6ES7972-0BB12-0XA0 | PROFIBUS DP Bus Connector with PG Port, 90° Cable Outlet
6ES7972-0BB12-0XA0 PROFIBUS DP / MPI bus connector (RS485). 90° cable outlet, integrated PG/diagnostic port, screw terminals, for S7-300/400/ET 200M networks up to 12 Mbps.

Product Overview

The  6ES7972-0BB12-0XA0​ is a PROFIBUS DP / MPI RS485 bus connector (sub-D 9-pin)​ used to terminate and interconnect nodes in a  SIMATIC S7, S5, or ET 200 distributed I/O network. It features a 90° (right-angle) cable outlet, integrated PG/PC diagnostic port (AUX)​ for online monitoring without disconnecting the bus, and screw terminals for quick cable shield/drain wire termination. This is the standard bus connector for PROFIBUS segments running at up to 12 Mbit/s.

Key Features

  • PG/PC Diagnostic Tap:​ The auxiliary AUX port lets you connect a PG/PC or analyzer to the live bus without breaking the segment — essential for commissioning and troubleshooting.
  • 90° Low-Profile Design:​ Right-angle cable exit saves space in shallow cabinets or tight rack groupings vs. the 35° variant (6ES7972-0BA12-0XA0).
  • Screw Shield Termination:​ Dedicated drain wire screw terminal ensures proper shielding practice per EN 50174 — no crimp ferrule needed for shield.
  • Ecosystem Native:​ Direct plug-in to CPU 31x/41x MPI/DP ports, CP 5611/5621 cards, IM 153-2 DP interfaces, and Y-Link repeaters.

Applications

  • PROFIBUS DP Network Build:​ Connecting S7-300/400 CPUs, ET 200M/ET 200S stations, drives (G120/G130 with PROFIBUS option), and HMI panels into a multi-drop RS485 segment.
  • MPI Programming Link:​ Temporary PG connection to S7-300/400 CPUs for STEP 7 download/upload via the AUX port.
  • Bus Troubleshooting:​ Tapping live segments with a laptop running SIMATIC NET or third-party PROFIBUS analyzers.
  • Legacy S5 / S7 Hybrid Networks:​ Also compatible with MPI protocol (up to 187.5 kbps S7, 1.5 Mbps S5) for mixed-vintage plants.
Note: For the 35° cable outlet​ version (more common in deep cabinets), see 6ES7972-0BA12-0XA0​ (no PG port) or 6ES7972-0BB41-0XA0​ (35° with PG port — newer FastConnect design). Bus termination​ is applied at the two end nodes using either a built-in DIP switch (on -0BA50/-0BB50 variants) or a 6ES7972-0BA50-0XA0 terminator plug​ on the last connector's AUX port. Always use screened PROFIBUS cable (e.g., 6XV1830-0EH10) and connect the shield to the designated screw terminal.
