Connector X71 provides at the VP connection 5 V / 100 mA ISO voltage. Do
not use any bus terminating resistors, but only a bus load. Thus, a hand-held
terminal or an Optical Link Plug (OLP) [conversion RS485/Opto] can be con‐
nected.
Optical PROFIBUS networks in ring topology can be established by the OLP.
