Feldbusnetze

Feldbusnetze, often translated as fieldbus networks, are industrial digital communication systems designed for real-time control and data acquisition in automation environments. They replace traditional point-to-point wiring between sensors, actuators, and control systems, offering a more efficient and flexible method for connecting field devices. These networks typically operate on a serial bus architecture, allowing multiple devices to share a single communication line.

The primary advantage of feldbusnetze lies in their ability to reduce cabling costs and complexity. Instead of individual wires for each signal, a single bus cable connects all devices. This simplification also leads to faster installation and easier maintenance. Furthermore, feldbusnetze enable bidirectional communication, allowing for more advanced diagnostics, parameterization of devices, and the transmission of more complex data beyond simple on/off signals.

Various fieldbus protocols exist, each with its own characteristics and applications. Common examples include PROFIBUS, Modbus, DeviceNet, and CANopen. The choice of protocol depends on factors such as required data transfer rates, noise immunity, determinism (guaranteed response times), and the specific needs of the automation task. These networks are crucial components in modern industrial automation, factory automation, and process control systems.
