12.1 Error Code List
12.1.3 Error code list (1000 to 1999)
1401
[SP. UNIT DOWN]
• There was no response from the intelligent
function module/special function module in the
initial processing.
• The size of the buffer memory of the intelligent
function module/special function module is
invalid.
• The unsupported module is mounted.
■Collateral information
• Common Information:Module No.(Slot No.)
• Individual Information:–
■Diagnostic Timing
• At power ON/ At reset/When intelligent function
module is accessed
When the unsupported module is mounted, remove
it.
When the corresponding module is supported, this
suggests the intelligent function module/special
function module, CPU module and/or base unit is
expecting a hardware fault (Contact your local
Mitsubishi representative.)

1402
[SP. UNIT DOWN]
The intelligent function module/special function
module was accessed in the program, but there
was no response.
■Collateral information
• Common Information:Module No. (Slot No.)
• Individual Information:Program error location
■Diagnostic Timing
• When an intelligent function module access
instruction is executed
This suggests the intelligient function module/
special function module , CPU module and/or base
unit is expecting a hardware fault (Contact your
local Mitsubishi representative.)
1403
[SP. UNIT DOWN]
• The unsupported module is mounted.
■Collateral information
• Common Information:Module No. (Slot No.)
• Individual Information:–
■Diagnostic Timing
• When an END instruction executed
When the unsupported module is mounted, remove
it.
When the corresponding module is supported, this
suggests the intelligent function module/special
function module , CPU module and/or base unit is
expecting a hardware fault (Contact your local
Mitsubishi representative.)
[SP. UNIT DOWN]
• There was no response from the intelligent
function module/special function module when
the END instruction is executed.
• An error is detected at the intelligent function
module/special function module.
• The I/O module (intelligent function module/
special function module) is nearly removed,
completely removed, or mounted during running.
■Collateral information
• Common Information:Module No. (Slot No.)
• Individual Information:–
■Diagnostic Timing
•Always
The CPU module, base module and/or the
intelligent function module/special function module
that was accessed is experiencing a hardware
fault. (Contact your local Mitsubishi representative.)
1411
[CONTROL-BUS. ERR.]
When performing a parameter I/O allocation the
intelligent function module/special function module
could not be accessed during initial
communications.
(On error occurring, the head I/O number of the
corresponding intelligent function module/special
function module is stored in the common
information.)
■Collateral information
• Common Information:Module No. (Slot No.)
• Individual Information:–
■Diagnostic Timing
• At power ON/ At reset
Reset the CPU module and RUN it again. If the
same error is displayed again, the intelligent
function module/special function module, CPU
module or base unit is faulty. (Contact your local
Mitsubishi representative.)
