Field Bus Interface PROFIBUS DP (X71)

General Information

Pin Assignment

DOK-SUPPL*-VAM*10/40**-PR02-EN-P
Connector X71 provides at connection VP 5 V / 100 mA ISO voltage. Do
not use any bus terminating resistors, but only a bus load. Thus, the
connection of a hand-held terminal or an Optical Link Plug (OLP)
[conversion RS485/Opto] is possible.Optical PROFIBUS networks in ring
topology can be established with the help of the OLP.

Note: Ensure that potential equalizing currents don't flow over the
shield conductor of the interface line. Therefore, provide for a
proper potential equalization between the devices to be
connected already before the first commissioning.
