A PLC (Programmable Logic Controller) is a specialized computer used to automate industrial processes. It controls machines, sensors, and equipment in systems such as production lines or industrial facilities.

What is a PLC used for?

PLCs are used to monitor and control processes like pumps, motors, valves, and manufacturing equipment. They enable reliable and automated operation in industrial environments.

A PLC receives input data from sensors, processes it according to programmed logic, and sends commands to machines or actuators. This allows it to coordinate and control physical processes in real time.

Why is PLC security important?

PLCs often control critical infrastructure and industrial operations. If compromised by cyberattacks, they can cause production disruption, equipment damage, or even physical safety risks.

How is a PLC different from a traditional IT system?

A PLC is designed to control physical processes in real time, while traditional IT systems mainly manage data and applications. PLCs therefore belong to operational technology (OT) environments rather than standard IT systems.

What is PLC?

A PLC (Programmable Logic Controller) is a computer used to automate industrial processes, such as water pumps or production lines.

A PLC is like an orchestra conductor – coordinating machines and sensors to achieve an operational "symphony."
