7-1 Overview
CPU Unit can control MC Unit with the following three different methods of
data I/O.
1,2,3... 1. Data exchange with allocated PC area words.
2. Data exchange with allocated DM area words.
3. Data exchange with allocated Custom area words
.
7-1-1 Data Exchange Area Overview
The following table shows the allocated PC interface area to be refreshed
cyclically.
The number of motion tasks automatically sets the actual number of trans-
ferred words. In addition, [the area range setting] in the allocated DM area and
[the physical axis setting] in axis allocation parameters determine the number
of Custom area words.
