At a Glance
| Brand | Siemens |
|---|---|
| Model | 6ES7972-0BB51-0XA0 |
| Product Type | PROFIBUS bus connector |
| Core Function | Bus wiring with local programming access |
| Application | PROFIBUS RS 485 device interfaces |
Programming socket available
A PG can connect at the station through the added service socket.
Insulation-piercing contacts
The FastConnect arrangement terminates prepared PROFIBUS bus conductors.
Ten connection cycles
The insulation-piercing contacts have a defined limit for repeated connection work.
Product Overview
6ES7972-0BB51-0XA0 connects a PROFIBUS station through a 90-degree FastConnect cable outlet while retaining a local PG socket.
The integrated termination selects the end of a bus segment and disconnects the outgoing line when enabled, so wiring direction and switch position remain central to commissioning.
Key Functions
Connect prepared bus conductors
The insulation-piercing contact system makes the FastConnect bus-cable connections.
Provide programming access at the node
The PG socket carries the attached device’s pin assignment through one-to-one contact connections.
Establish the segment endpoint
The terminating resistor is activated at the first and last node and isolates the outgoing cable when switched on.

Frequently Asked Questions
How often can I remake the FastConnect contacts on 6ES7972-0BB51-0XA0?
The insulation-piercing terminals are designed for ten connection cycles.
Can I reuse the previously pierced cable end when reconnecting 6ES7972-0BB51-0XA0?
No, cut off the previously connected end before preparing and reconnecting the cable.
Where should the cable shield sit inside 6ES7972-0BB51-0XA0?
The exposed shield must lie directly on the connector’s contact element.
Will the PG socket of 6ES7972-0BB51-0XA0 reverse the device pin assignment?
No, all programming-socket contacts connect one-to-one with the connector pins.
Can I leave termination enabled on 6ES7972-0BB51-0XA0 at a through-wired interior station?
No, enabled termination disconnects the outgoing cable and must be used at the intended segment end.
Should the endpoint device powering 6ES7972-0BB51-0XA0 remain switched on during network operation?
Yes, a station supplying an active terminating resistor must remain powered during startup and operation.
Can I use 6ES7972-0BB51-0XA0 for the 90-degree FastConnect option on a compatible S7-300 PROFIBUS interface?
Yes, the connector is the 90-degree insulation-displacement version with a programming-device interface.
