PROFIBUS hub with a diagnostic functionality

08 July 2014

PROCENTEC has launched the ProfiHub B5+RD  which is believed to be the first ProfiHub that comes with a built-in PROFIBUS DP slave to forward diagnostic data to a PLC. 

This function allows the ProfiHub B5+RD to optimally monitor PROFIBUS DP installations and allows technical engineers to effectively detect PROFIBUS disruptions and find solutions more promptly. 

The ProfiHub B5+RD is a member of the existing ProfiHub family and provides a solution for spur lines and star-shaped structures in PROFIBUS DP networks. 

The ProfiHub B5+RD is the first ProfiHub that has been provided with a built-in PROFIBUS DP slave for transferring diagnostic data to a PLC. This network component is important when it comes to maintaining the PROFIBUS DP systems. Technical engineers can now access detailed diagnostic information about communication failures and current details of retries. Diagnostic information about redundancy of the PROFIBUS channels and supply status can be identified. In addition, the hub generates a live list of all PROFIBUS devices connected. When configuring an alarm contact, technical engineers are warned immediately in case of disruptions inside the PROFIBUS DP installations. 

The ProfiHub B5+RD features five galvanically separated transparent channels. Up to 31 devices can be connected to each channel, bridging a 1,200m distance. Each channel comes with dropout protection.
