Product Description for Siemens 6ES7972‑0BB70‑0XA0 PROFIBUS‑DP Bus Connector
1. Product Overview
6ES7972‑0BB70‑0XA0 is a new‑original Siemens SIMATIC DP 9‑pin D‑Sub bus connector designed for PROFIBUS‑DP field‑bus networks. It adopts Fast‑Connect insulation‑displacement contact technology and 90‑degree cable outlet design. This component connects standard PROFIBUS‑DP two‑core cables with PLC CPUs, ET200SP, ET200M remote I/O modules, communication processors and HMI panels. It establishes RS485‑based data links for S7‑300, S7‑400, S7‑1200 and PCS7 automation systems. A sliding‑switch‑controlled terminating resistor is built‑in to match PROFIBUS network impedance requirements at start‑points and end‑points of bus lines. The integrated PG programming interface allows engineers to connect laptops directly for online programming, hardware diagnosis and parameter downloading without disconnecting bus wiring. It is widely used in automotive production workshops, chemical plants, power‑station control systems, packaging lines and metallurgical automation facilities with PROFIBUS‑DP communication topologyRS Compone….
2. Main Functions
- Reliable Bus‑line Connection
Fast‑Connect piercing contacts cut through cable insulation without stripping wires manually, realizing stable electrical connection between PROFIBUS‑DP cables and 9‑pin D‑Sub interface of Siemens automation equipment. Built‑in strain‑relief structure prevents wire breakage caused by pulling or twisting on‑site.
- Integrated Termination Resistor
The internal 120‑ohm terminating resistor can be switched ON or OFF via sliding switch. When the connector is located at two endpoints of PROFIBUS‑DP network, users turn on the resistor to eliminate signal reflection and guarantee high‑speed data transmission quality. Middle‑position connectors keep the resistor turned‑off.
- PG Programming Interface
An independent programming port is reserved on the connector. Service staff can connect a programming laptop to download programs, monitor runtime data and diagnose faults without unplugging PROFIBUS‑DP trunk cables.
- Cascading Connection Support
Two‑way bus‑through design enables daisy‑chain wiring. One incoming cable and one outgoing cable can be wired on a single connector to form linear PROFIBUS‑DP topology and reduce wiring workload.
- Anti‑Interference Performance
Shield‑contact design connects cable shielding layer with PLC housing reliably to suppress electromagnetic interference generated by servo drives and high‑current actuators.
- Firm Mechanical Fixing
Screw‑locking mechanism fixes the D‑Sub plug tightly onto device ports to avoid loose connections under workshop vibration conditions. The PG‑thread receptacle provides firm cable‑clamping installationdocs.rs-on….
