Cost reduction is one of the main factors in favour of fieldbus technology. In addition, introduction of serial communication in process automation has proven as an innovation driver for fi eld devices and consequently for actuators. Concepts for efficiency gains such as remote parameterisation or Plant Asset Management would not be feasible without fieldbus technology.
AUMA actuators equipped with fieldbus interfaces are state of the art.
Many different fieldbus systems are available on the market. Certain preferences have evolved on a regional level or specific to certain plant applications. Since AUMA actuators are implemented in all types of process plants around the globe, they are available with any fieldbus system established in this industry.
Overall, AUMA devices are available with binary and analogue inputs to connect additional sensors to the fieldbus.
