17-4 Memory Allocations
The memory allocation about system setup is shown as the following diagram. These data will be allo-
cated to the DM area of PLC. The range of the DM area is D1300 to D1456.
Note 1 D1300 to D1454 can only display all of the settings stared in the unit. Modification in this area is invalid to
the CP1W-CIF41 Ethernet Option Board.
2 D1455 and D1456 will display the IP address used by the CP1W-CIF41 when the power is turned ON.

When the IP address is illegal, such as using CLASS D, CLASS E IP address, the values in D1303 and
D1304 will be different from the ones in D1455 and D1456, and the CP1W-CIF41 will temporarily use the
default IP address (192.168.250.1). Use this IP address to modify the IP address settings through Web
browser.
4 When the system settings are wrong, A525 can be used to reset CP1W-CIF41.
Refer to Appendix A-2 for details.
