PLCohjausjärjestelmät
PLCohjausjärjestelmät, or PLC control systems, are fundamental to modern industrial automation. A PLC, or Programmable Logic Controller, is a specialized industrial computer designed to control manufacturing processes. These systems are built to withstand harsh environments, including extreme temperatures, moisture, vibration, and electrical noise. They operate by continuously scanning input signals from sensors, executing a user-programmed logic, and then controlling output devices such as motors, valves, and actuators.
The core of a PLC control system is its processor, which executes the control logic. This logic
PLC control systems offer significant advantages over older relay-based systems. They provide greater flexibility, allowing for
