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]
