Event Code (Other Node Error) - Mitsubishi Electric MELSEC iQ-R Series User Manual

Event code (other node error)

There are three types of event codes: system, error, and operation.
The error codes can be checked with the [Event History] button in the [Error Information] tab in the "Module Diagnostics"
window of the RJ71DN91. ( Page 50 Error Information)

Event code Overview
00400 Master function I/O communication status change
00402 Auto configuration
00403 Parameter saving to flash ROM
00404 Master function error reset
00405 Slave function error reset
00406 Down node detection inhibit setting
00408 Own node reset execution
00C16 Network power abnormality
00C17 Network configuration abnormality
00C18 Parameter clearing in flash ROM
00C19 Bus off error occurrence
Errors
The event codes are issued for errors which occur on other nodes while the master function is used by the own node.
The node address (MAC ID) of the node where an error has occurred is stored in nn of the communication error code.
Communication error codes are stored in the following buffer memory area.

Cause
The I/O communication status of the master function has changed.
The auto configuration function has been executed.
Parameters have been saved in the flash ROM.
The master function error has been reset.
The slave function error has been reset.
The down node detection inhibit setting has been changed.
The CAN chip of the own node has been reset.
The power is not supplied to the network.
Other modules cannot be found on the network.
Parameters have been deleted from the flash ROM.
A bus off error has occurred.
Cause
After the communication started, network trouble has been detected.
This event occurs due to the following cause.
• The cable is not connected correctly.
The slave node did not respond.
[Example]
• The MAC ID and communication speed do not match.
• The slave node went down.
• The terminating resistor came off.
The slave node has responded to an unspecified error.
The error cause can be acquired by the communication error information read.
The slave node has responded to the error at connection establishment.
The error cause can be acquired by the communication error information read.
The input data size of the parameter in the slave node set with the parameter and the
input data size of the actual slave node are different.
The output data size of the parameter in the slave node set with the parameter and the
output data size of the actual slave node are different.
The response data of a function which is not supported by the RJ71DN91 has been
received.
The connection is already in the specified mode.
An incorrect data has been transmitted from the slave node at connection establishment.
[Example]
• The terminating resistor came off.
The connection with the slave node which has been already connected was going to be
established.
[Example]
• The connection with the slave node has been disconnected because an error has
occurred.
• Stable communications cannot be performed because the circuit load is high.
