Methods and apparatus for object-based process control

摘要: The provides improved control devices, systems and methods for operation thereof. These rely on devices that provide virtual machine environments in which Java objects, or other such software constructs, are executed to implement (e.g., monitor and/or a device, process system). objects define blocks the basic functional unit of control. They also input, output body parts from formed, signals communicated between blocks. nested composite groupings used loops higher-level functions.
