PLCohjausten

PLCohjausten is a term commonly used in Finnish industrial automation contexts. It refers to the control systems that utilize Programmable Logic Controllers (PLCs). PLCs are ruggedized industrial computers designed for controlling manufacturing processes, such as assembly lines, robotic devices, or any activity that requires high reliability control and ease of programming.

A PLCohjausten system typically consists of a PLC unit, input modules, output modules, and a human-machine interface (HMI) for monitoring and operator interaction. Input modules receive signals from sensors and devices in the field, such as limit switches, temperature sensors, or pressure transmitters. The PLC processes these input signals based on a programmed logic, which is often written in ladder logic, function block diagrams, or structured text. The output modules then send control signals to actuators, such as motors, solenoids, or indicator lights, to affect the process.

The primary advantages of PLCohjausten systems lie in their flexibility, reliability, and scalability. They can be easily reprogrammed to accommodate changes in production requirements, unlike hard-wired relay logic systems. Their robust construction ensures operation in harsh industrial environments, and they can be expanded with additional modules to handle more complex tasks. PLCohjausten are fundamental to modern industrial automation, enabling efficient and automated operation of a wide range of processes.
