Manufacturing Information Bus from the Perspective of Cyber Physical Manufacturing System (CPMS)

Smart Factory of Industry 4.0 is a complex system containing various aspects and capabilitis of the factory of the future based on Internet of Things (IoT), Internet of Men (IoM), and Internet of Service (IoS). There have been numerous concepts and scenarios how it looks like, how it should be, and commercial vendors advocate their products can provide solutions to some parts of the Smart Factory. This often confuses stakeholders who want to adopt Smart Factory. To show and guide the multi-aspects and technology for Smart Factory in a comprehensive fashion, our research team developed a conceptual framework, called Cyber Physical Manufacturing System (CPMSPS). In this paper, we focus on the manufacturing information bus from the perspective of CPMS. Specifically, we developed a reference architecture for the manufacturing information bus for the Smart Factory that can be used for information acquisition, analysis, and application for the various stakeholders at the levels of Machine, Factory, and Enterprise Resource Planning. Also in this paper, an implementation process of the reference architecture is presented and demonstrated via case study.
