About the Siemens 6ES7972-0BA12-0XA0

The Siemens 6ES7972-0BA12-0XA0 is a SIMATIC DP bus connector: the 9-pin sub-D plug that joins a PROFIBUS DP station to the RS 485 bus cable. It takes the incoming and outgoing bus cable on screw terminals, has a 90° (right-angle) cable outlet, and has no programming (PG) socket. A slide switch brings in the integrated terminating resistor; Siemens specifies it with an isolating function, so switching the resistor on at the end of a segment disconnects the outgoing cable. Siemens rates it for 9.6 kbit/s to 12 Mbit/s, IP20, and gives its size as 15.8 x 64 x 35.6 mm (W x H x D).

What is the 6ES7972-0BA12-0XA0 used for?

It plugs into the PROFIBUS DP port of each station on the bus: PLC CPUs and communication modules, distributed I/O, drives and operator panels. Every station needs one; the first and last connector on a segment have the terminating resistor switched on.

Before you order

What to photograph or confirm so the right unit is quoted.

Check the order number on the connector's label. Confirm the cable outlet angle (90°), whether there is a PG socket on the back, and the terminal type (screw). It is Siemens's named successor to the discontinued 6ES7972-0BA11-0XA0, which SiePortal lists as 15.8 x 54 x 34 mm: check the space in the cabinet before swapping.
