Two or more modules communicate over a common control network including receiving by a message packet having data defined by a signal level at defined bit quanta of a bit, the defined bit quanta being less than every bit quanta of a bit, and the communication device samples bit quanta other than the defined bit quanta. The module receives signal disturbances and decodes the signal disturbances as having a value different from an expected value of the certain bit. In another form, the module uses a first counter based on a clock local to the communication device and a second counter having a higher sampling rate than the first counter. Here, the module receives over the control network a synchronizing portion of a message and counts clock ticks of the second counter over a portion of the message to determine a clock rate for a module that transmitted the message.

High speed embedded protocol for distributed control system

A system, apparatus and method for efficient utilization of available band-width on the system's bus connection. The system includes a scheduler configured to receive a virtual schedule that provides at least one slot for sending a message over the communication bus. A module is configured to send a message over the communication bus.

Time and event based message transmission

A control network communication arrangement includes a second protocol embedded into a first protocol in a way that modules supporting the second protocol may be aware of and utilize the first protocol whereas modules supporting only the first protocol may not be aware of the second protocol. Operation of modules using the second protocol does not disturb operation of the modules not configured to use or understand the second protocol. By one approach, the messages sent using the second protocol will be seen as messages sent using the first protocol but not having a message necessary to understand or as needing a particular response. In another approach, modules using the second protocol can be configured to send message during transmission of first protocol messages by other modules, the second protocol messages being triggered off of expected aspects of the message sent under the first protocol.

Operation of modules using the second protocol does not disturb operation of the modules not configured to use or understand the second protocol. By one approach, unique additional information is embedded into an end of frame portion of a message to confirm that the portion is the end of frame portion. This acts as a quality check confirming proper synchronization and decoding of the signaling on the communication bus.

Confirming data accuracy in a distributed control system

A control network communication arrangement includes a second protocol embedded into a first protocol in a way that modules supporting the second protocol may be aware of and utilize the first protocol whereas modules supporting only the first protocol may not be aware of the second protocol. Operation of modules using the second protocol does not disturb operation of the modules not configured to use or understand the second protocol. By one approach, unique additional information is embedded into a message to provide authentication of the first protocol message. This acts as a quality check protecting against unauthorized messaged being sent on the control network.

The invention relates to a remote control system () comprising mobile units (), and a by control means () provided controller unit for these. Said units are equipped with a function performing means () and transferring means () that generates information signals () respectively transmits the same. Signal processing means () and their exerting function () for controlling the functions of the respective mobile unit are placed respectively takes place only in the current mobile device. In accordance with the proposed use in connection with the present invention object, a controller area network type of system is constructed with a distributed and integrated network structure (). Only signal processing means () and their function exertion means () for controlling of a mobile unit, which is positioned in the actual unit, is used for its control. According to the method establishes a structure of a controller area network type with modular units ('), nodes () and a communication protocol () for the node communication. All messages transmitted by the nodes are received by the modular units (). A information comparison () is used to select respective message or part thereof.

High speed embedded protocol for distributed control systems

Methods, systems, and apparatus for remotely piloting a vehicle. In one aspect, a system includes a transmitter capable to receive vehicle control signals and transmit the vehicle control signals to a vehicle including at least one receiver; one or more modules; and at least one power supply; wherein the at least one receiver receives the transmitted vehicle control signals and transmits the vehicle control signals in a CAN message format to all of the one or more modules; and each of the one or more modules selectively chooses which of the vehicle control signals in a CAN message format the module will respond to.
