The recipient of a bachelor of science in electrical engineering from the University of Southern California, Dianoush Emami is a former electrical engineer at Bechtel Corporation. Dianoush Emami has written manuals for Human Machine Interface (HMI) and has also reviewed manufacturing design for control systems.
Also known as a programmable logic controller, PLC lacks a mouse, monitor, and a keyboard, and it runs a system or machine connected to it through pre-programmed instructions. Human Machine Interface (HMI), on the other hand, has a monitor and user interface (either keyboard or touchscreen buttons) that allows a human operator to adjust the data and software process directly. Although both HMI and PLC have similar industrial applications, both systems differ in many features.
In PLC, unit display of ongoing processes is not available to operators; hence, operators cannot interact directly with the built-in program of PLC. Often, the program can only be edited once the PLC is connected to another device, such as a PC. HMI, on the other hand, has a unit display that enables operators to monitor ongoing processes during program execution, and also have a user interface with function buttons that operators can use to control processes. Due to the absence of a built-in interface, PLC can only handle automated operations, while HMI, on the other hand, can be used for both manual and automated tasks.
