Using RS-485/RS-422 Transceivers in Fieldbus Networks


Abstract: RS-485 transceivers offer an easy way to implement the physical layer in industrial networks; several fieldbus standards specify an RS-485 serial port for communications. This article describes several fieldbus technologies and gives special attention to the INTERBUS and PROFIBUS networks .Some particularly useful features of RS-485 transceivers are highlighted.
