List Of Error Codes; Error Code For Module Diagnostics (Own Node Error) - Mitsubishi Electric MELSEC iQ-R Series User Manual

4.6

List of Error Codes

The error codes for troubleshooting are divided into the following three types.
• Error code for module diagnostics: This type of error code is displayed in the "Module Diagnostics" window. These codes
are issued for errors which occur on the own node (while the master function or slave function is used). ( Page 59 Error
code for module diagnostics (own node error))
• Event code: This type of error code is displayed in the "Event History" window. These codes are issued for errors which
occur on other nodes while the master function is used by the own node. ( Page 62 Event code (other node error))
• Communication error code: This type of error code is stored in the buffer memory. ( Page 59 Error code for module
diagnostics (own node error),  Page 62 Event code (other node error))
In addition, there are the following four types of error code for each application.
• Error code for hardware test ( Page 52 Checking the status and result of hardware test)
• Error code for communication test ( Page 53 Checking the status and result of communication test)
• Execution error code for message communication ( Page 79 Message communication result (Un\G288 to Un\G303))
• General DeviceNet error code ( DeviceNet Master-Slave Module User's Manual)

Error code for module diagnostics (own node error)

The error codes for module diagnostics are issued for errors which occur on the own node (while the master function or slave
function is used).
The error codes can be checked in the [Error Information] tab in the "Module Diagnostics" window of the RJ71DN91. (
Page 50 Error Information)
Communication error codes are stored in the following buffer memory area.

1080H The number of writes to the flash ROM
has exceeded 100000.
18F0H F0FFH The setting of the node address setting
switch or the mode setting switch is
changed during operation.

2221H The setting value is out of the range.
3002H 02FEH Both the number of input points and the
number of output points of the slave
node set by the parameter are 0.
3003H 03FEH The node address of the slave node
set by the parameter is out of range.
3004H 04FEH The message group of the slave node
set by the parameter is out of range.
3005H 05FEH The connection type of the slave node
set by the parameter is out of range.
Action
Replace the module.
Restore the setting of the node address setting switch and
the mode setting switch.
• Check the parameter setting.
• Match the module set by the project of the engineering
tool to the version of the mounted module.
• If the error occurs again even after taking the above, the
possible cause is the data memory in the CPU module,
the memory card, or a hardware failure of the intelligent
function module. Please consult your local Mitsubishi
representative.
Set the number of input and output points according to
specifications for slave node in "Slave Node Information"
of "Master Function Parameters" under "Basic Setting".
Set "Node Address" to 0 to 63 in "Slave Node Information"
of "Master Function Parameters" under "Basic Setting".
Set "Message Group" properly in "Slave Node
Information" of "Master Function Parameters" under
"Basic Setting".
Set "Connection Type" properly in "Slave Node
Information" of "Master Function Parameters" under
"Basic Setting".
