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:
--- Clears the event log.
--- Jumps to the oldest entries in the log
--- Goes one page back to older entries
--- Goes one page forward, to more recent entries
--- Jumps to the mots recent entries in the log.The display of the event log does not automatically update if new events are added, use the browser's reload button or
to see if new events have been added.
