The two data lines are also called A and B on PROFIBUS.
Always connect the Aline ("RxD/TxDN") to the Alines of all the other
PROFIBUS subscribers.
The Bline ("RxD/TxDP") should only be connected to the Blines of the
other PROFIBUS subscribers.
If communication is not established, check the connections using a continu
ity tester.

Connect the connector housing to the shielding on the PROFIBUS cable. The con
nector housing should be connected with low impedance to the mounting rail.

Do not use the signals VP (+5 V ext.) and DGND (GND ext.) to supply
voltage to external devices! They are exclusively used to supply the
PROFIBUS DP bus terminating resistors.
