Abstract: The paper deals with the functional safety of distributed control systems following the component-based approach. A control component is classically defined as a software unit allowing the control of a physical process. When a fault occurs in the plant, the system should be reconfigured dynamically to be adapted by adding-removing or updating software components for the safety of the controlled physical processes. An agent-based architecture is proposed therefore to control the plant’s evolution before applying any possible reconfiguration scenario of the system. When the system is distributed on networked controllers, we propose a control agent for each device but we need also a coordination agent to allow safety distributed reconfigurations. The unique coordinator uses well-defined matrices and a protocol for this coordination. We model the whole architecture by using ordinary Petri nets and apply SESA for the verification of CTL properties of the system. The paper’s contribution i s applied to two benchmark production systems at Martin Luther University in Germany. (More)
