Title: A SWITCH DEVICE FOR AN AUTOMATION NETWORK
Abstract:
A switch device (l) for connecting a plurality of field devices (2a - 2p) to one single master port (4) of a master device (3), the master device (3) providing a gateway between the plurality of field devices (2a - 2p) and an upper level network (10) and being configured to control a communication between the upper level network (10) and the plurality of field devices (2a - 2p), the switch device (l) comprising: a physical master-side port (5) for connecting the switch device (l) to the single master port (4) and for establishing a master communication channel (MCC) between the master device (3) and the switch device (l); and a plurality of physical field device-side ports (6a - 6d) for connecting the switch device (l) to the plurality of field devices (2a - 2p) and for establishing a plurality of field device communication channels (FCC) between the respective field devices (2a - 2p) and the switch device (1); wherein the switch device (l) is configured to transfer data between the master device (3) and the plurality of field devices (2a - 2p) through the master communication channel (MCC) and the plurality of field device communication channels (SCC) using a single communication protocol for an automation network.
