List of Error Codes and the Warning Codes
This section describes error codes and warning codes.
If an error not described in this manual occurs on an IO-Link device, refer to the manual of the IO-Link device
used.
List of Error Codes and the Warning Codes
The error codes and warning codes are classified into the following three types.
Classification Description
Error code Major error An error that cannot be recovered
Moderate error An error where the module cannot continue to operate
Warning code Minor error An error where the module can continue to operate
Error code
(hexadecimal) Classification Error definition and cause Action
0001H Major error The WDT (watchdog timer) has timed out. • Take measures against noise with a shielded cable
for connection. Then turn off and on the module.
• If this error persists, the module may be in failure.
Please consult your local Mitsubishi representative.
0002H Major error The bus inside the module is faulty.
0003H Major error The data in the nonvolatile memory are faulty.
0004H Major error An error has been detected in the RAM diagnostics
upon start up.
0005H Major error Communication inside the module is faulty.
0101H Moderate error The module/sensor power supply voltage or the output
power supply voltage is faulty. Check US voltage drop flag (18V or lower) (RX28), UA
voltage drop flag (18V or lower) (RX29), and UA voltage
drop flag (11V or lower) (RX2A), and confirm the wiring
and status of the relevant power supplies.
0102H Moderate error Short-circuit has been detected on a port or pin. Check Channel n (CQ/Q) short-circuit detection flag
(RX10 to RX1F) and Channel n (L+) short-circuit
detection flag (RX20 to RX27), and confirm the status of
the relevant channel or pin.
0103H Minor error The station number/network setting have been changed
with the module power on. Set the switch again to the station number or network
number that has been set before.
0104H Minor error The setting was changed while the system was in
operation. This error is automatically recovered. However, if this
error persists, the module may be in failure. Please
consult your local Mitsubishi representative.
D529H Major error A hardware error has occurred in the communication
LSI. • A malfunction may have occurred due to noise or
others. Check the cable distance or grounding
condition of each device. Then take measures
against noise.
• If this error persists, the module may be in failure.
Please consult your local Mitsubishi representative.
D52AH Major error
D52BH Major error
D52CH Major error
D0A0H Moderate error A response wait timeout has occurred in transient
transmission. • If an error has been detected on the own station,
target station, or relay station, check and address the
error.
• Decrease the usage frequency of transient
transmission, and retry the operation.
• If the master station (submaster station) is in the
mode "Online (high-speed mode)", switch the mode
to "Online (normal mode)", and retry the operation.
• Check cables of the request source and switching
hub connection for any error.
D0A1H Moderate error A transmission completion wait timeout has occurred in
transient transmission.
D0A2H Moderate error A transmission wait timeout has occurred in transient
transmission. • Decrease the usage frequency of transient
transmission, and retry the operation.
• Check cables of the request source and switching
hub connection for any error.
