Details
The maximum of 16 types of error codes are stored into 'Self-diagnostic error
number' (SD10) onwards when the diagnostics detects an error. (The same error
code as one already stored in 'Self-diagnostic error number' (SD10) onwards is not
stored). The 17th error code onwards are not stored. Also error codes are not stored
when 16 types of error codes have already been stored into 'Self-diagnostic error
number' (SD10) to 'Self-diagnostic error number' (SD25).
The value of this register increments by one and stored as a BIN code, each time
input voltage drops to 85% (AC power)/65% (DC power) or less of the nominal value
while the remote head module is carrying out an operation. A counting cycle from 0
to 65535 to 0 is repeated.
The lowest number of module in which a fuse blew is stored.
The lowest I/O number of the module which has an error detected by the I/O module
verification is stored.
