Verified product identity and procurement-focused technical information
Siemens 6GK7343-2AH01-0XA0 is the SIMATIC NET CP 343-2 communication processor for connecting SIMATIC S7-300 and ET 200M stations to AS-Interface networks. Siemens specifies AS-i version 3.0, master profile M4, one AS-i interface and configuration through the SET pushbutton, STEP 7 or the command interface. The module uses an S7-300 20-pin front connector and can support redundant operation with a redundant IM 153 arrangement. Replacement planning should verify the complete suffix, front connector, firmware, AS-i power concept and project configuration. Siemens lists this article under PM400 product phase-out.
