10.2.3.1 Bus Termination
The Profibus must be terminated electrically in order to prevent interferences. For
this reason each bus "participant" permits "passive" termination of the bus (see figure
below). Usually, this terminal is integrated into the connector of the cable of the Profi-
bus (connectors from ERNI or SIEMENS) and must be provided at both "sides" of the
bus.
