A 35-degree PROFIBUS screw-terminal connector with a PG socket and switchable termination with an outgoing-bus disconnect function.
At a Glance
| Brand | Siemens |
|---|---|
| Model | 6ES7972-0BB41-0XA0 |
| Product Type | RS 485 bus connector |
| Core Function | Bus connection and programming access |
| Application | PROFIBUS device interfaces |
Programming access retained
The added PG socket provides access for a programming device at the installed bus connector.
Inclined cable routing
A 35-degree outlet routes the bus cable away from the device interface.
Selectable bus end
Switching on termination also disconnects the outgoing bus cable.
Product Overview
6ES7972-0BB41-0XA0 provides screw-terminal PROFIBUS wiring together with a local programming-device socket.
The inclined cable outlet and integrated termination suit an installed RS 485 node where commissioning access must remain available without removing the field-bus cable from its connector.
Key Functions
Connect a PG beside the permanent bus wiring
The programming socket carries the same pin assignment as the attached device through one-to-one contact connections.
Terminate a screw-wired segment
The bus conductors land at four screw terminals and the slide switch selects the integrated resistor network.
Isolate the outgoing cable at a bus end
Activating the terminating resistor disconnects the outgoing cable, making the selected connector the end of that segment.

Frequently Asked Questions
Can I attach a programming device at 6ES7972-0BB41-0XA0 without replacing the bus connector?
Yes, this version includes a PG socket for programming-device access.
What happens to the outgoing line when I switch termination on at 6ES7972-0BB41-0XA0?
The outgoing bus cable is disconnected when the integrated terminating resistor is activated.
Will the PG socket on 6ES7972-0BB41-0XA0 change the device pin assignment?
No, the programming socket contacts are connected one-to-one with the connector pins.
Can I unplug 6ES7972-0BB41-0XA0 from a terminating end node while the segment is operating?
No, removing a connector with active termination from a segment end disrupts the bus.
Which supply must the connected device provide for 6ES7972-0BB41-0XA0?
The connected device must supply 4.75–5.25 V DC with a maximum connector current demand of 5 mA.
Does 6ES7972-0BB41-0XA0 need the same cable exit space as a 90-degree plug?
No, its cable outlet is inclined at 35 degrees and needs clearance for that routing.
Can I install 6ES7972-0BB41-0XA0 at an ordinary interior node with termination enabled?
No, enabling its termination at an interior node disconnects the outgoing cable and makes following nodes inaccessible.
