The data is arranged in the link variables memory as follows, with the data format limits
taken into account:
Figure 2-24
Note
Memory structure
The data in the link variables memory is always arranged randomly and may therefore
appear different (although the data format limits will still be taken into account).
Access via a link variable must be programmed as follows, in accordance with the memory
structure defined:
Program code
$A_DLB[0]
$A_DLB[1]
$A_DLW[2]
$A_DLD[4]
$A_DLD[8]
$A_DLD[12]
$A_DLR[16]
