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.

Rapid file authentication on automation devices

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.

Extensible device object model

A motor drive comprises a power sub-assembly and a control sub-assembly removably secured to the power sub-assembly. The power sub-assembly contains all power electronic circuitry and driver circuitry for the power electronics. The control sub-assembly comprises control circuitry for implementing a motor control routine that generates control signals for the power sub-assembly. The control sub-assembly is configured to conform to a USB mass storage device class such that it will appear as an icon on a configuration station when coupled to the configuration station via a USB cable. Thereafter, the drive may be accessed by selecting the icon, and parameter file and data transfer may be performed, such as by drag-and-drop transfer steps.

Motor drive configuration system and method

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.

Method and apparatus for disabling ports in a motor control system

A wireless user interface is operable to interface with an industrial control system including a device operable to store a first password and a wireless interface module operable to store a second password. The wireless user interface includes a processing unit operable to prompt a user for the first and second passwords, connect to the wireless interface module using the second password, and establish a first connection through the wireless interface module to access the device using the second password.

Security layers for wireless industrial control user interface

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.
