Appendix 1 Error Codes
Error details and cause
• An invalid power supply module
has been mounted on the
redundant power supply base unit.
• A power supply module other than
the redundant power supply
module has been mounted on the
redundant power supply base unit.
■CPU module
• The number of writes to the flash
ROM (data memory, program
memory, and system memory
(memory used by the system
when the CPU module executes
its function)) exceeded 100000
times.
• Files are frequently written by the
event history function.
■SIL2 function module, safety
function module
• The number of writes to the flash
ROM exceeded 100000 times.
(Number of writes > 100000)
• The voltage of the battery built in
the CPU module has dropped
below the specified value.
• The connector of the battery built
in the CPU module is
disconnected.
• The connector of the battery built
in the CPU module is not securely
connected.
• Data cannot be written to the
memory card because the write
protect switch is locked.
• Time setting has failed when the
CPU module is powered on or
reset.
• The default gateway is not set
correctly.
• The gateway IP address is not set
correctly.
• The default gateway/gateway IP
address (network address after
the subnet mask) is different from
that of the IP address of the own
node.
• The port number is incorrect.
• The port number setting of the
external device is incorrect.
• The IP address setting of the
external device for the open
processing is incorrect.

Continue
• Mount only applicable power supply
modules. If the same error code is
displayed again, the possible cause is
a hardware failure of the power supply
module. Please consult your local
Mitsubishi representative.

■CPU module
Continue
• Replace the CPU module.
■SIL2 function module
• Replace the SIL2 function module.
■Safety function module
• Replace the safety function module.
Continue
• Replace the battery.
• Connect the battery connector to use
the file storage area in the device/label
memory or the latch function.
• Check the connection status of the
battery connector. If it is loose,
securely connect the connector.
Continue
• Unlock the write protect switch of the
memory card.
Continue
• Check if the time is correctly set in
parameter.
• Check if the specified SNTP server is
operating normally and there is no
failure on the network accessing the
SNTP server computer.
Continue
• Correct the default gateway IP
address.
• Set the same network address as that
of the IP address.
Continue
• Correct the port number.
Continue
• Correct the port number of the external
device.
Continue
• Correct the IP addresses.
• Check if the class of the IP address is
set to A/B/C.
