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 PC’s time information can be read and used in the Controller Link Unit.
When the time cannot be read from the PC, all error log times will but 0.
This can occur for PC startup errors, Unit No. errors, CPU Unit errors, or
PC 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/CJ-series PCs, 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 PCs 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.
