PLC, integrated PLC and HMI products are used in industrial automation systems for control, monitoring and operator interaction. Explore PLCs, compact PLCs with integrated displays and touchscreen HMI solutions suitable for machine automation, process control, production lines and control panel applications, and choose the right product based on I/O capacity, communication features, display configuration and your application requirements.
PLCs, integrated PLCs and HMIs are among the key components of automation systems used to control, monitor and operate machines, production lines and industrial processes. A PLC processes information received from sensors and other field inputs according to programmed control logic and controls outputs such as relays, motors, valves and similar devices. An integrated PLC combines PLC functions and a user interface within a single device. HMI operator panels visually display data from PLCs and other automation devices while allowing operators to interact with the system.
When selecting a product, factors such as the number of digital and analog I/O points, communication protocols, Ethernet and serial port options, expandability, processing capacity, and, for HMI applications, screen size and resolution should be considered. Depending on the scope of the application, you can choose a standalone PLC, an integrated PLC that combines PLC functionality and an operator interface in a single device, or a separate HMI operator panel.
Communication options such as Modbus RTU, Modbus TCP and Ethernet-based protocols are important for enabling PLCs, HMIs, drives, remote I/O modules and other automation equipment to communicate within the same system. Especially in compact machines and applications with limited control panel space, integrated PLC solutions combine control and visualization functions in a single device.
