Parameter One of the following
backup problems was detected
data (flash during a cold start with
memory) the CS1W-LCB01/05 or
error a cold or hot start with
the CS1D-CPU@@P.
1) The data was cor-
rupted by noise or other
factor.
2) The power was inter-
rupted during a backup.
(See note.)
3) The power was inter-
rupted during duplex ini-

The configuration of error log data including error codes is as follows. Error
log data is stored in RAM (battery-backed up) on the Loop Controller. The
configuration of each error log is as follows and is regarded as a single record.
Error log data is not stored in flash memory.
RAM can hold up to 256 of the latest records:
1 record Error code
Detailed information
Date (year/month) and time (hour/minute/second) of occurrence
Error log data can be read using the FINS (READ ERROR LOG, [command
