AS Interface The Fieldbus for Low Level Automation
Peter Janssen · Proceedings of the JFPS International Symposium on Fluid Power · 1999
Consistent communications have always been striven for throughout the entire scope of any given automation solution. However, this has only been possible to a limited extent. A possibility which allows for communication with the lowest level, i.e. the sensor and actuator level, has usually been lacking.The AS interface, recognisable by its characteristic yellow cable, places an “open bus system” for the interconnection of simple, binary sensors and actuators at the disposal of the user which allows for communications all the way down to the sensor and actuator level. The AS interface has firmly established itself within the market with further advantages such as real-time capabilities and reliable data transmission, as well as easy installation thanks to modular design and use of the penetration technique.Through the use of an applications example, the following paper demonstrates the demands placed on the AS interface by customers, as well as data security measures.
