At a Glance: PLC Programming
A Programmable Logic Controller (PLC) is a computer control system used in industrial applications to help automate processes on the factory floor. Any computer that takes signals from input devices like thermistors, pressure transducers, and other sensors, and uses them to control the state of output devices like switches, relays, lights, and heaters, is a PLC. If you’re looking to integrate thermal, electrical, or mechanical control schemes into your production processes, you’ll need the help of a PLC programmer to code the logic behind your controllers.
PLC programmers help write the code that will allow you to bring automation to processes in a wide variety of business areas, including the food, metallurgy, and automotive industries. They can use languages like Ladder Logic, Instruction List (IL), Structured Test (ST), Function Block Diagram (FBD), or Sequential Function Charts (SFC) to help you bridge the gap between digital and analog machinery. PLC programmers on Upwork can help you design and deploy expert systems, advanced process control systems, regulatory controls, and vision systems, then integrate them into your manufacturing floor.
