Fieldbus interfaces
Actuator controls with fieldbus interfaces
Fieldbus systems are increasingly used to connect process control systems and field devices when it comes to the automation of different tasks and processes in industrial environments. This development is based on the considerable cost reductions during planning and commissioning as well as during operation and maintenance of these systems. Smooth interaction of various field devices is ensured by open international fieldbus standards.
Due the modular AUMA design, all actuators available at AUMA can be equipped with a standardised fieldbus interface such as Profibus or Modbus.
Design principle :
Choosing from a modular system, consisting of actuator controls, fieldbus interfaces, the available transmission media and redundancy concepts, tailor-made solutions for every automation task can be found.
Various fieldbus interfaces are available for the actuator controls AUMATIC AC and AUMA MATIC AM.
