Fieldbus communication refers to the digital exchange of data between automation components such as sensors, actuators, process controllers, and control systems. It replaces traditional point-to-point cabling with a unified bus system, thereby enabling significantly more efficient, stable, and scalable networking. At Demig, fieldbus communication forms the backbone for the integration of process control systems such as Prosys into complex plant environments.
Operating Principle and Advantages of Fieldbus Communication
Fieldbus systems transmit control and measurement data digitally and in real time via a shared data line. In this process, multiple devices—such as temperature sensors, valves, and control units—are grouped together in a network. Demig supports common standards such as Modbus, Profibus, CANopen, and EtherCAT, thereby enabling cross-vendor integration.
Advantages of fieldbus communication:
- Reduced wiring effort
- Greater data security and diagnostic capabilities
- Real-time transmission of measurement and control data
These advantages are particularly crucial for complex, zone-controlled systems such as continuous or chamber furnaces.
Integration with Demig process controllers and prosys/2
Demig’s process controllers (e.g., DE-CP 3XX and DE-CP 5XX) are fieldbus-compatible and can be seamlessly integrated into digital control architectures. In combination with the prosys/2 process control system, this creates a consistent communication structure that enables the following:
- Addressing and remote parameterization of individual controllers via the control system
- Automatic data synchronization between the control system, visualization, and documentation
- Easy integration of additional components or subsystems
Fieldbus communication is a key factor, particularly in retrofit projects, for cost-effectively digitizing existing plants.
Practical benefits in heat treatment
In industrial heat treatment, fieldbus communication ensures stable, transparent, and flexibly expandable processes. Users benefit from:
- Faster commissioning and easier maintenance
- Scalable system architectures for future requirements
- Standard-compliant communication with higher-level IT systems (MES/ERP)
Demig ensures that all systems—from individual sensors to control technology—communicate seamlessly with one another and work together on a common digital platform.
Conclusion
Fieldbus communication is a key technology for modern, digitized plant control. It connects process controllers, sensors, and the prosys/2 process control system into an intelligent, high-performance integrated system. Demig relies on proven industry standards and offers maximum flexibility for new installations and retrofit projects—future-proof, efficient, and ready for integration.
