Product  Details

The PROFIBUS Power Hub gateway is a system component of the FieldConnex ® PROFIBUS Power Hub (Segment Coupler 3 or SK3) and plugs into the gateway motherboard. The gateway operates with power supply modules connected to the same or a separate motherboard. This system component transparently couples PROFIBUS DP with up to 4 PROFIBUS PA segments.

Communication is transparent between DP and PA. The gateway of the Segment Coupler makes each PA device appear as if it was connected to DP: This relates to addressing, cyclic/acyclic data exchange, and the transfer rate. Segment design is clear and easy to understand without subnetworks. The gateway itself is confguration-free. All in all, these features significantly reduce engineering work.

The gateway provides a PA master for each segment and thus enables short bus cycle times.

In redundant configuration, 2 PROFIBUS gateway modules operate with handshake between each communication. During redundancy transfer, communication is seamless for DP master and field devices, ensuring continued plant operation. Internal status is reported via volt-free contact and via diagnostic telegram on PROFIBUS DP.
