  "term": "Fieldbus",
  "field": "Cybersecurity",
  "definition": "A digital, serial, multi-drop, two-way data bus or communication path or link between low-level industrial field equipment, such as sensors, transducers, actuators, local controllers, and even control room devices. Use of fieldbus technologies eliminates the need for point-to-point wiring between the controller and each device. A protocol is used to define messages over the fieldbus network, and each message identifies a particular sensor on the network.",
