Specification

The SIEMENS SIMATIC S7-200 PC/PPI Cable, designated as 6ES7901-3CB30-0XA0, is an essential communication interface for industrial automation engineers. This cable enables seamless connectivity between a PC (typically via a serial RS232 port) and the S7-200 PLC family, using the PPI (Point-to-Point Interface) protocol. Designed for programming, monitoring, and troubleshooting, it eliminates the need for additional converters or external power, making it a cost-effective and compact solution for field service and lab setups. The cable is fully shielded to minimize electromagnetic interference, ensuring stable data transmission even in electrically noisy environments. Below is a comprehensive specification table based on industry-standard data for this model.
