[MAIN CPU DOWN]
Runaway or failure of the remote I/O module
• Malfunction due to noise or other causes
• Hardware failure
Collateral information
• Common Information (SD5 to SD15): -
• Individual Information (SD16 to SD26): -

• Hardware failure
Collateral information
• Common Information (SD5 to SD15): -
• Individual Information (SD16 to SD26): -
Diagnostic Timing
• Always
• Take noise reduction measures.
• Reset the remote I/O module.
If the same error code is displayed again, the cause
is a hardware failure of the remote I/O module.
(Please consult your local Mitsubishi representative.)
REM: Off

Remote I/O status: Stop
1009
[MAIN CPU DOWN]
• The voltage waveform that is outside the specification is
applied to the power supply module, and an error is
detected.
• A failure was detected on the power supply module,
remote I/O module, main base unit, or extension cable.
• When using the redundant base unit, the redundant power
supply module failure in both systems is detected.
Collateral information
• Common Information (SD5 to SD15): -
• Individual Information (SD16 to SD26): -
Diagnostic Timing
• Always
• Correct the voltage waveform applied to the power
supply module.
• Reset the remote I/O module.
If the same error code is displayed again, the cause
is a hardware failure of the remote I/O module.
(Please consult your local Mitsubishi representative.)
REM: Off
ERR: On
Remote I/O status: Stop
1109
[RAM ERROR]
The work area RAM in the remote I/O module is faulty.
Collateral information
• Common Information (SD5 to SD15): -
• Individual Information (SD16 to SD26): -
Diagnostic Timing
• Always
The cause is a hardware failure of the remote I/O
module. (Please consult your local Mitsubishi
representative.)
REM: Off

1300
[FUSE BREAK OFF]
There is an output module with a blown fuse.
Collateral information
• Common Information (SD5 to SD15): Network No./Station
No.
• Individual Information (SD16 to SD26): -
Diagnostic Timing
• Always
Check the FUSE. LED of the output modules and
replace the module whose LED is on. (A blown fuse
can be identified using GX Works2 or GX Developer.
Check the special register, SD1300 to SD1331, to see
if the bit corresponding to the module with a blown fuse
is set to "1".)

[SP.UNIT DOWN]
• There was no response from the intelligent function
module in the initial processing.
• The size of the buffer memory of the intelligent function
module is invalid.
• The unsupported module is mounted.
Collateral information
• Common Information (SD5 to SD15): Module No.
• Individual Information (SD16 to SD26): -
Diagnostic Timing
• At power-on/At reset

/When intelligent function module is
accessed
If an unsupported module is mounted, remove it. When
only supported modules are mounted, the cause is a
hardware failure of the intelligent function module,
remote I/O module, or base unit. (Please consult your
local Mitsubishi representative.)
