A method for automating a process plant includes configuring field components of the process plant as a swarm of self-organizing agents where each agent communicates with adjacently physically connected agents. The method includes reacting on requests generated by requesting agents by responsible agents assigned based on a prioritization mechanism established using a topological representation of the process plant. The prioritization mechanism is established by assigning a penalty value to each request and forwarding the request via one or more paths using the topological representation by incrementing the penalty value at an agent that forwards or reacts on the request depending on the type of request and / or agent.
