  • Patent number: 10970369
    Abstract: An industrial device is configured to implement a lightweight file authentication sequence that rapidly verifies the integrity of mobile code supplied to the industrial device. The industrial device generates a file authentication code (FAC), which is stored on the industrial device and only made accessible to users via a local connection to the industrial device. The device-specific file FAC is installed on the program development application used to develop or edit the mobile code to be executed on the industrial device. The development application provides the mobile code to the industrial device together with a hash-based message authentication code (HMAC) generated using a retrieved copy of the FAC. The industrial device only permits execution of the mobile code if the HMAC included with the mobile code matches a locally created HMAC generated by the industrial device based on the mobile code and the device's local copy of the FAC.

  • Patent number: 9823907
    Abstract: Systems and/or methods are provided relating to an extensible framework. The extensible framework provides constructs with which device developers can model devices within the framework to enable a host application utilizing the framework to interact with the devices. New devices can be supported by the framework without disrupting existing devices or the host application.

  • Patent number: 8355821
    Abstract: A motor control host includes a plurality of ports, a memory, and a processing device. The memory is operable to store an enable mask defining an enablement state for each of the ports. The processing device is operable to send a first message over those selected ports having an affirmative enablement state to maintain a communication link over the selected ports and inhibit the first message for those ports having a negative enablement state. A method for configuring a motor control system including a motor control host having a plurality of ports includes storing an enable mask defining an enablement state for each of the ports. A first message is sent over those selected ports having an affirmative enablement state to maintain a communication link over the selected ports. The first message is inhibited for those ports having a negative enablement state.

  • Patent number: 5832195
    Abstract: A method and apparatus to be used with a peer-to-peer network including a plurality of separate controllers which can control each other, the method and apparatus to be used to determine when a fault conditions occurs when one controller which has controlled a different controller is rendered incapable of network communication. In the present invention, each individual controller includes a control list which tracks all of the other controllers that have controlled the individual controller. When one of the controllers on a control list is rendered incapable of communicating with the individual controller, the controller that is incapable of communicating is cleared from the control list associated with the individual controller and the tools associated with the individual controller are forced into safe fault operation until controlled by an other controller.
