An industrial control computer, also known as an industrial PC or IPC, is a specialized computer designed to operate in industrial environments and perform control functions. It is used to manage and monitor industrial processes, machinery, and automation systems. These computers are built to withstand harsh conditions such as extreme temperatures, dust, vibration, and electromagnetic interference that are commonly found in industrial settings.
The concept of using computers for industrial control dates back to the mid - 20th century. Initially, large mainframe computers were used in some industrial processes, but they were expensive and not very suitable for the factory floor. As microprocessor technology advanced in the 1970s and 1980s, smaller and more affordable industrial control computers began to emerge. These early IPCs were used mainly for simple process control and data logging. Over time, with the development of more powerful processors, advanced operating systems, and rugged hardware designs, industrial control computers have become more versatile and capable of handling complex automation and control tasks in a wide range of industries.
Industrial control computers operate based on the principles of computer - based control systems. They have input/output (I/O) interfaces that allow them to communicate with sensors, actuators, and other industrial devices. The computer's central processing unit (CPU) processes the data received from the inputs according to pre - programmed algorithms and control logic. It then sends output signals to the actuators to control the industrial process. The software running on the IPC, which can range from simple ladder logic programs to complex custom - developed applications, determines the specific control actions and decision - making processes.
