1.16 IP Address Change Function
Usage methods
Write operation
■Case of the CPU module (built-in Ethernet port part)
Follow the steps below.
1. Store the value to be changed in 'IP address setting' (SD1518 to SD1525).
2. Turn off and on 'IP address storage area write request' (SM1520).
3. Check the write results with the following special relays and special registers.
4. Power off and on or set the CPU module.
5. If the IP address stored in the IP address storage area (system memory) is a valid value, the stored IP address is set as
the IP address of the CPU module (built-in Ethernet port part). (If the value is invalid or not set, the value set in the
module parameters is set as the IP address of the CPU module (built-in Ethernet port part).)
6. Check the IP address with the buffer memory. ( Page 345 CPU module (built-in Ethernet port part))
■Case of the RJ71EN71 or RnENCPU (network part)
Follow the steps below.
1. Store the values to be changed in 'IP address setting' (Un\G11700 to Un\G11705) and 'Communications by Network No./
Station No.' (Un\G11706 to Un\G11708).
2. Turn off and on 'IP address storage area write request' (Un\G11709.0).
3. Check the write results with the following buffer memory areas.
4. Power off and on or set the CPU module.
5. If the IP address stored in the IP address storage area (flash ROM) is a valid value, the stored IP address is set as the IP
address of the RJ71EN71 or the RnENCPU (network part). (If the value is invalid or not set, the value set in the module
parameters is set as the IP address of the RJ71EN71 or the RnENCPU (network part).)
6. Check the IP address with the buffer memory. ( Page 336 RJ71EN71, RnENCPU (network part))
