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. The monolithic integrated circuit may comprise at least one application processor core operable to execute an industrial application and Ethernet connectivity/management code, including standard Ethernet connectivity/management code and industrial Ethernet connectivity/management code; a real time processing module configured to support a plurality of industrial Ethernet data link layers; an interface configured to be coupled to an external non volatile memory from which the at least one application processor is configured for execute in place processing; and on-chip RAM having a capacity sufficient to eliminate the need for external RAM in execution by the at least one application processor core of an operating system, the industrial application, and the Ethernet connectivity/management code.

Universal ethernet solution

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.

Control device and method for controlling a redundant connection in a flat network

A monolithic integrated circuit that supports multiple industrial Ethernet protocols, fieldbus protocols, and industrial application processing, providing a single hardware platform usable to build different automation devices/equipment implemented in an industrial network, such as controllers, field devices, network communication nodes, etc. The monolithic integrated circuit includes: one application processor core operable to execute an industrial application and Ethernet connectivity/management code, including standard Ethernet connectivity/management code and industrial Ethernet connectivity/management code; a real time processor configured to support a plurality of industrial Ethernet data link layers; an interface configured to be coupled to an external non volatile memory from which the at least one application processor is configured for execute in place processing; and an on-chip RAM having a capacity sufficient to eliminate the need for external RAM in execution by the at least one application processor core of an operating system, the industrial application, and the Ethernet connectivity/management code.

A device for controlling point-to-point communication between a module and a transmission bus, the device including a printed circuit that carries the transmission bus and that includes a connection element to connect the module to the transmission bus. The printed circuit includes a communication control unit disposed between the transmission bus and the connection element, the communication control unit includes unidirectional communication logic gates, and a logic control circuit for the logic gates. Such a device may, as an example, find application to programmable controllers.
