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:
•
Connections between INTERBUS master interface module and first bus
terminal or first 2113 fieldbus module.
•
Connection between bus terminal and 2113 fieldbus module
•
Connection between two 2113 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
