Seamlessly replace Siemens PROFIBUS repeaters — faster diagnostics, better isolation, & free support. The MULTIrep X7 is your future-ready solution — a diagnostic PROFIBUS repeater designed for stable, scalable, and serviceable networks. Improve long-distance communication, isolate problematic segments, and diagnose issues instantly with built-in LED indicators. Perfect for star topologies or high-performance PROFIBUS builds.



Overview

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.


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.


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.

MULTIrep: Features and benefits in detail

Signal regeneration for trouble-free data communication

With the MULTIrep repeaters, the voltage signal required for data communication is regenerated in both line directions and raised to standard PROFIBUS level. However, the signal content remains unchanged, ensuring smooth data communication in large segments and/or long cable runs.

Stable star structure possible

With the MULTIrep PROFIBUS repeater series, it is possible to divide your network into two, five, or seven galvanically isolated segments, depending on the expansion stage. As a result, local, functional, or technological groups can be formed depending on the purpose. The classic line structure is dissolved. The star-shaped arrangement of many small segments with signal refreshment brings numerous advantages for stable operation and troubleshooting. These are known, among other things, from Ethernet-based networks.

Expert advice: We recommend the use of repeaters to separate conspicuous or interference-prone participants. The galvanic separation of the segments prevents effects on the complete PROFIBUS system.

Integrated quick diagnosis and error filtering

All repeaters of the MULTIrep series permanently monitor the PROFIBUS telegram traffic. The status LED on the device signals any occurring logical or physical anomalies. Error telegrams and telegram repetitions are also signaled by the bus LED. The data LED generally indicates whether the slaves on the channel are communicating and if there are any configuration errors. Therefore, the health status of the respective PROFIBUS segment can be permanently monitored and checked quickly.

The integrated diagnosis enables the maintenance technician to narrow down the error to the affected segment. The status LED makes this segment easily identifiable.

If error telegrams or signal interference occur in a segment with repeaters, errors are automatically filtered and not transferred to other segments, preventing interactions outside the affected segment.
