Status logging

Data link status of all stations is logged. If multiple stations repeatedly fail and recover or stations following a specific
station do so, the location of the error cause, such as poor cable connection and noise, can be easily identified.
With "RAM + Flash ROM" selected, the first 45 logs after logging start are stored on the flash ROM. Logs stored on the
flash ROM can be checked even after the system is powered off and on or the CPU module is reset.
