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.
