Error Log Section 10-3
Error Log Table Configuration
Time Information
The time is recorded in BCD with one byte each for the year (the rightmost
two digits), month, day, hour, seconds, and minutes of the time the error
occurred.
Note 1. The PLC’s time information can be read and used in the Controller Link
Unit. When the time cannot be read from the PLC, all error log times will
but 0. This can occur for PLC startup errors, Unit No. errors, CPU Unit er-
rors, or PLC model errors. When error logs like these are read from the
Controller Link Support Software, they will be dated 0 s, 0 min, 0 hr, 0 day,
0 month, 2000.
2. When replacing the battery for CS-series PLCs, it will be necessary to
switch the power supply ON and reset the internal clock.
If the internal clock is not reset, time information in the error log will not be
recorded correctly.
3. The time information will be all zeros for CQM1H-series PLCs unless a
Memory Cassette with a clock is mounted in the CPU Unit. The time infor-
mation will be all zeros in the year 2000 if it is read from Support Software.
4. When Controller Link Units are used in duplex operation, if there is an ac-
tive/standby switchover resulting from an error in a Unit, the error log is not
inherited from one Controller Link Unit to another. To save the error log,
use this command or the Programming Device to read the error log as ap-
propriate.
