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 the 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
