The 6AG1901-3CB30-2XA0: This is the SIPLUS variant of the standard S7-200 PPI cable (6ES7901-3CB30-0XA0), rated for -25...+70°C ambient. It communicates via PPI at 10/11 bit or ASCII Freeport protocol, with baud rates selectable via DIP switch up to 187.5 kbit/s. Power is drawn from the CPU port; no external supply needed. Three LEDs show Tx (RS-232), Rx, and PPI (RS-485) activity, which helps during commissioning and fault isolation.
