Product Information

Product Description

Replacement product: ProfiHub B5+R

The ProfiHub B5+R is identical to the ProfiHub B5+RD including the feature of an integrated micro ProfiTrace diagnostic unit.


Authorized North America Distributor Stamp

The ProfiHub B5+RD is the first ProfiHub to provide a built-in PROFIBUS DP slave for transferring diagnostic data to a host system. Identical to the ProfiHub B5+R, this unit has the additional feature of an integrated micro ProfiTrace diagnostic unit.

Once the user provides the ProfiHub with a software bus address, the data can be configured using the GSD file. The cyclical data can contain simple statistics up to complex structures identifying channel problems.

Diagnostic Information:

  • Live List
  • Statistics
  • Power Status
  • Redundant Status
  • Termination Status

Because the ProfiHub B5+RD is based on the ProfiHub B5+R, it is an advanced, flexible and robust network component for PROFIBUS DP installations. It has the unique capability to implement long multi-device spur lines and backbone structures with star/tree segments in IP 20 applications.

Benefits Include:

  • Hot slave insertion and removal during operation
  • Short circuit protection on each Channel
  • Option to create a redundant path to other Hubs or ComBricks
  • Status and error display (per Channel)
  • Suitable for all DP cables
  • On-board DB9F connector on each Channel for maintenance activities
  • Cost Savings

Application Areas:

  • Dynamic spur lines to actuators, flow meters and pH analyzers
  • Removable drives and motors
  • Pull/Plug motor control centers (drawers)
  • Roof mounted devices in tank farms
  • Barrier for non-galvanic isolated equipment
  • Networks with requirement for High Availability/up-time
  • Large star/tree structured networks


  • Micro ProfiTrace Diagnostics
  • 5 Isolated Channels
  • 31 Devices per channel
  • DP - RS 485 specifications for each channel
  • Each channel has status and error display
  • Each channel has short circuit protection
  • Max 1200 m spur line length (depends on baudrate)
  • Configurable grounding system
  • Integrated termination facilities
  • Bus redundancy option in Hub mode
  • IP 20 classification

DP Slave Features

  • DP-V0 (certification number: Z01885
  • Ident Number: 6970
  • Software Addressing (0-126)
  • 32 Bytes diagnostic data
  • Maximum 85 bytes input / Maximum 5 bytes output (90 bytes total)
