Communicating to a Manufacturing Device using MMS/CORBA

摘要

The advantages of distributed systems are also applied to manufacturing systems due to their inherent distribution. However, the heterogeneity found in the current hardware and software and the underlying communication between the different components of the system make the development of these systems a difficult task. MMS allows a uniform communication with different hardware systems. On the other hand, CORBA makes the communication between several objects easier, reducing the implementation cost to a minimum. By joining both technologies a communication method between devices can be achieved. This method is location transparent and specific physical features independent. The MMS implementation over CORBA allows new devices to be added in a natural way, making use of the inheritance available in object oriented programming and the facility supplied by CORBA in the communication. In this work, this implementation has been used in order to communicate to a real device.
