    摘要: Die Erfindung betrifft eine Bus-Konfiguration für einen UMS-Bus (universeller Melde- und Steuer-Bus), bestehend aus einem Netzwerk mehrerer UMS-Inseln (1), welche ihrerseits mindestens eine UMS-Einheit (2, 3) zum Einlesen von Meldedaten bzw. zum Auslesen von Steuerdaten und zum Verbinden von UMS-Inseln (1) umfassen. Um eine große Anzahl, dezentral anstehender Meldungen an eine Verarbeitungseinheit zu führen und Steuerkommandos auszugeben, wobei Erweiterungen hinsichtlich er Meldungen und Steuerkommandos problemlos projektierbar sein sollen, ist vorgesehen, dass die UMS-Einheit (2, 3) einen Einchiprechner (4) aufweist, wobei die UMS-Einheit (2, 3) einer UMS-Insel (1) über erste serielle Schnittstellen und die UMS-Inseln (1) über zweite serielle Schnittstellen des Einchiprechners (4) vernetzt sind.

    摘要: A system for connecting sensors to a control/monitoring system uses concentrators to time-division multiplex groups of sensors onto a bus. The sensors are connected to the concentrator by cord sets. A controller recovers the individual sensor data and supplies the same to the control/monitoring system. The sensors provide "on" and "off" impedances that differ from the "short" and "open" impedance of a cord set. Depending on the voltage the concentrator measures, the concentrator determines if a sensor is on or off, or a cord set is damaged or unconnected. The status of the cord sets is also provided to the controller.

    摘要: A sensor connection apparatus for connecting a plurality of sensors to a process controller having a bus for transferring information, wherein each sensor produces an output corresponding to a sensed condition, includes a respective sensor cable that can be connected at one end to each sensor; a concentrator having means for connecting each of the sensor cables thereto; and means for connecting the concentrator to the bus; the concentrator comprising circuit means producing for each sensor and associated sensor cable connected thereto a first signal in response to the sensor output and a second signal that corresponds to a sensor cable condition; the circuit means further operating to couple the first and second signals for each sensor connected to the concentrator onto the bus for access by the process controller. In one embodiment, the concentrator transmits data to the process controller using a standardized communications protocol, such as CAN, using a microcontroller and transceiver.
