Note
The programming engineer (NCK and PLC) is responsible for organizing (structuring) this
memory area. Every
storage position in the memory can be addressed provided that the limit
is selected according to the appropriate data format (i.e. a 'DWORD' for a 4byte limit, a WORD
for a 2byte limit, etc.). The memory area is always accessed with the information about the
data type and the position offset within the memory area. The PLC variables can be read or
written in the NC program $A_DBB[n] ("n" stands for the position offset in bytes).
