This paper proposes an advanced industrial controller prepared for hazardous industrial environments, namely natural gas odorisation. Its design and conception is focused on robustness and reliability, with high flexibility to allow local and remote monitoring and control. Instead of a centralized approach, where the computational load relies on a unique processor, we propose a distributed architecture, where the various control tasks are distributed among the existing microprocessors, like in a DCS system, but yet exhibiting a fast response time between inputs and outputs, like a PLC.
