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.
(1) The PLC's time information can be read and used in the SYSMAC LINK
Unit. When the time cannot be read from the PLC, all error log times will
be set to 0. This can occur for PLC startup errors, unit number errors,
CPU Unit errors, or PLC model errors. When error logs without times are
read from the CX-Net, 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 cor-
rectly.
(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 in-
formation will be all zeros in the year 2000 if it is read from Support Soft-
ware.
The following table lists the error codes (in 4-digit hexadecimal) and the con-
tents of the errors.
