This application report focuses on the benefits of using RS-485 signaling for motor control and motion control applications. This technology has several benefits for these applications in terms of noise immunity, wide common-mode voltage range, adequate data rate, and multipoint capability. Other applications also use RS-485 signaling to take advantage of these same benefits. Applications such as process control networks, industrial automation, remote terminals, building automation and security systems apply RS-485 extensively to solve their requirements for robust data transmission over relatively long distances.
