        • APPLICATIONS

          Where it may be used

          Use it only in the engineered PROFIBUS redundancy topology. Preserve line-A/line-B separation, shield continuity, segment termination and cable routing. Verify power and bus LEDs, both line paths, device communication and switchover behavior at the configured baud rate.

          Redundant PROFIBUS lines

          Maintains separate A and B communication paths in the documented topology.

          Single-device coupling

          Connects the verified non-redundant device or segment to the redundant pair.

          Termination control

          Keeps shielding and end-of-segment termination consistent with the network drawing.

          Bus-path failover

          Proves communication through each line and the expected switchover response.

      Features:

      • ABB article 3BSE091723R1 identifies RLM02, a redundancy link module used to connect a non-redundant PROFIBUS DP device or segment to redundant PROFIBUS lines.
      • Match article 3BSE091723R1, PROFIBUS line A/B assignments, baud rate, termination, 24 V supply, connector type and network addressing.
      • Verify power and bus LEDs, both line paths, device communication and switchover behavior at the configured baud rate.

      RLM02 3BSE091723R1 must be selected from the complete manufacturer identity and the receiving-system evidence. Use it only in the engineered PROFIBUS redundancy topology. Preserve line-A/line-B separation, shield continuity, segment termination and cable routing.

      Official source: ABB RLM02 product data sheet. Exact article and redundancy-link function; installed PROFIBUS design controls port and segment use.
      RLM02 3BSE091723R1 official technical documentation and related ABB resources.Important Notice: Confirm the complete article number and installed configuration before replacement. Each link opens in a new page.

      RLM02 bridges the documented non-redundant PROFIBUS side to redundant line A and line B.

      Keep cable, shield and termination assignments separate and consistent with the topology.

      Test each bus path and observe RLM02 status while the device remains in communication.

      Technical notes

      RLM02 3BSE091723R1 must be controlled by its complete identity. Exact article and redundancy-link function; installed PROFIBUS design controls port and segment use. Preserve line-A/line-B separation, shield continuity, segment termination and cable routing. Verify power and bus LEDs, both line paths, device communication and switchover behavior at the configured baud rate.

      PROFIBUS Path Selection

      RLM02 must preserve the engineered distinction between redundant PROFIBUS lines A and B and the non-redundant device side. Baud rate, connector orientation and segment termination must match the existing network.

      Bus Switchover Proof

      After installation, confirm normal status on both redundant ports, then use the approved maintenance test to demonstrate communication through each path independently. Record LEDs, diagnostics and recovery time.
