6.1.1 Connection to PROFIBUS DP
Connection to PROFIBUS DP 6- ][BA_Verdrahtung DP
The PSSu is connected to PROFIBUS DP via RS 485 communication.
The PSSu supplies the PROFIBUS DP bus terminating resistors with
voltage (+5 VDC).
 Connect the connector housing to the screening on the PROFIBUS
cable. The connector housing should be connected with low imped-
ance to the mounting rail.

INFORMATION
The two data lines are also called A and B on PROFIBUS.
Always connect the A-line (“RxD/TxD-N”) to the A-lines of all the
other PROFIBUS subscribers.
The B-line (“RxD/TxD-P”) should only be connected to the B-
lines of the other PROFIBUS subscribers.
If communication is not established, check the connections
using a continuity tester.
CAUTION!
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.
