Bus connector
The bus connector is used to connect the PROFIBUS cable to the PROFIBUS DP interfaces (X8,
X9), thus establishing a connection to additional nodes.
The following bus connectors are available:
• Up to 12 Mbits/s, cable outlet 90°
– Without PG socket (6ES7 972-0BA12-0XA0 or 6ES7 972-0BA50-0XA0)
– With PG socket (6ES7 972-0BB12-0XA0 or 6ES7 972-0BB50-0XA0)
• Up to 12 Mbits/s, canted cable turn
– Without PG socket (6ES7 972-0BA41-0XA0)
– With PG socket (6ES7 972-0BB41-0XA0)
Inserting a bus connector in a module
Proceed as follows to connect the bus connector:
1. Plug the bus connector into the module.
2. Screw the bus connector tightly onto the module.
3. If the bus connector is located at the start or the end of a segment, you must connect the
terminating resistor ("ON" switch setting) (refer to the following figure).
Make sure that the nodes at which the terminating resistor is located are always supplied with
voltage during startup and operation.
