Selection Notes

The USB-powered design, 5V at 0.2A from the USB port, means no external power supply is needed at the PC side, useful for field service laptops connecting to an S7-300/S7-400 MPI or PROFIBUS port without carrying a separate adapter power brick. The bundled 5 m USB cable and 0.3 m MPI cable set the practical reach between the laptop and the PLC programming port.

Applications

Used by commissioning and service engineers to connect a notebook running STEP 7 or TIA Portal to SIMATIC S7 CPUs over PROFIBUS or MPI for programming, diagnostics, and firmware updates.
