A programmable controller (PLC) has a microprocessor and controls devices through custom user programs. A PLC receives signals from input devices and makes decisions based on custom programs to control output devices. Ladder logic is a graphical programming language and commonly used for PLC programming. One of the leading makers of compact PLCs for machine automation is Omron PLC. Omron offers a flexible line of scalable industrial PLC controllers for use in single machines or as part of larger machine control installation. A programmable logic controller (PLC) is a small, modular solid state computer with customized instructions for performing a particular task. PLCs, which are used in industrial control systems (ICS) for a wide variety of industries, have largely replaced mechanical relays, drum sequencers and cam timers.
CX-Programmer, the programming software for all Omron’s PLC series, is fully integrated into the CX-One software suite. CX-Programmer includes a wide variety of features to speed up the development of your PLC program. PLCs communicate, monitor and control automated processes like assembly lines, machine functions, or robotic devices. A PLC’s functions are divided into three main categories: inputs, outputs and the CPU. PLCs capture data from the plant floor by monitoring inputs that machines and devices are connected to.
These three PLC components are: processor, power supply, and an input/output (I/O) section. The processor, or the brain of the PLC system, is a solid-state device designed to perform a wide variety of production, machine tool, and process-control functions. PLCs are used in various applications in industries such as the steel industry, automobile industry, chemical industry and the energy sector.
