connector does not provide a service socket, you can plug in the D sub adapter cable
underneath. Keep in mind that you should never cascade more than two D-sub
connectors (see also
).
When using M12 connection technology, the M12 adapter cable is "looped" into the bus. It
is essential to ensure proper termination at the beginning and at the end of the bus by
using the terminating resistor provided with the M12 adapter set.
Shut down complete installation before connecting
Shut down the PLC and all the devices connected to the PROFIBUS as all
these simple connection types will divide the bus.

Connection for testing a live bus (DP)
To test a live PROFIBUS with the PROFIBUS Tester 5 during operation, appropriate
connection possibilities have to be provided. If no suitable connection points are available
in the existing installation, it is recommended to install them during system shutdown. This
will make future maintenance work much easier.
