AS-Interface

Introduction

Transmission technology

■Overview Transmission method

A significant feature of the AS-Interface technology is the use of a common, two-wire cable for data transmission and distribution of auxiliary power to sensors/actuators.

An AS-Interface power supply unit, which meets the require- ments of the AS-Interface transmission technology, is used for this system. The AS-Interface shaped cable provides mechani- cal coding and thus prevents polarity reversal; penetration terminals are used for simple contacting.

■Benefits

Cabinets that were previously overflowing with complicated con- trol line wiring and marshalling distributors can now be replaced by AS-Interface.

The AS-Interface cable can be connected at any point, thanks to specially developed wiring and connection using the insulation displacement method.

This concept gives you tremendous flexibility and considerably cuts costs.

The AS-Interface is a single master system. Communications processors (CPs) are available for SIMATIC® systems which control process or field communication as masters.

The system expansion now allows double the quantity of slaves (max. 62) to be operated on AS-Interface. The analog values are now also preprocessed in the master. For direct connection of AS-Interface to PROFIBUS DP, DP/AS-Interface Link 20E is available. Using this DP/AS-Interface link, the AS-Interface can be used as a subnet for PROFIBUS DP.

The AS-Interface is an open standard. Leading manufacturers of actuators and sensors support AS-Interface worldwide. Interested companies can obtain the electrical and mechanical specifications from the AS-Interface Association on request.
