Field I/O
Field I/O are devices that communicate with a controller or data aggregator to either send input data or receive output data. Input data may include readings about a given environment/device state from sensors, while output data may include data sent back to actuators for them to either undertake actions or change parameter values.[1] These devices are frequently embedded devices running on lightweight embedded operating systems or RTOSes.

| Smart Sensors | General |
A device that procures a voltage or current output that is representative of some physical property being measured (e.g., speed, temperature, flow). [1] Smart sensors take this functionality and add on on-device processing and network communication. |
| Variable Frequency Drive (VFD) | General |
A type of drive that controls the speed, but not the precise position, of a non-servo, AC motor by varying the frequency of the electricity going to that motor. VFDs are typically used for applications where speed and power are important, but precise positioning is not. [1] VFDs can be network connected. |
