PLC Programmer

The job profile

​PLC programmers often work in electrical engineering and IT companies and are responsible for the maintenance of machines and plants that use programmable logic controllers. Learn more about these professionals and their roles.

PLC programmers work with programmable logic controllers (abbreviated to PLC). These are small computers that have inputs and outputs, a built-in operating system and interfaces through which user programs can be loaded.

A PLC is connected to a machine and controllers its desired functions. These can be light barriers, temperature parameters, and other measuring devices.

PLC gets information through inputs (relays, sensors, etc.) and interacts with outputs (engines, valves, conveyor belts, etc.). E.g. if the temperature is above the desired level of 30 degrees, then switch an engine off.
