7.2.2 Bus connector
Purpose of the bus connector
The bus connector is used to connect the PROFIBUS bus cable to the
PROFIBUS DP interfaces (X8, X9). This is how you make the connection to other
nodes.
The following bus connectors are available:
S Up to 12 Mbit/s, cable outlet 90_
– Without steel conduit thread socket (6ES7 972-0BA11-0XA0 or
6ES7 972-0BA50-0XA0)
– With steel conduit thread socket (6ES7 972-0BB11-0XA0 or
6ES7 972-0BB50-0XA0)
S Up to 12 Mbits/s, angular outgoing cable
– Without steel conduit thread socket (6ES7 972-0BA40-0XA0)
– With steel conduit thread socket (6ES7 972-0BB40-0XA0)
