Functional Features

1. Redundancy Management:
   • Dual Path Conversion: Converts a single non-redundant PROFIBUS line into two redundant RS485 lines (A/B) or merges redundant lines into a single non-redundant path.
   • Automatic Line Switching: Instantaneously switches to the backup line (A/B) in case of primary link failure, minimizing downtime.
2. Network Monitoring:
   • Line Activity Tracking: Monitors all three lines (A, B, M) for data transmission and error states.
   • Diagnostic Feedback: Front-panel LEDs indicate power status, communication activity, and fault conditions.
   • Alarm Contact: Potential-free relay output for remote error signaling.
3. Flexible Deployment:
   • Positioning Options: Can be placed directly after the PROFIBUS master, before a segment with multiple slaves, or in front of critical single-slave devices.
   • Transparent Operation: No configuration changes required for connected PROFIBUS devices, ensuring compatibility with existing networks.
4. Scalability:
   • Station Capacity: Supports up to 31 PROFIBUS slaves per interface, expandable via repeaters and media converters.
   • Extended Line Length: Achieves longer bus distances through signal regeneration and repeater integration.

Application Scenarios
