摘要:
The invention relates to a node device of a serial bus system, to a bus system with a node device of this type, and to an input/output card. In serial bus systems, in which individual node devices can have only a limited address space, and in which a number of input/output cards can be connected in order to control and/or regulate an item of external peripheral equipment, limitations arise for the individual input/output cards with regard to the available address space. Normally, the input/output cards, which are connected to the node device, are required to divide the address space of the node device among each other. In order to rectify this problem, the invention provides that a node device (1) of a serial bus system, which has slots (8, 8', 8'' to 8n) for input/output cards (4, 4', 4 ), is additionally equipped with a splitter (5) for duplicating a received bus signal and for injecting the duplicated bus signal into another data line (3), the additional data line serially connecting the node device (1) to input/output cards connected via the slots.

In a refrigerating/air-conditioning apparatus including operating/controlling units such as outdoor units, indoor units and control devices for individually or collectively controlling the driving of the outdoor units and the indoor units, each operating/controlling unit being equipped with a controller for controlling the driving of the operating/controlling unit, the controller having a rewritable memory for storing a control program, control parameter data, control data, etc., and the controllers being connected to one another through communication lines, there is provided at least one data writer which is connected to at least one of the operating/controlling units to transmit control communication data to the controllers of the operating/controlling units when the content of the memory of the controller of at least one of the operating/controlling units is required to be written/rewritten, wherein the control communication data contains identification information with which each controller judges whether the control communication data received is addressed to the operating/controlling unit of the controller concerned, and if the control communication data is judged to be addressed to the operating/controlling unit of the controller concerned, the controller writes/rewrites the control data, etc. of the memory thereof.
摘要:
A cell for use in a network which provides sensing, control and communications. Each cell, as part of its manufacturing process, includes a unique 48-bit identification number. A terminal on the cell enables the broadcast of this unique number onto the network during initialization of the network so that each cell can be identified. The input/output section of each cell communicates with the plurality of processors in the cell allowing one processor to interpret messages received from the network without interrupts of functions performed by other processors.

摘要:
A large number of irrigation system devices (26, 28) connected to a common two-wire cable (20) can be powered and individually controlled from a central location (14) by transmitting over the cable DC pulses of alternating polarity. Control information is conveyed by transmitting a command pulse train consisting of a series of pulses, separated by short no-power intervals, whose polarities indicate logic ones or zeros. Following a command pulse train, a selected watering station decoder (22) acknowledges receipt of instructions by drawing current during a predetermined pulse of an alternating-polarity power pulse cycle, while a sensor decoder (24) returns binary data by drawing current during one or the other of the alternating-polarity pulses of a series of power pulse cycles.
摘要:
Die Erfindung betrifft ein Steuerungssystem für eine Kunststoff verarbeitende Maschine mit mindestens einer zentralen Verarbeitungseinheit (10, 10') mit einem Realzeitbetriebssystem, wobei die zentrale Verarbeitungseinheit (10, 10') über ein Bussystem (16, 16') mit Aktoren und/oder Sensoren (S1, S2 ... Sn) verbunden ist und zumindest ein Aktor und/oder ein Sensor auf eine schnell veränderliche Größe mit hoher Auflösung gerichtet ist. Um die erste zentrale Verarbeitungseinrichtung von übermäßigen Steuerungs- oder Kommunikationsaufgaben zu entlasten wird vorgeschlagen (i) eine erste Vorverarbeitungseinheit zu verwenden, welche für mehrere Sensoren und/oder Aktoren die Signalvorverarbeitung etc. übernimmt oder eine weitere Vorverarbeitungseinheit vorzusehen, welche die zentrale Verarbeitungseinrichtung unmittelbar von der Buskommunikation entlastet.
摘要:
Automotive vehicle electronic devices are diagnosed through communication with a flexible diagnostic tool which automatically switches between a wide variety of communications protocols as required for diagnostic communication tasks presented to the tool. Simultaneous communication with a plurality of devices under a plurality of communications protocols is supported by the tool wherein communication hardware is available for parallel communications under the various protocols via various communication channels and is apportioned for each active diagnostic communication task for the duration of that task.
