The Anybus X-gateway family with Profinet-IRT functionality and with integrated 2-port switch technology from HMS, enables easy integration of existing Profibus, Interbus or CANopen fieldbus networks into new Profinet based network segments. The gateways provide a transparent link for up to 240 bytes of I/O signals between the two networks. They can be integrated directly into line topology based installations eliminating the need for external switches. Configuration is done within a few minutes and no programming or specific PC hard- or software is required.
