- Backward Compatible: Works with legacy S7-300/400 installations as well as current S7-1500 systems.
System Architecture & Signal Flow
The 6GK1571-0BA00-0AA0 operates as a transparent protocol bridge between the USB host (engineering PC) and the PROFIBUS DP segment:
- USB Host Interface: The adapter enumerates as a virtual COM / HID device on the PC. SIMATIC NET drivers abstract this into a standard S7ONLINE / DP interface accessible by STEP 7 and TIA Portal.
- Internal Protocol Conversion: An embedded microcontroller handles PROFIBUS DP framing, token passing, and baud rate negotiation autonomously.
- RS-485 Physical Layer: The 9-pin Sub-D connector interfaces directly to the PROFIBUS DP bus cable (shielded twisted pair, 150 Ω termination).
- Galvanic Isolation Stage: Optical isolation between USB and RS-485 domains prevents ground loops and protects the PC from field-side transients.
- Bus Termination: The adapter includes a switchable bus terminator; activate when the adapter is at either physical end of the PROFIBUS segment.
Sourcing & Quality Verification
- Origin: Sourced from authorized SIEMENS distribution channels and verified surplus stock with full traceability.
