Abstract:
The exemplified methods and systems support shared output drivers or shared control setting drivers across separate control devices for a redundant system of 1, 2, 3, or more control devices in simplex, dual, triple redundancy, and etc. Digital communication links between the control devices are implemented to facilitate sensing, from other control devices, of operation states (e.g., amount of contribution by the control devices to the shared output) and on-line/health status of other control devices in the redundant network.
Abstract:
A system includes a triple modular redundant (TMR) control system comprising three controllers. Each controller of the three controllers includes a current driver system configured to detect and regulate a portion of a total current output of the TMR control system, and a universal input-output (UIO) system comprising a plurality of universal input-output (UIO) ports, wherein the universal input-output (UIO) system is configured to detect the portion of the total current output and the total current output of the TMR control system via one or more of the plurality of the UIO ports, compare the portion of the current output and the total current output of the TMR control system, and adjust the portion of the total current output according to a predetermined total current output threshold.
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:
Systems for communicating over a communication interface are provided. An integrated circuit includes circuitry for monitoring a current flowing between two terminals of the integrated circuit. The integrated circuit also includes a voltage driver circuit for modulating a voltage between two terminals of the integrated circuit. The voltage driver modulates the voltage across the two terminals of the integrated circuit to encode data according to the Highway Addressable Remote Transducer protocol.
Abstract:
Described are systems, methods and computer-program product for replacing a prior input/output (I/O) module and terminal board with a universal I/O device by providing software based instructions and configuration settings for the installer. The method includes provisions for new wiring changes or harnesses as well as preset adapters, converting prior device configuration settings from an I/O module, pack, and/or terminal board to new configuration settings for a programmable I/O device, generating a wiring chart for any wiring changes based on the settings, and displaying the information for the installer and/or programmer's use. This allows a universal I/O device capable of each channel having different operating modes to replace one or more of a mixture of several types of dedicated I/O modules. The installation documentation and configurations are automatically generated, reducing the chance of errors due to misinterpretation of multiple product documents while allowing the automatic transfer of product settings.

Abstract:
The present technology provides for an IO module system (e.g., an industrial control system) that can provide multiple-channel analog and digital interfaces to a number of sensor devices of different types, where each channel of the IO module is programmably configurable as a digital input, a digital output, an analog input, and an analog output. Each sensor interface is implemented on an individual channel basis using discrete components in communication with a microcontroller. The present technology enables the rapid implementation of an IO channel operable in a wide range of voltage and current modes needed for common sensor interfaces.

Abstract:
A document access control system includes a location-based document reader designed to provide a reading service, a location-based physical storage located in a first location and designed to store a physical document, and a location-based document server. The location-based document server stores an electronic document and delivers the electronic document to the location-based document reader. The location-based document reader derives a second location, and provides access to the electronic document based on the first and the second locations.
