NETWORK CONFIGURABLE INDUSTRIAL DEVICE

摘要

A device is configured to be operable in a plurality of network environments. A number of different configurations are available to be set on the device, where a first configuration enables operation on a first network, and a second configuration enables operation on a second, disparate, network. A plurality of external ports in conjunction with a multiplexer switch, network switch, internal CPU, external CPU, routing links, etc., can be combined to facilitate multiple configurations for the device. The device is suitable for incorporation into a human machine interface, for application in an industrial processing operation. Receive port information can be incorporated into a data frame to facilitate identification of an external port associated with the reception of the data frame. Applicable networks include linear topology, ring topology, star topology, Ethernet, ROCKWELL NEO, EtherNet/IP, one or more LANs, etc. Configuration can be via a USB device or an interface.

1. A network switching system comprising:
a switch comprising a central processor unit (CPU) side channel, a first input channel and a second input channel; an internal CPU connected to the CPU side channel of the switch and a computer bus; a first external port connected to the first input channel of the switch; a multiplexer (MUX) comprising at least two MUX switches, wherein a first MUX switch is connected to the second input channel of the switch; a second external port connected to the multiplexer; and a configuration parameter configured to select routing of the second external port to the first MUX switch in the multiplexer or a second MUX switch in the multiplexer.
