Kenttäväyläkommunikaatio

Kenttäväyläkommunikaatio, also known as fieldbus communication, refers to a robust and industrialized network technology used for the communication between automated devices and control systems in industrial settings. Unlike traditional point-to-point wiring where each sensor or actuator would have a dedicated cable running back to the control room, fieldbus systems utilize a single serial cable to connect multiple devices. This shared communication link significantly reduces wiring complexity, installation costs, and maintenance efforts.

The core principle of fieldbus is to move intelligence and communication capabilities closer to the "field" where the sensors and actuators are located. This distributed intelligence allows for more efficient data exchange and processing. Fieldbus protocols define the rules for data transmission, ensuring standardized communication between devices from different manufacturers. Common fieldbus protocols include PROFIBUS, DeviceNet, FOUNDATION Fieldbus, and Modbus. Each protocol has its own characteristics regarding speed, determinism, and suitability for specific applications.

The benefits of implementing kenttäväyläkommunikaatio are numerous. Beyond the reduction in cabling, it allows for more sophisticated diagnostics, remote configuration, and easier integration of new devices. This leads to improved system reliability, increased flexibility in plant design and modification, and ultimately, higher productivity. Fieldbus systems are essential components in modern automation architectures across various industries such as manufacturing, process control, and building automation.
