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.
