Innomatic is offering the Bihl + Wiedemann AS-I gateway with graphical display. The device is a high-end solution to link AS-Interfaces with a superior fieldbus system. The AS-I Gateway features one or two AS-I Masters (in accordance with the new 2.1 specification) as well as an interface to the Profibus and DeviceNet system.

Programming or changing AS-I slave addresses is made easy through the user interface graphical display. Slaves can now be easily addressed directly on the gateway. For shortened commissioning time or faultfinding, digital and analog I/Os can be directly activated or read from the AS-I gateway without the controller/PLC being connected.

The AS-Interface gateway has a built-in AS-I scope function that monitors the integrity and quality of the AS-I communications. The onboard scope continuously checks for transmission errors, the graphical display allows for realtime information to be read at a glance. Each slave has an error counter that can be reset and can give an early indication of any network or slave problems. The analog I/Os are controlled by the gateway without the requirement of any special configuration. Advantages offered by this user-friendly system include significant savings in time and costs.
