KL6201, KL6211 - Introduction

The AS Interface master terminal enables the direct connection of AS-i slaves. The AS-i compliant interface supports digital and analog slaves, versions 2.0 and 2.1. Process data exchange, parameterization and the diagnosis are fieldbus-independent. Together with the different Bus Couplers available from BECKHOFF, the KL6201 represents a universal fieldbus/AS-i gateway.

The size of the process image can be set to 6 bytes, 12 bytes (default), 22 bytes or 38 bytes, as required.

Since the usual register interface (with 64 registers per terminal or channel) is not sufficient for transferring all the information of the AS-i master terminal (terminal registers and AS-i parameters), a parameter interface was defined that can be accessed cyclically (via the process image) or acyclically (via fieldbus-specific acyclic services).
