Status Logging - Mitsubishi Electric L26CPU-BT User Manual

Status logging

This function logs the data link status of all stations. When multiple stations, such as stations of a specific station
number and higher, repeatedly fail and recover, the cause and location of the problem (e.g. poor cable contact or
noise) can be identified easily.
If "RAM + Flash ROM" is selected, the first 45 logs after starting logging are stored to the flash ROM. The logs stored
to the flash ROM can be checked after turning off and on the power or after resetting the programmable controller
CPU.
