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.
n = D 300×(0xFD - Unit Address)
The following table describes the unit address for each option port.
