The IO-FEP2 provides an internal event log which records all changes at input circuits, waveguide switch or output circuit actuations and temperature / supply limit alarms. Each event is stored with a time stamp read from the IO-FEP2's real time clock.
The event log is organized as a set of eight files which are written in a round-robin manner. Every time the IO-FEP2 boots or after 24 hours a new file is started. If a USB stick is plugged into the IO-FEP2 and 'Use USB Stick' at the 'Setup-General' page is set to YES, the event log is permanently stored on this device. Otherwise the files are stored in volatile memory and are lost when the IO-FEP2 is switched off.
