  • Patent number: 10154603
    Abstract: Present embodiments include an automation control system that includes an input/output device module with a device bus therein. The input/output module also includes a first bus contact on a first side of the input/output device module and communicatively coupled with a first end of the device bus, and a second bus contact on a second side of the input/output device module and communicatively coupled with a second end of the device bus. The second side generally faces an opposite direction from the first side and the input/output device module is configured to be coupled with additional input/output device modules positioned on the first and second sides of the input/output device module via the first and second bus contacts.

  • Patent number: 10028404
    Abstract: Present embodiments include an adaptable automation control component that includes a base capable of communicatively coupling with a system bus and with a functional module that includes communication and control circuitry. The adaptable automation control component also includes a device power bus including electrical contacts that are capable of communicatively coupling the adaptable automation control component with a separate automation control component, and an activation mechanism including circuitry capable of continuing the device power bus when the activation mechanism is engaged, and capable of discontinuing the device power bus when the activation mechanism is disengaged. The adaptable automation control component facilitates functionality of the adaptable automation control component as an input/output module or a power distribution module depending on whether the activation mechanism is engaged or disengaged.

  • Patent number: 9483928
    Abstract: Systems and methods are provided for aligning status indicators on a terminal block of an I/O device by locating the status indicators directly adjacent to or integrated directly within their respective terminals on the terminal block. The status indicators are illuminated by LEDs or other light emitters disposed within a housing of the I/O device. Light from the LEDs are directed to the status indicators by light pipes disposed within the housing of the I/O device. LED activation circuitry disposed within the housing determines a manner in which to activate the LEDs to illuminate the status indicators based on inputs and outputs between the I/O device and a controlled process. In certain embodiments, the status indicators are disposed on a raised section of the I/O device, which may be part of a removable LED indication assembly including the LEDs, light pipes, and LED activation circuitry.

  • Patent number: 9411614
    Abstract: Systems and methods provide re-configurable functionality within components of I/O devices without the need of disconnecting the components from each other. For example, in certain embodiments, when certain types of components are connected to each other, certain functionality sets within the components may be activated to provide combined functionality sets between the components. The combined functionality sets may, for example, be preferred functionality sets to be used when the particular types of components are connected to each other. Furthermore, in certain embodiments, functionality activation keys may be physically inserted into (or electronically communicated to) the components of the I/O device to activate certain functionality sets within the component into which the functionality activation key is inserted (or electronically communicated to), as well as within the other components of the I/O device to which the component is connected.

  • Patent number: 9338919
    Abstract: Base modules are provided over a backplane network for high availability control of industrial processes or machines. The base modules may include, for example, an I/O base module, which may control the industrial processes or machines and which may releasably receive an I/O function card, an adapter base module, which may communicate with an industrial controller over a separate control network, and a bus expansion base module, which may provide coupling to another bank of base modules. The base modules may be arranged side-by-side via electrical and mechanical connections. Logic of the I/O base module may detect the presence or absence of the I/O function card to allow coupling or bypassing of the I/O function card with respect to the backplane network.
