Abstract: Exemplified methods and systems are disclosed that facilitate field devices controlled by networks using Power-over-Ethernet. The field device includes a field-side circuit having a plurality of universal and independent configurable (and re-configurable) input-output interface that can universally interface to most industrial field devices. Each channel employs a group of analog-to-digital (A/D) conversion and digital-to-analog (D/A) conversion paths that facilitate independent data flows in which signals are not multiplexed across individual interfaces. In addition, the field-side circuit operatively couples to a control side circuit with two Power-over-Ethernet modules, e.g., for redundancy, that each facilitates communication and power to the field-side circuit while, concurrently, reducing wiring complexity for a redundant system during installation.

Abstract: A control module comprising a display, according to various embodiments, can include an input/output module configured to receive one or more signals responsive to a state of at least one diagnostic sensor, the state being indicative of at least one from the group including a fault, an error, and a malfunction. A processor is configured to match values of the received signals to one of a plurality of stored table values to identify a matching value, each matching value corresponding to a code. A barcode generator creates a two-dimensional barcode representative of the code and outputs the barcode to the display. In one embodiment, the diagnostic sensor can be an internal diagnostic sensor within the control module capable of performing self-diagnostics. In another embodiment, the diagnostic sensor can be an external diagnostic sensor associated with an external device for performing remote diagnostics.
