Extend Your PROFIBUS Network with the Compact MULTIrep X2 Repeater
Using a repeater allows an enlargement of your PROFIBUS network until up to 126 devices and to create higher line lengths depending on the fieldbus transmission speed. Per segment, a maximum of 32 devices (31 + repeater) is acceptable. The MULTIrep produces a voltage signal in two, five or seven directions (depending on the version) and raises the signals to the PROFIBUS standard level.
From the physical point of view the MULTIrep provides up to seven isolated segments. The integrated diagnosis via LED allows for simple troubleshooting in each segment.
MULTIrep X2 Advantages
Basis for a stable PROFIBUS star structure
Enables stubs in PROFIBUS
Isolates sensitive or problematic areas
Expansions or shutdowns possible during running operation.
Errors affect only small parts of the network.
Fieldbus connection and termination
PROFIBUS is connected by a 9 pin sub-D socket (according to PROFIBUS guideline). If the segment ends or starts directly at repeater terminals, bus termination resistors have to be activated directly at the plugs.
Instruction for use
Using the MULTIrep creates up to seven galvanically isolated segments. For the purpose of diagnostic measurements a measuring point should be provided at the beginning and end of every segment. Therefore, the PG interfaces at the 9-pin sub-D plugs can be used as measuring points.
If a segment ends or begins directly at the connections of the repeater, it is necessary to activate the bus terminating resistors at the plugs.

PROFIBUS brochure
PROFIBUS has proved itself in the industrial practise as a reliable and stable network. The brochure PROFIBUS – Rediscover proven technology describes the basic technological coherence's in compact form and indicates important quality standards. It is also presented how they can be checked and monitored reliably.
