Service Interface for PROFIBUS DP
3.5.1
Connection Type D-sub
The D-sub service interface provides a PROFIBUS access point for testing if
the existing D-sub connectors have no service socket or if the bus stations are
connected via a terminal block. The service interface can power the
terminating resistor of the D-sub connector. You can thus use it as an active
bus termination at the beginning or end of the bus.
If the PLC allows dropping and adding bus stations on the live bus, you will
need this external bus termination to be able to exchange the first and last bus
stations without causing problems on the bus.
The compact unit is rail mounted like a terminal block and powered by an
external 24 VDC power supply. The package includes an 90° angled
PROFIBUS connector with a switchable terminating resistor.
