  • Publication number: 20140226460
    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.

  • Patent number: 8769158
    Abstract: A modular, high-availability network for an industrial control system employs a plurality of base modules having backplane and using network ring topology. Base modules may include I/O base modules for communicating with industrial processes or machines, an adapter base module for communicating with a programmable logic controller (PLC) and/or a bus expansion base module for providing additional I/O base modules. Base modules may be arranged side-by-side, having a backplane in a bank. Another embodiment may include having plurality of banks. The network ring topology used by the base modules is normally opened by a ring supervisor at the ring supervisor location. Upon failure of the network, the ring supervisor reconnects the ring to provide an alternative transmission path around the failure point.

  • Patent number: 8628004
    Abstract: Systems and methods for utilizing electronic keying features stored within one of the components (e.g., I/O modules, terminal blocks, bases) of I/O devices may include reading or detecting the electronic keying features using electronic key identification circuitry in one of the other components of the I/O devices. More specifically, the electronic keying features may include unique identification keys that may be read or detected by the electronic key identification circuitry to determine whether the components (e.g., a paired I/O module and terminal block) are associated with each other and intended to operate together. For example, the electronic key feature may be disposed within a terminal block and the electronic key identification circuitry may be disposed within an I/O module, or vice versa. In addition, the electronic key feature and/or the electronic key identification circuitry may be removable from their respective component of the I/O device.

  • Patent number: 8246358
    Abstract: A contact device enables a contact method for RIUP operations relative to a backplane. The contact device includes first and second contact portions, each including first and second spaced-apart contact arms. The first and second contact portions are located relative to each other on the backplane such that when the contact device is in a first operative condition, the respective first contact arms abut each other and define a first electrical conduction path and the second contact arms are spaced from each other.

  • Publication number: 20120047288
    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.

  • Publication number: 20120044082
    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.

  • Publication number: 20120043830
    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.
