Status Logging - Mitsubishi LJ61BT11 User Manual

15.4.3 Status logging

15 - 38
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.
(1) Operating procedure
1) In GX Works2, select [Diagnostics] and then [CC-Link Diagnostics] and
double-click the "Status Logging" icon.
2) Select the log storage area.
Select either of "RAM" or "RAM + Flash ROM".
If GX Works2 cannot be connected continuously, select "RAM + Flash
ROM". The logs (max. 45) stored in the flash ROM can be confirmed by
connecting GX Works2 after the log collection.
If GX Works2 can be connected continuously, the maximum of 5000
logs can be collected for either "RAM" or "RAM + Flash ROM".
