One plant - one process control system, that is the norm in industry. With us it is different! In our laboratory, we have a process engineering plant that represents a sewage treatment plant process. Sensors and actuators on an industrial scale are installed in this plant. The process flow can be initiated via six different process control systems. Planning, controlling, regulating and simulating the running process on the plant is the main focus of the practical course for the students of the Master Automation Technology.
The control systems of the following manufacturers are used by us:

Honeycomb PlantCopyright: © Martin Braun
This modular process plant consists of four subplants. Each plant section has a hexagonal footprint, which is why the overall plant at the IAT is also referred to as a "honeycomb". The subplants each consist of a container with various sensors and actuators. Each sub-plant is controlled by a decentralized control system from different manufacturers, which also allows us to achieve modularization in terms of process control of the overall plant. The result is that, depending on current requirements, the respective plant section can be flexibly modified or even removed from the plant complex.
The orchestration (Process Orchestration Layer; POL), i.e. the retrieval of the individual services of the various decentralized control units of the plant sections, is handled by a process control system (PCS). In the DCS, the process of each subsystem is also reassembled into an overall process. This manufacturer-independent standard for describing plant sections is defined by the NAMUR Module Type Package (MTP) in accordance with VDI/VDENAMUR 2658.
