摘要： For a bi-directional bus topology, a node connection includes two select line connections for a select line of a serial network. The select line is broken at the node connection. A bus direction module configures a first select line connection for an input line and a second select line connection for an output line in response to detecting a selection event. At least a portion of the bus direction module includes one or more of hardware and executable code, the executable code stored on a memory.

摘要： A system and method of determining orientation of a physical location on a cart or end effector located on the cart in an independent cart. system receives a feedback signal from a sensor on the cart, A multi-axis device may generate three or more signals corresponding to X, Y, and Z axes orientations. Processing may be performed on the signals to generate a value of yaw, pitch, or roll of the cart. The feedback or processed signals are transmitted from the mover to a remote device external from the track. The real-time orientation information may be used to implement closed-loop control of an actuator mounted on or external to each cart as the cart travels along the track, Power for the devices on the mover may be provided by a battery mounted on the cart or by a wireless power transfer system.

摘要： A communication module mounted to a motor provides for communication between a motor controller and a motor or between the motor controller and devices mounted on or proximate to the motor. The communication module may be configured to accept signals from various different encoders and/or load devices mounted on or proximate to the motor. The communication module receives a position feedback signal from a primary encoder interface and is configured to transmit the data to the motor controller at a periodic update rate. The communication module also receives feedback signals from at least one additional device and transmits the data to the motor controller. The communication module synchronizes its periodic update rate with the motor controller such that the position feedback signal may be utilized to control operation of the motor. The additional feedback signals may be communicated at the same or differing update rates.

摘要： Embodiments of this present disclosure may include a system that includes a first network device. The first network device may perform an operation according to a device configuration file. The system may also include a second network device that directly communicatively couples to the first network device through a peer-to-peer (P-P) communication network. The second network device may include a backup file of the device configuration file. The second network device may transmit the backup file of the device configuration file to the first network device in response to detecting that the first network device is lacking the device configuration file.

摘要： A system may include a first device that has a first network component and a second device that has a second network component. The second network component may receive a data packet from the first network component based at least in part on a network address, where the network address is generated based at least in part on a location of the first device.

摘要： An electronic device in an industrial control system may be connected as a network device, such as via EtherNet/IP. The device may be configured to provide an “unconnected” message notification (or “active report”) when the device detects an enumerated condition, such as an error or deviation. An unconnected message may be a message sent between two or more applications (which may be of the same or different devices) without pre-established communication channel bindings. An unconnected message may include routing path information for routing the message to the host computer, application path information for associating the applications, and data payload information related to at least one of a state of the electronic device and the enumerated condition.

摘要： An independent cart system includes an inductive link for contactless power transfer between a track and each mover as the mover travels along the track. A system for contactless data transmission between movers and a controller in the independent cart system includes a transmitter and/or receiver mounted on each mover and a complementary receiver and/or transmitter mounted on a track. The transmitter receives data to be transmitted across the inductive link and modulates a voltage present on either the primary or secondary winding to which it is coupled. The modulated voltage present on one winding induces a corresponding modulation on the voltage present on the other winding. A receiver operatively connected to the other side of the inductive link detects the modulated voltage and decodes the data from the modulated voltage received across the inductive link.

摘要： A system is provided in which a position for each device (relative to other devices) in a topology, and a corresponding device ID for each device, may be predetermined. Then, the predetermined position and corresponding device ID for each device may be compared to actual devices in a topology having preprogrammed device ID's and pre-assigned IP addresses. If the comparison produces a match, the pre-assigned IP addresses in the actual devices may be utilized. However, if the comparison does not produce a match, the condition may be reported for further action.
