International Classification:

G06F 19/00

US Classification:

700170, 700 1, 700 28, 709220, 709224

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.

US Classification:

709224000, 700028000

Abstract:

A motor control system includes a first peripheral device and a motor control host. The first peripheral device is operable to generate a first configuration message. The motor control host includes a plurality of ports and the first peripheral device is coupled to a first one of the ports. The motor control host is operable to store a configuration mask defining access rights for each of the ports, receive the first configuration message over the first port, and accept or reject the first configuration message based on the configuration access defined in the configuration mask for the first port.

International Classification:

G06F 1100

US Classification:

395181

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.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

G01C 412

US Classification:

222641

Abstract:

A beverage dispenser includes a body having a bore with an inlet, an outlet and a valve seat therebetween. A valve stem has a seal to selectively engage the valve seat to open and close the bore to a flow of beverage between the inlet and outlet. A serving lever is pivotally connected to the body and selectively coupled and decoupled to the valve stem by a clutch which is operated by a solenoid. Operating the serving lever may move the seal away from the valve seat only when clutch couples the serving lever to the valve stem. A control circuit operates the solenoid to cause the clutch to decouple the serving lever from the valve stem when the beverage has been dispensed continuously for greater than a defined period of time.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H02H 300

US Classification:

361 93000

Abstract:

Solenoid control circuitry can be used with either a first solenoid requiring a relatively large holding current or a second solenoid requiring a relatively small holding current. A solenoid connected with the solenoid control circuitry is initially energized to effect operation of the solenoid from an unactuated condition to an actuated condition. A detector detects whether a characteristic of the initial energization of the solenoid corresponds to a characteristic of the first solenoid or the second solenoid. The solenoid control circuitry varies the amount of holding current supplied to the solenoid as a function of whether the detector detects the first solenoid requiring the relatively large holding current or the second solenoid requiring a relatively small holding current. A fault detection circuit is provided to interrupt energization of the solenoid in the event of an excessive flow of current.

International Classification:

H02H 7/20
H02H 1/00
G05B 19/05

Abstract:

A method may include receiving, by respective processing circuitry of one or more power modules of an industrial automation device, a control signal from a controller of the industrial automation device. The power modules may include driver circuitry and a power converter that may provide power to a motor based on the signal. The method may also include, detecting, by the respective processing circuitry, a lack of communication from the controller based on the signal, and, in response to detecting the lack of communication from the controller, transmitting, by the respective processing circuitry, a first command to gating signal enable circuitry to disable the driver circuitry, and transmitting, by the respective processing circuitry, a second command to driver power circuitry to prevent power from being provided to the driver circuitry.

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.
