Hierarchical Control Modelling Architecture for Modular Distributed Automation Systems

Modern design approaches for manufacturing system organize the control architecture in the same way as the functional structure of the plant. This leads to a modular approach that is based on composition of automation components. This paper introduces a hierarchical architecture that is based on a generic internal structure of automation components. This includes logic, diagnostics as well as human machine interface (HMI). The HMI architecture is again organized in the same way as the functional structure of the plant. This results in a clear modelling process enabling reduced engineering effort and simple maintenance. It can also serve as a basic architecture for reconfiguration approaches.
