This paper details the needs, demands and specifications to be incorporated and satisfied to design safety bus systems for modern industries. Distributed control systems in industries are connected via bus systems, and need efficient and uninterrupted communication between all bus stations. Therefore, it is compulsory that these communications are fault tolerant and safe. For safety related systems, further safety layers are mandatory to perform these requirements. In a safety related application it is important that the safe protocol alone is not able to achieve this task without a safety source node at one end and a safe destination node at the other. Only the combination between safety related protocol and safety related hardware nodes can accomplish the requirements for safety related networks systems.

This paper presents an advanced control structure exploiting a GPC master-slave solution to regulate the oxygen and nitrification process of a simulated water treatment plant. The slave controller regulates the process variable, whilst the master controller changes the set-point for the slave controller depending on the output behaviour of the system. The presented structure outperforms significantly the standard control structure. Different weather conditions are simulated and analysed for comparison
