Advantages for users
 Transparent Access to relevant information
l
like Variables, Datatypes, Function Blocks, Structures, Tasks, etc.
 Less Engineering time in overall control systems
(Controller, HMI, SCADA, ERP, etc.)
 Transparent Communication independent from system
and network
“Communication will never be the same”
