Embedded HMIs excel in automation applications

摘要

The ways we interact with our phones, vehicles, and automation systems have been generalized as human-machine interfaces (HMIs). Using a car, for example, HMIs have progressed over the years from mechanical (manual transmission stick shift), to electrical (headlight switch), to digital (touchscreen navigation controls). Digital systems appear to be the highest evolution of the HMI, and there are a few ways to implement these types of interfaces. For today's industrial automation systems, users generally have two options for digital HMIs installed on the plant floor. They can select dedicated HMIs, also known as embedded HMIs, built for purpose. Or, they can choose standard or industrial PCs (IPCs) running more general operating systems (OSs) and IPC-based HMI applications.
