15.13 Network topology of a büS/CANopen system
When installing a büS/CANopen system, ensure that the terminating circuit of the data lines is correct. The
circuitpreventstheoccurrenceofinterferencecausedbysignalreectioninthedatalines.
Thetrunklinemustbeterminatedatbothendswith120Ωresistorsand1/4Wpowerloss-see“Fig. 43:
Networktopology-büS/CANopen”.
“Fig.43” illustrates a line with one trunk line and several drop lines. Trunk lines and drop lines consist of
identical material.
AuniqueNodeID(büS/CANopenaddress)canbeallocatedtoeachcontrolheadviaDIPswitches-see
chapter “15.14ConguringtheNodeID/baudrate”).
