• Connection of stations by means of integrated connecting cable with Sub-D plug.
• Easy connection of the bus cable by means of terminal block
• No interruption of bus if an end user station is missing
• Bus termination is possible by means of an integrated combination of terminating resistors.

The following additionally applies to the bus terminal 12M:

• Clear location of faulty termination within a segment (incoming and outgoing bus cables are separated when inserting the resistor combination)
• If the bus terminal 12M is used in a segment with RS485 bus terminals, the configuration rules of the RS485 bus terminal apply (see Manual for PROFIBUS Networks).

System connection with PROFIBUS bus terminals, e.g. for SIMATIC S7
