General Information about INTERBUS-Configuration

Construction of a

Tree Structure

This example shows a tree structure using branch interface modules on the

INTERBUS. Each branch interface module is a remote bus node and enables the

connection of a remote bus branch to the remote bus. Using a tree structure, the bus

can be matched to the local requirements. Cabling expenditure can be considerably

reduced in this way.
