ProfiHub B5+RD

ProfiHub B5+RD – PROFIBUS Hub with Diagnostic slave device

ProfiHub B5+RDThe ProfiHub B5+RD is a member of the famous ProfiHub family and identical as the regular ProfiHub B5 with an additional integrated micro ProfiTrace diagnostic unit. The ProfiHub offers a PROFIBUS DP slave device to transfer bus statistics and device event information to the PLC/DCS system.

This innovative network component is an essential element when it comes down to maintaining PROFIBUS DP systems when the host system has to be involved. The application software was in past never able to identify bus diagnostic information and act accordingly. With the ProfiHub B5+RD this information is fully available. Even the location of certain devices behind the channels of the ProfiHub is very useful to identify the topology from a host system point of view.

The user has to provide the ProfiHub with a software bus address (set slave address function). By means of the GSD file the user can configure the data that is required from the ProfiHub. The cyclical data can contain simple statistics up to complex structures identifying channel problems.

ProfiHub B5 RD 0230The ProfiHub B5 is a solid network component providing reliable solutions for spur lines and star-shaped structures in PROFIBUS DP networks. Furthermore, it’s the first ProfiHub that has been provided with a built-in PROFIBUS DP slave for transferring diagnostic data to a host system.
