This operation can be performed by storing the IP address to be changed in SD1292 to SD1297 and turning off and on
SM1292 (IP address storage area write request).
(1) Operating procedure
The following shows the write operation flow.
Store the value to be changed in
SD1292 to SD1297
• IP address
• Subnet mask pattern
• Default router IP address

Execute writing to the IP address storage
area (flash ROM).
Confirm the write completion.
• Write complete (SM1293) is turned on.
• Write error (SM1294) is turned off.

(Example) When storing the IP address (192.168.3.40 (C0A80328H)) to
SD1292 and SD1293
1) Convert the IP address to be changed from decimal (192.168.3.40) to
hexadecimal (C0A80328H).
2) Store the IP address converted to hexadecimal in the SD.
