Memory Allocations Section 9-9
9-9-2 DM Area Allocation
The memory allocation about system setup is shown as the following diagram.
These data will be allocated to the DM area of PLC. The beginning DM chan-
nel n is calculated by the following equation.
Note 1. DM area from n to n+154 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. DM area n+155 and n+156 will display the IP address used by the CP1W-
CIF41 when the power is turned ON.
3. When the IP address is illegal, such as using CLASS D, CLASS E IP
address, the values in words n+3 and n+155 will be different, 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 C and Appendix D for details.
n = D 300×(0xFD - Unit Address)
The following table describes the unit address for each option port.
