14.3.2.2 Addressing range of the target system
Address range of a memory type is the addressing range for this type of memory that spans the lowest and
highest possible address numbers. The lowest and highest possible address number depends on the particular
memory type.
If you execute operations, which communicate with the target system, then the Programming Tool PLC828
recognizes your CPU version. When generating your program, you must ensure that you only use the address
range valid for this CPU. If you attempt to load a program that accesses addresses ranges, which are not valid for
this CPU, then an error message is output.
