Feldbusgeschwindigkeiten
Feldbusgeschwindigkeit, or fieldbus data rate, refers to the maximum rate at which a fieldbus network can transfer useful data between automation devices such as sensors, actuators, and controllers. This data rate, together with network topology and protocol features, directly affects control loop cycle times, diagnostics, and overall system responsiveness. Fieldbus speeds vary widely across standards, ranging from tens of kilobits per second in some process-oriented networks to hundreds of megabits per second in Ethernet-based implementations.
Different fieldbus families define their own speed regimes. Classic digital fieldbuses include Profibus and Foundation Fieldbus,
When selecting a fieldbus and its speed, engineers weigh requirements such as deterministic timing, distance, channel
