Specification

The SIEMENS SIMATIC S7-200 USB/PPI Cable, model 6ES7901-3DB30-0XA0, is a dedicated programming interface designed for seamless connectivity between a PC and S7-200 PLCs. This cable converts USB signals to RS485 for PPI protocol communication, enabling fast program uploads, downloads, and online diagnostics. It is ideal for maintenance engineers and system integrators working with legacy S7-200 systems, offering a compact, portable solution without the need for a separate MPI adapter. The cable supports baud rates from 9.6 kbps to 187.5 kbps, ensuring compatibility with various S7-200 CPU models, including CPU 21x and CPU 22x series. Its built-in galvanic isolation protects both the PC and PLC from voltage spikes, making it suitable for harsh factory floors. The USB interface is fully compliant with USB 2.0 standards and backward compatible with USB 1.1, while the RS485 side uses a standard 9-pin D-sub connector for direct attachment to the PLC’s programming port. This product is manufactured under strict SIEMENS quality controls and is shipped with a 12-month warranty.
