Abstract
The cyber-physical system is the core concept of Industry 4.0 for building smart factories. We can rely on the ISA-95 architecture or the 5C architecture to build the cyber-physical system for smart factories. However, both architectures emphasize more on vertical integration and less on horizontal integration. This article proposes the 8C architecture by adding 3C facets into the 5C architecture. The 3C facets are coalition, customer, and content. The proposed 8C architecture is a helpful guideline to build the cyber-physical system for smart factories. We show an example of designing and developing, on the basis of the proposed 8C architecture, a smart factory cyber-physical system, including an Industrial Internet of Things gateway and a smart factory data center running in the cloud environment.
Highlights
The cyber-physical system (CPS) is the core concept of Industry 4.0 advocated by the German government for building smart factories to bring about the fourth industrial revolution
We show an example of developing a smart factory CPS (SF-CPS), including an Industrial Internet of Things (IIoT)[11,12] gateway and a smart factory data center, running in the cloud,[13] on the basis of the proposed 8C architecture
The ‘‘Infrastructure as a Service (IaaS)’’ and ‘‘Platform as a Service (PaaS)’’ modes are adopted to deploy and launch three virtual machines (VMs) atop the private cloud, one for running the SF-CPS data center main program, another for running a Not only Structured Query Language (NoSQL) MongoDB database, and the other for running the programs related to the levels/facets of conversion, cyber, cognition, configuration, coalition, customer, and content
Summary
The cyber-physical system (CPS) is the core concept of Industry 4.0 advocated by the German government for building smart factories to bring about the fourth industrial revolution. The configuration level gives feedback back to the physical system according to the decisions made Both the ISA-95 and the 5C architectures emphasize more on vertical integration and less on horizontal integration. We show an example of developing a smart factory CPS (SF-CPS), including an Industrial Internet of Things (IIoT)[11,12] gateway and a smart factory data center, running in the cloud,[13] on the basis of the proposed 8C architecture. In this example, we can see how sensor and actuators are connected to machines and how sensed data are converted into information.
