- Transfer rate: 9.6 kbit/s to 12 Mbit/s (PROFIBUS)
- Interface 1 (PROFIBUS): 9-pin Sub-D socket (RS 485)
- USB interface: Standard-B socket, USB 2.0
- Supply voltage: 5 V DC from USB (5% tolerance)
- Current consumption: 0.2 A from USB
- Power loss: 1 W
- Ambient temperature: 0 to 60 °C (operation), -40 to +70 °C (storage/transport)
- Relative humidity: 95% max at 30 °C (operation)
- Protection class: IP20
- Dimensions (W×H×D): 58 mm × 26 mm × 105 mm
- Net weight: 0.365 kg
One standout feature is the port diagnostics function, which helps you quickly verify the link status—crucial for troubleshooting on the shop floor.
Real-World Applications
For example, a technician can connect a laptop to a PLC in a control cabinet via PROFIBUS to upload new logic or monitor live data. The 5 m USB cable offers flexibility, while the 0.3 m MPI cable suits tight spaces.

Installation and Setup
Setup is straightforward: connect the USB cable to your PC and the MPI cable to the PLC's PROFIBUS/MPI port. The adapter is powered directly from the USB port—no external supply needed. It works with Windows XP, Vista, and Windows 7 (32/64-bit) and higher. Ensure the correct drivers are installed for your operating system.
Maintenance and Reliability
With no moving parts and a robust IP20 enclosure, the 6GK1571-0BA00-0AA0 requires minimal upkeep. Periodically inspect the cables and connectors for wear, and keep the adapter within the specified temperature and humidity ranges to ensure long-term reliability.
Solving the Connectivity Challenge
When an engineer needs to program a SIMATIC S7 controller but the PC lacks a PROFIBUS port, the 6GK1571-0BA00-0AA0 from Siemens bridges the gap. This USB adapter (USB V2.0) provides a reliable link from a PG/PC or notebook to SIMATIC S7 via PROFIBUS or MPI. It includes a 5 m USB cable and a 0.3 m MPI cable, so you can start working immediately.

Compatibility and Integration
The adapter is designed for SIMATIC S7 PLCs via PROFIBUS or MPI networks. It supports transfer rates from 9.6 kbit/s up to 12 Mbit/s, making it compatible with most PROFIBUS installations. The USB 2.0 interface ensures broad PC compatibility.
Troubleshooting Common Issues
If the connection fails, first verify that the USB cable is securely attached and the PC recognizes the adapter. Check the PROFIBUS address and transfer rate settings in your programming software—they must match the PLC's configuration. Use the port diagnostics feature to confirm signal presence.
