events are added, use the browser's reload button or last.gif to see if new events have been added.
