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 is applied to two benchmark production systems at Martin Luther University in Germany. (More)
