  • Patent number: 6985724
    Abstract: In a distributed control system for one or more machines and/or one or more processes, data and control commands are transmitted via radio connections between nodes in the control system. The nodes operate with radio transmitters and radio receivers and comprise or are controlled by activation devices for activating their transmission and receiver functions. The nodes also operate with time-determination devices which comprise or control the abovementioned activation devices. The time-determination devices are arranged to determine the transmission or reception position of the nodes by means of the activation devices and allocated settings or controls. The abovementioned settings or controls can be determined by means of one or more schedules implemented in or for the control system, in which the nodes are given unique or co-ordinated transmission and reception times on the radio connections.

  • Patent number: 5446846
    Abstract: A distributed computer system of interconnected module units which perform logical operations at different locations. A serial data bus interconnects all of the module units through a connecting device which enables the module to communicate over the serial bus. The connecting device includes a memory device having stored therein identification information to identify the module unit to other module units communicating over the bus. A logic circuit which is connected to the memory device transfers the information from the memory to the module unit during an initialization phase of the system. The module units are thereafter able to communicate over the serial data bus. The connecting device has first and second sets of connectors for mating with corresponding connectors on the serial bus and module units. Thus, each module need not know where it is being connected along the serial bus, as all information for communicating over the bus is provided by the connecting device.

  • Patent number: 5392421
    Abstract: In an arrangement for synchronizing data and other information in a computerized system which comprises a common serial data communication channel (212), two or several collaborating units (201) are arranged connectable to the channel, wherein a respective unit comprises a clock (207). A main clock is included in the system and the clock in one of the units can be used as main clock. The units with associated communication element and communication channel are arranged in such a manner that the time of the main clock can be transferred to the clocks of the other units. The clocks are arranged so that they can operate with a common time base. The units/communication elements comprise hard- and software or hardware which brings about the setting of a respective clock with predetermined accuracy in dependence on the main clock time.

  • Patent number: 5383116
    Abstract: An apparatus or manufacturing system in which a first member executes a desired function or action which is controllable as a function of at least one parameter characteristic for a second member is provided. A first detector detects signals corresponding to values of the at least one parameter of the second member. At least one transmitter receives the detected signals and assigns coded/numbered messages for each value of the parameter. The apparatus further includes at least one receiver with a control module for controlling the desired action of the first member. The signal transmission between the transmitter and the receiver occurs over a connection bus and the signals are transmitted in the form of the coded/numbered messages in a predetermined order, with well defined transmission times between the first detector and the transmitter and between the transmitter and the receiver.

  • Patent number: 5371859
    Abstract: A system provides data communications between measurement data generating/receiving modules connected to a common communication bus. A master station connected to the communication bus can assign access priority to various message data structures generated by each of the modules connected to the communications bus. As modules are added or subtracted from the total system, the master station can reassign priorities to each of the message data structures generated by the modules. In this way, bus traffic can be efficiently controlled with the ability to dynamically change priority of message data structures which are sent over the bus by the various modules. A transmission delay time is also assigned to each of the message data structures which requires that a time out period following the last data message to be sent over the bus be observed before transmitting the new message data structure. The different delays VT are related to the particular priority of a message data structure.
