24003 Auto configuration request
24004 Parameter save request to Flash ROM

Cause
The polling response data length differs from the data length read from the slave node at
connection establishment.
For divide receive of the polling response, the first divided data has been received twice.
[Example]
• The terminating resistor came off.
For divide receive of the polling response, the number of the received divided data is
different from the expected one.
[Example]
• The terminating resistor came off.
For divide receive of the polling response, the intermediate data or final data has been
received before the first divided data has been received.
[Example]
• The terminating resistor came off.
Two or more same node addresses (MAC ID) are detected among the parameters.
An improper connection type has been specified by the slave node at connection
establishment.
The error cause can be acquired by the communication error information read.
The transmit byte of the slave function is out of range.
The polling connection of the slave function became timeout.
[Example]
• The terminating resistor came off.
• The master node is abnormal.
The connection other than the explicit message or polling.
[Example]
• The connection type of the master node is set to other than the polling.
The number of receive byte of the polling exceeds the maximum number of receive
points.
[Example]
• The number of I/O points setting of the master node exceeds the maximum number of
the RJ71DN91.
An error has occurred in a polling fragmented sequence.
Although the data consistency setting of the master function is enabled, DNTMRD or
M+RJ71DN91_MasterRead is not executed in three sequence scans.
Although the data consistency setting of the master function is enabled, DNTMWR or
M+RJ71DN91_MasterWrite is not executed in three sequence scans.
Although the data consistency setting of the slave function is enabled, DNTSRD or
M+RJ71DN91_SlaveRead is not executed in three sequence scans.
Although the data consistency setting of the slave function is enabled, DNTSWR or
M+RJ71DN91_SlaveWrite is not executed in three sequence scans successively.
Cause
I/O communication start has been instructed by I/O communication request.
I/O communication stop has been instructed by I/O communication request.
Master function error reset request has been.
Auto configuration request has been transmitted.
Parameter saving to flash ROM has been requested.
Slave function error reset request has been transmitted.
A reset request of the own node has been received from other nodes.
A reset has been requested to other nodes.
Parameter clearing in flash ROM has been requested.
