■Operation of the special relays and special registers, or of the buffer memory
The following section shows the operation of the special relays and special registers or of the buffer memory when writing to
the IP address storage area.
• Operation at normal completion
• Operation at abnormal completion
■Cause of error at abnormal completion
• If the data is not written correctly into the IP address storage area (system memory) in the CPU module (built-in Ethernet
port part), the cause of the error is stored in 'IP address storage area writing error cause' (SD1526).
• If the data is not written correctly into the IP address storage area (flash ROM) in the RJ71EN71 or the RnENCPU (network
part), the cause of the error is stored in 'IP address storage area writing error cause' (Un\G11711).
Stored value Cause of error
100H The value for 'IP address setting' (SD1518 to SD1525) exceeds the setting
range.
200H An error occurred during write.
300H Writing cannot be performed since the following functions are being executed.
• CPU module data backup/restoration function
400H Writing was started during the clear processing.
Stored value Cause of error
100H The value for 'IP address' (Un\G11700 to Un\G11701) exceeds the setting
range.
101H The value for 'Default gateway' (Un\G11704 to Un\G11705) exceeds the
setting range.
102H The network address of 'Default gateway' (Un\G11704 to Un\G11705) or of the
gateway IP address is different from that of the IP address of the own node.
103H The value for 'Network number' (Un\G11706) exceeds the setting range.
104H The value for 'Station number' (Un\G11707) exceeds the setting range.
105H The value for 'Transient transmission group number' (Un\G11708) exceeds
the setting range.
106H The port 1 and port 2 IP addresses written in the IP address storage area are
the same.
107H The port 1 and port 2 network numbers or station numbers written in the IP
address storage area are the same.
200H An error occurred during write.
400H Writing was started during the clear processing.
