6ES7972-0BB41-0XA0 SIMATIC PROFIBUS 35° Screw Bus Connector with PG Socket

A 35-degree PROFIBUS screw-terminal connector with a PG socket and switchable termination with an outgoing-bus disconnect function.

Ad Primum Aspectum

Nota	Siemens
Modellum	6ES7972-0BB41-0XA0
Typus Producti	RS 485 bus connector
Functio principalis	Bus connection and programming access
Applicatio	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.

Focus ordinandi: Retain the PG-socket version and verify the inclined cable clearance, cable diameter and termination-switch position for the node’s place in the segment.

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.

Quaestiones Frequenter Rogatae

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?

Apparatus coniunctus 4.75–5.25 V DC praebere debet, cum maxima corrente connectoris 5 mA.

Num 6ES7972-0BB41-0XA0 eundem spatium pro exitu cavi requirit atque connexio anguli recti?

Non; eius exitus cavi inclinatus est ad angulum 35 graduum et spatium pro hac directione necessarium est.

Num 6ES7972-0BB41-0XA0 in nodo interiori ordinario cum terminatione activata installare possum?

Non; si terminatio in nodo interiori activatur, catena egrediens interrumpitur et nodi subsequentes inaccessibiles fiunt.

Compatibility & Ordering Notes

Antequam 6ES7972-0BB41-0XA0 ordinatur: Hunc connexorem terminalis obliquae sceles, ubi connexio PG in statione opus est, et primum ac ultimum nodum in singulis segmentis cum potestate et terminatione correcta serva.

Index Compatibilitatis pro 6ES7972-0BB41-0XA0

• Spatium pro exitu cavi ad angulum 35 graduum et pro ductu PG relinquere oportet.
• Diametrum cavi destinatum et magnitudinem conductoris terminalis obliquae uti oportet.
• Permitte terminatio solummodo ad extremitates segmenti.
• Mantene apparecchium extremum coniunctum in statu activo dum eius terminatio necessaria est.
