Siemens 6ES7158-0AD01-0XA0 plc Controller

The Siemens 6ES7158-0AD01-0XA0 is a DP/DP Coupler from the SIMATIC DP family, designed to connect two independent PROFIBUS DP networks for data exchange. It functions as a two-sided PROFIBUS slave, allowing two DP masters to communicate with each other without requiring detailed checks of the PROFIBUS address fields on either side . The coupler is ideal for implementing communication between two separate machines or control systems, and it supports redundant current infeed for increased availability. The module is classified under Siemens PLM status PM300: Active Product, with a product phase-out planned effective October 1, 2026 .
