In this thesis, we propose a practical design and implement
method to build the distributed data link for a shop floor
control system. First, the CIM is reviewed and the distributed
data exchange mechanism is introduced. Owing to the complexity
of the software architecture, the gap between the design and
implementation stage is often quite large. The subject-based
addressing mode is proposed. Based on this method, the modules
among the system can exchange their data transparently and
network independently. Moreover, a development tool and the
component-oriented design method will be used in order to
develop the system modules rapidly. The key contribution of this
tool is to integrate general software components into a
customized module by using the subject name as the glue. As a
result, the complexity of the software development in the
distributed data exchange system is highly reduced.
