3200T CPU Node Programming
Each 3200T CPU Node executes its own NetArrays project program. The program is created in NetArrays by
selecting
Add New Distributed Form (.dis)
from the Project menu.
This opens a new Distributed Main form named Dist1, which includes a Main object, a Scan object, a Stop Scan
object, and a Module object named Dist1_. (Subsequent distributed forms created from the Project menu will
be named Dist2, Dis3, etc.). You may change the name of Dist1or leave it as the default name.
Creating the rest of the project program is the same as creating any other project program in NetArrays, with
one exception. You can add Sequence, Module, Ladder, Fuzzy, or State form objects to the Main Form, and
then progress to defining the function performed in those forms. However, you must remember:
1
The naming convention for domain peer variables passed between 3200T Nodes within a domain is
DV_tagname_Dxx
. Where
DV_
signifies a domain peer variable,
tagname
is the alpha-numeric name
used for identification, and
_Dxx
signifies the domain node number where the variable is sourced from.
2
The naming convention for peer variables passed between domains is
GV_tagname_Nxx
. Where
GV_
signifies a global peer variable,
tagname
is the alpha-numeric name used for identification, and
_Nxx
signifies the node number where the variable is sourced from. The node number is defined as part of the
3200T/3201 Processor
Diagnostic Information
The Node Info object reports diagnostic information for the Node Processor configured in its Property Manager
display. Add the object to an MForm in the distributed logic created for the 3200T/3201 Processor card.
