The gray area above represents the byte memory locations being overlapped
when word address is used consecutively (DB1.DBW0, DB1.DBW1, DB1.DBW2,
etc).
If DB1.DBW0 is used as the first address in the Siemens processor, the next
word address that can be used without overwriting the data would be
DB1.DBW2.
Double Word Address in Data Block:
DB1.DBD1
2#0000_0110 2#0000_0000 2#0110_0001 2#0011_0110 2#1100_0110
DB1.DBD0
The gray area above represents the byte memory locations being overlapped
when double word address is used consecutively (DB1.DBD0, DB1.DBD1,
DB1.DBD2, etc).
If DB1.DBD0 is used as the first address in the Siemens processor, the next
double word address that can be used without overwriting the data would be
DB1.DBD4.
All of the above share the same memory locations in the processor.
Note: Incorrect memory location addressing can cause the data to be overwritten.
