Function
The corresponding bit will be ON when
the built-in RS-232C port is communi-
cating with NT Link mode or Serial PLC
Link mode.
Bits 0 to 7 correspond to Units 0 to 7.
Indicates (in binary) the number of
bytes of data received when the built-in
RS-232C port is in no-protocol mode.
The corresponding bit will be ON when
the Serial Option port is communicat-
ing with NT link mode.
Bits 0 to 7 correspond to Units 0 to 7.
Indicates (in binary) the number of
bytes of data received when the Serial
Option port is in no-protocol mode.
When a non-fatal error (user-defined
FALS or system error) or a fatal error
(user-defined FALS or system error)
occurs, the 4-digit hexadecimal error
code is written to this word.
Note When two or more errors occur
simultaneously, the highest error
code will be recorded.
ON when a fatal error that is not
defined for A401.01 to A401.15 occurs.
Detailed information is output to the
bits of A314.
Note There are no errors that affect
this flag at this time. This flag is
reserved by the system.
ON when a fatal error is generated by
the FALS instruction. The CPU Unit will
stop operating and the ERR/ALM indi-
cator will light.
The corresponding error code will be
written to A400. Error codes C101 to
C2FF correspond to FALS numbers
001 to 511.
Note This flag will be turned OFF when
the FALS errors are cleared.
ON if the cycle time exceeds the maxi-
mum cycle time set in the PLC Setup
(the cycle time monitoring time). CPU
Unit operation will stop and the
ERR/ALM indicator on the front of the
CPU Unit will light.
Note This flag will be turned OFF when
the error is cleared.
