Industrial Automation at TEWE-Biogas
Control for complex continuous processes – with integrated SCADA layer
Biogas plants place particular demands on automation: continuous operation, biological processes and high availability.
TEWE-Biogas develops automation solutions based on in-house PLC and SCADA software that make this complexity manageable.
TEWE Control Architecture
A Unified, Evolving Control System

From grown isolated solutions to a coherent control system
In many existing industrial and energy plants, control systems have evolved over time: different PLC generations, multiple manufacturers, proprietary modules and hardly compatible interfaces. Processes operate in parallel rather than as an integrated whole – extensions become complex, service effort increases and transparency is lost.
The addresses this challenge directly.
In-house development as the foundation
At the core of the Control Architecture is the consistent in-house development of control software. TEWE and TEWE-Biogas develop PLC logic, process sequences, SCADA systems, visualization and overall system architecture themselves – tailored to real operating conditions rather than rigid standard solutions.
The result is not a black box, but an open, transparent control and supervisory architecture that clearly represents processes, enables centralized monitoring and remains expandable over the long term.
Retrofit with a system approach – not piecemeal solutions
A key focus of the Control Architecture is the retrofit of existing plants. Instead of replacing individual control modules in isolation, existing systems are restructured at an architectural level: different control layers, sensors, actuators, peripherals as well as existing visualization and supervisory systems are consolidated into a unified PLC and SCADA architecture. This transforms a wide range of incompatible components into a cohesive, consistently operating system – stable, maintainable and future-proof.
Evolving instead of closed
The TEWE Control Architecture is deliberately not a closed system but designed as an evolving system. New processes, extensions or additional plant components can be integrated without destabilizing existing logic.
The SCADA layer is also modular in design and grows with operational requirements – both technically and economically.
Combined expertise from three domains
The strength of the Control Architecture lies in the integration of know-how from:
- industrial automation and material flow / feeding technology
- complex biological and technical continuous processes
- precise measurement and weighing technology from TELL
This expertise is embedded directly into PLC and SCADA programming – not as theory, but as proven, practice-oriented process logic.
Your benefits
- In-house software and SCADA development instead of standard integration
- End-to-end PLC and supervisory system architecture from a single source
- Retrofit expertise for heterogeneous legacy plants
- Open, expandable and maintainable over the long term
TEWE Control Architecture – when grown technology becomes a coherent system that continues to evolve.
In-house programming for maximum process control
WE-Biogas programs all levels in-house – including the SCADA architecture.
Process data from substrate management, fermenters and peripheral systems are centrally collected, visualized and evaluated.
SCADA provides transparency, alarm management and historical analysis – both locally and remotely.
Automation for 24/7 operation
Robust PLC structures and clearly designed SCADA systems ensure:
- stable continuous operation
- centralized process monitoring
- fast response to deviations
Retrofit of existing biogas plants
A key focus lies on the retrofit of grown, existing plants.
Different control and supervisory systems are consolidated into a unified PLC and SCADA structure – without unnecessarily affecting ongoing operation.
