The Siemens 6AG1972-0BA42-7XA0 is a SIPLUS DP PROFIBUS RS-485 bus connector based on the standard 6ES7972-0BA42-0XA0. It is designed to connect PROFIBUS stations to PROFIBUS bus cables in industrial automation networks.
The connector supports PROFIBUS DP transmission rates from 9.6 kbit/s to 12 Mbit/s and features a 35° inclined cable outlet. Two screw-terminal connections are provided for the PROFIBUS cable, while the station-side connection uses a 9-pin Sub-D interface. An integrated terminating resistor with isolating function can be selected using the slide switch. The SIPLUS version incorporates conformal coating and supports an extended operating temperature range of approximately -40 °C to +70 °C.

Technical FAQs
1. What is Siemens 6AG1972-0BA42-7XA0?
6AG1972-0BA42-7XA0 is a SIPLUS DP PROFIBUS RS-485 bus connector based on Siemens 6ES7972-0BA42-0XA0.
2. What is the main function of this connector?
It connects a PROFIBUS station to the PROFIBUS bus cable and provides the RS-485 electrical interface required for PROFIBUS communication.
3. What transmission rates are supported?
The connector supports PROFIBUS DP transmission rates from 9.6 kbit/s to 12 Mbit/s.
4. Does the connector include a programming-device socket?
No. The 6AG1972-0BA42-7XA0 is the version without a PG socket.
5. How is the PROFIBUS cable connected?
The PROFIBUS cable is connected through screw terminals, while the station-side connection uses a 9-pin Sub-D connector.
6. Does the connector include a terminating resistor?
Yes. An integrated resistor combination can be connected or disconnected using the slide switch and provides an isolating function.
7. What is the purpose of the terminating resistor?
The terminating resistor is used to properly terminate the PROFIBUS segment at the appropriate end of the bus and help maintain reliable RS-485 signal transmission.
8. What does the 35° cable outlet provide?
The 35° outlet positions the PROFIBUS cable at an inclined angle relative to the station connector, helping simplify cable routing where a straight or 90° outlet is less suitable.
9. What environmental conditions can the SIPLUS version withstand?
The connector has conformal coating and is specified for operation from approximately -40 °C to +70 °C. Siemens also specifies high humidity tolerance, including condensation and frost under the applicable conditions.
10. What should be verified before ordering this connector?
The PROFIBUS station interface, required transmission rate, cable type, connector orientation, terminating-resistor position, environmental requirements, and applicable Siemens documentation should be verified before ordering.
