Siemens 6GK1571-0BA00-0AA0 PC Adapter USB A2
A USB-powered adapter connecting a PG, PC or notebook to SIMATIC S7 over PROFIBUS or MPI.
Product Overview
6GK1571-0BA00-0AA0 is the Siemens PC Adapter USB A2. It provides an engineering connection from a USB-equipped PG, PC or notebook to SIMATIC S7 systems through PROFIBUS or MPI.
The adapter uses one 9-pin Sub-D RS-485 connection and one standard USB-B interface. It requires no optional external supply because operating power comes from the USB connection.
Compatibility planning must include the engineering computer, supported operating system and Siemens software release. The adapter establishes the physical communication path but does not replace project backups or access-control procedures.
