Abstract: A monolithic integrated circuit that supports multiple industrial Ethernet protocols, fieldbus protocols, and industrial application processing, thereby providing a single hardware platform that may be used to build various automation devices/equipment implemented in an industrial network, such as controllers, field devices, network communication nodes, etc.

Abstract: A control device having an integrated switch and being configured to logically enable and disable an Ethernet port of the integrated switch. Further disclosed is a device network consisting of at least two field devices, a primary control device and a primary switch, a secondary control device and a secondary switch, which are connected in a daisy chain loop topology. And wherein the secondary control device is configured to logically enable and disable an Ethernet port of the secondary switch. Further disclosed is a flat network consisting of such a device network. Further disclosed is a method for controlling a redundant connection in a flat network, consisting of detecting failure of the primary control device, initiating failover, enabling the Ethernet port of the secondary switch, and disabling the Ethernet port of the primary switch.
