6.6
The developer can define different MOBY data structures depending on the structure of the
application. Some example structures are given below.
1st example
Four SLGs are parameterized. One command is assigned to each write/read device. MOBY
parameters (DB 45), MDS commands (DB 47), and data (DB 48) are assigned to different
data blocks. The declaration view is shown.
Block: DB45; MOBY parameters
Address

+0.0
*300.0
=1200.0
Block: DB47; 4 MDS commands

+0.0
*10.0
=40.0
Block: DB48; MOBY data

=1024.0
When the data blocks have been defined, the "actual value" of the data must be edited using
the "View → Data view" menu.
