List of Error Codes
Error classification by error number
Error codes are classified by error number as follows.
Error codes related to the safety remote I/O module
Errors of the safety remote I/O module are classified into the following four types.
List of Error Codes
Error code Classification Reference
0000H to 3FFFH Safety remote I/O module error Page 118 Error codes related to the safety remote I/O module
D000H to DFFFH CC-Link IE TSN error Page 124 Error codes related to CC-Link IE TSN
8400H to 84FFH CC-Link IE TSN safety communications error Page 126 Error codes related to CC-Link IE TSN safety
communications
Error status Description
Major error Error because of which the module stops, such as hardware failure. The safety functions (safety I/O, safety diagnostics, and safety
communications) stop.
Moderate error Error because of which the module stops, such as a parameter error related to module operation. The safety functions (safety I/O, safety
diagnostics, and safety communications) stop.
Minor error Error after which the module continues its operation, such as double input discrepancy detection. The safety functions keep operating.
Communication
error A CC-Link IE TSN safety communications error that causes the module to continue operating. The safety functions (safety I/O, safety
diagnostics, and safety communications) stop.
Error code
(hexadecimal) Classification Error name Description and cause Action
0001H Major error Hardware failure A hardware error was detected. • Review the connected devices, wiring, and voltage.
• When the connected devices, wiring, and voltage
have no errors, there may be an influence from noise
or a hardware failure. Take measures to reduce noise.
• If the same error occurs again even after measures
have been taken against noise, the module may be in
failure. Please consult your local Mitsubishi
representative.
0101H Moderate error Self-diagnostic error An error was detected by the self-
diagnostics.
0102H
*1
Moderate error External power supply
voltage error An external power supply error
was detected. • Review the connected devices, wiring, and voltage.
• Power on the external power supply at the same
timing of power-on of the module power supply.
• There may be an influence from noise of external
wiring (such as power supply part and I/O signal part).
Review the connected devices and wiring.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi
representative.
0103H Moderate error Non-volatile memory
data error (IP address
information) The IP address and subnet mask
stored in the non-volatile memory
are abnormal. • The module will be automatically recovered
immediately after the error occurs. However, the
stored IP address and subnet mask are lost, and
operation is performed assuming that the following
are stored.
IP address: 192.168.3.250
Subnet mask: 255.255.255.0
• Take measures against noise with a shielded cable for
connection.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi
representative.
0104H Moderate error Restart not performed
after safety module
validation The module has not been
restarted after the safety module
validation. • Restart the safety remote I/O module. After
performing safety module validation, safety
communications can be performed by restarting the
module.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi
representative.
