Connection arrangement for field bus systems has repeater electronics for continuing internal bus line of first unit module to second unit module and switching data flow directions

摘要

The arrangement has internal bus lines with at least one unidirectional and at least one bi-directional data line. At least one of the connection modules of the first and/or second units has repeater electronics for continuing the internal bus line of a module of the first unit to a module in the second unit and for switching the data flow directions between the different units.
