Pos. Element Explanation

1 INTERBUS master with

interface module

The bus system is a master-slave system, i.e. an INTERBUS master is connected

to several field devices (slaves).

2 INTERBUS loop bus

terminal

The bus terminal connects a long distance bus to a peripheral bus.

3 Remote bus

Fig. 5.4-2 Pos. 3

The following connections are possible with remote buses:

• the INTERBUS master interface module and first bus terminal or first 2111

fieldbus module.

• the bus terminal and t he 2111 fieldbus module

• two 2111 fieldbus modules

3.1 Long distance bus module Bus participant in the long distance bus; e.g. Lenze controller with INTERBUS

module (slave). Networking does not require bus terminals.

3.2 Remote bus cable Connects the INTERBUS master interface module with the bus terminal and/or

the long distance bus modules.

4 INTERBUS loop, peripheral

bus

Fig. 5.4-2 Pos. 4

Connection in a peripheral-bus station

A peripheral-bus station consists of:

• a bus terminal (Fig. 5.4-2 pos. 2)

• up to eight peripheral bus modules (Fig. 5.4-2 pos. 3)

4.1 INTERBUS loop module Bus participant in the INTERBUS loop; e.g. Lenze controller with INTERBUS loop

module 2112

4.2 INTERBUS loop cable Connection within the loop
