Note!
The Profibus line has to be terminated with its ripple resistor. Please make
sure to terminate the last participants on the bus at both end by activating
the terminating resistor.
In systems with more than two stations all partners are wired in parallel.
For that purpose, the bus cable must be feed-through uninterrupted.
Via the order number VIPA 972-0DP10 you may order the bus connector
"EasyConn". This is a bus connector with switchable terminating resistor
and integrated bus diagnostic.
