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 alway
s 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).

Note
The ax
is actual values and distances-to-go can be separately requested:
•
DB2600.DBX0001.1 Request axis actual values
•
DB2600.DBX0001.2 Request axis distances-to-go
If the particular request is set, then the NCK supplies these values for all axes.
