Fieldbus technology is rapidly gaining acceptance and integration into automation applications worldwide. Based on network topology, system requirements and performance, various types of fieldbus systems are available, all developed and supported by individual standardization organizations. The key principle of fieldbus technology is to enhance device functionality, achieve communication transparency, simplify and standardize installations, as well as limiting the installation and maintenance costs. Sensors, like encoders, with support for various fieldbus interfaces have been available for several years and are increasingly gaining in acceptance and installed market share.
