Terms

Term | Definitions
automated systems | systems that use computerized, electronic, and/or advanced mechanics to control a system with little or no human involvement required
encoders | rotary encoder: a sensing devices used to count, read, or take measurements of moving devices as to inform the controller of its current position and/or speed. Encoder as a general term: any devic ...
field devices | functional devices external to the PLC or controller
input | the data entering a system from sensors, buttons, and other devices. Terminal/s used as at input connection.
ladder logic | a logic system used for programming modern PLCs having a layout similar to industrial logic drawings. They resemble the rungs of a ladder.
output | the data exiting a system to control indicators, motors, valves, relays, and other devices. Terminal/s used at an output connection.
program | set of computer instructions to perform a specific set of tasks based on that state/s of input/s and outputs
Programmable Logic Controller (PLC) | a durable device for industrial process control using ladder logic programming. Wind turbines use PLCs for special control purposes.
sensors | devices that read, record, or otherwise are capable of taking specific types of measurements for use with controllers
