The Siemens 6ES7-972-0BB12-0XA0 Backplane Bus Connector is a PROFIBUS DP connection module with an integrated PG interface, designed to connect a programming device to a Siemens backplane without interrupting the DP network. It provides a switchable termination resistor for the bus and is compatible with copper PROFIBUS fieldbus cables such as 6XV1 830-0AH10. The set includes two bus connectors, enabling quick deployment in SIMATIC PROFIBUS DP configurations that link DP devices to the backplane while preserving network operation and providing a dedicated programming path.
