(3) Storing event history data
(a) Auto-save feature
Event history data is automatically saved on the flash ROM. For this reason, the
saved event history data will not be erased by resetting the CPU module or
powering off and on the system.
REMARK
• Auto-save may fail if performed between the time that the CPU module is reset or
the system is powered off and on and initial processing is completed. If failed, the
event, "Invalid event history data." is displayed in "Event history contents".
• Events that have occurred during one second before the CPU module is reset or
the system is powered off are not saved to event history.
(b) Storing event history data in a CSV file
Event history data can be stored in a CSV file.
1) Click the [Create CSV File...] button in the "Network Event History" window
and save the event history data in a CSV file
