Appendix 1 Error Codes
3701H System
consistency
check error
(system
configuration)
• The CPU module model names
differ between the systems A and
B. (The error is detected in the
control system or the standby
system.)
Stop • Mount the same CPU module, and
restart the CPU module.
 At power-on,
at RESET, at
system
switching
execution, at
tracking cable
connection
3702H System
consistency
check error
(system
configuration)
• The number of slots on the main
base unit differs between the
systems A and B. (The error is
detected in the control system or
the standby system.)
Stop • Use the same main base unit (with the
same number of slots), and restart the
CPU module.
 At power-on,
at RESET
3710H System
consistency
check error (SD
memory card
mounting
status)
• The memory card mounting status
differs between the systems A and
B. (The error is detected in the
control system or the standby
system.)
Stop • Match the memory card mounting
status between the systems, and
restart the CPU module.
 At power-on,
at RESET
3711H System
consistency
check error
(memory card
write protect
switch status)
• The write protect switch status of
the memory card differs between
the systems A and B. (The error is
detected in the control system or
the standby system.)
Stop • Match the write protect switch status
between the systems, and restart the
CPU module.
 At power-on,
at RESET
3714H System
consistency
check error (file)
• A file mismatch was detected in
the system consistency check.
(The error is detected in the
standby system.)
Stop • Check the detailed information (drive/
file information) of the error by
executing module diagnostics using
the engineering tool, format the
corresponding drive of the standby
system CPU module, write all files to
the CPU module, and restart the
standby system CPU module. (Set the
same number of steps as that of the
control system CPU module in
"Allocate Memory for Online Program
Change" on the "Program Detail
Setting" window.)
• Execute the memory copy to match
files in the control system and the
standby system. Then, reset the CPU
module of the standby system and run
it again. If the same error code is
displayed again, the possible cause is
a hardware failure of the CPU module.
Please consult your local Mitsubishi
representative.

3730H Redundant
function module
communication
error
• Data communications with the
redundant function module has
failed.
Stop • Check that there is no error in the CPU
module, base unit, or redundant
function module.
• Take measures to reduce noise.
• Reset the CPU module and run it
again. If the same error code is
displayed again, the possible cause is
a hardware failure of the CPU module,
r
edundant function module, or base
unit. Please consult your local
Mitsubishi representative.
