(2) Clearing event history
(3) Storing event history data
(a) Auto-save feature
When the serial number (first five digits) of the master/local module is "12072" or later, 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.
