Controllers & HMIs

A PLC is an industrial digital computer designed to control manufacturing processes, such as assembly lines, machines, or robotic devices.
It monitors inputs, makes decisions based on its programmed logic, and controls outputs to automate complex processes in real time.
An HMI is a user interface or dashboard that connects a person to a machine, system, or device. In automation systems, HMIs are used to visualize data, control equipment, and monitor system status.
They typically display alarms, process trends, and diagnostics, enabling operators to interact with the PLC and the broader control system.
