A400 All Error code When a non-fatal error
(user-defined FALS(006) or sys-
tem error) or a fatal error
(user-defined FALS(007) or sys-
tem error) occurs, the 4-digit
hexadecimal error code is written
to this word. When two or more
errors occur simultaneously, the
highest error code will be re-
corded.
Refer to the CS/CJ Series Op-
eration Manual for details on error

FALS numbers 001 to 511.
This flag will be turned OFF when
the FALS errors are cleared.
