Siemens SIMATIC NET PROFIBUS manual DP/AS-Interface Link

Topologies of SIMATIC NET PROFIBUS Networks

Uses

The DP/AS-interface link connects the PROFIBUS-DP fieldbus with the AS-interface. The DP/AS-interface link 65 can be connected to any PROFIBUS-DP master capable of handling parameter assignment and diagnostic frames with a length of 32 bytes. The DP/AS-interface link 65 allows the actuator-sensor interface to be used as a subnet for PROFIBUS-DP. You can therefore combine the advantages of PROFIBUS-DP and AS-interface in a common bus system.
