SIMATIC NET / AS-INTERFACE
AS-Interface master communication processor for S7-300 and ET 200M
Siemens 6GK7343-2AH11-0XA0 is the SIMATIC NET CP 343-2P communications processor for connecting SIMATIC S7-300 and ET 200M stations to AS-Interface. The P version adds expanded configuration options while retaining the CP 343-2 functionality. Siemens documents configuration through the SET key or STEP 7 and conformity with AS-Interface Specification V3.0. Exact rack fit, front-connector choice, addressing and the AS-i device plan must be reviewed before replacement.
