Siemens 6GK7343-2AH00-0XA0 Profibus DP Interface

Siemens CP 343-2 Communications Processor, article number 6GK7343-2AH00-0XA0, provides a PROFIBUS DP interface with AS-Interface connectivity for SIMATIC S7-300 systems. It is designed to connect SIMATIC S7-300 and ET200M to AS-Interface networks, functioning as a DP/AS-i LINK Advanced module (V2.2) with DPV0 and DPV1 modes, enabling DP master communication to AS-i devices over a single PROFIBUS DP bus. This CP 343-2 module sits within the SIMATIC NET family and is used to bridge PLCs with AS-i sensors and actuators in industrial automation environments, supporting DP-based control of AS-i networks. The product is discontinued and no longer supported past its lifecycle date of July 1, 2010, so remaining units are typically available only through used-equipment vendors, with variant 6GK7343-2AH01-0XA0 representing related configurations.
