Data structure: Command channel for the measuring cycle
The measuring DB includes 16
data words (DW n to DW n+7). The initial address of a channel can be determined by means
of the following equation:
n = (k 8) - 7, where k = Magazine No. = 1...16

This measuring DB forms the interface to the measuring cycle in the NC.
