Abstract:
The invention relates to a control system for a subsea installation based on CAN bus technology. A single cable forms a backbone for transmitting signals and/or power from a central control unit to a number of devices or sensors on the installation. Terminals are attached to the cable at intervals, allowing devices to be plugged in while the system is operable. A termination may also include repeaters or amplifiers for transmitting signals over longer distances.
Abstract:
Bei einem Verfahren zum Steuern eines Fadenverarbeitungssystems (S) wird ein Signal eines eine Fadenbewegung und/oder einen Fadenbruch überwachenden Sensors (6, 17) im Hinblick auf Relevanz für eine System-Abschaltungsund/oder SystemKorrekturmassnahme in einer von einer Hauptsteuereinheit (CU) einer Textilmaschine (M) separierten Substeuereinheit (CU s ) ausgewertet und nur ein als relevant ausgewertetes Signal (i R1 ) an die Hauptsteuereinheit (CU) übertragen. Im Fadenverarbeitungssystem (S) kommuniziert eine eine Signalauswerteschaltung (EV) aufweisende Substeuereinheit (CU s ) mit dem Sensor (6, 17) und mit der Hauptsteuereinheit (CU), und ist für die Substeuereinheit ein Übermittler von Informationen jeweils zur Relevanz der Signale hinsichtlich einer Systemabschaltungs- und/oder Systemkorrekturmaßnahme vorgesehen.
Abstract:
The invention relates to a method for allocating a unique ID to a node in a network making a request to that effect, wherein the requesting node generates an ID and sends an ID request comprising the ID over the network, wherein each node in the network that already possesses said generated ID will send an ID ban comprising the generated ID over the network in response to detection of said ID request. The invention furthermore relates to a method for communication between objects in a network, in particular sensors, actuators and/or control objects, wherein a sending object sends a message intended for one or more receiving objects by making use of data output means, wherein at least substantially every receiving object in the network possesses a set of address fields which may comprise a non-unique address value, wherein the message is addressed by the sending object by prescribing one or more address values for one or more address fields, and wherein the message will be input by data input means of the receiving object if all the stated address values in the corresponding address fields of the object comply with the prescribed address values in the message. The invention furthermore relates to a method for controlling objects in a network, in particular sensors, actuators and/or control objects, wherein a controlling object sends a message comprising data on its characteristic variables over the network via data output means without being requested to do so.

Abstract:
The present invention relates to an arrangement for controlling a plurality of controllable devices (55a, 55b) connected to at least one common bus (24). The arrangement comprises at least one input member (21) and at least one output member (22) interconnected through said common bus (24), each input and output member having at least one input terminal (35) and at least one output terminal (45), respectively. Each input/output terminal has a unique identity, said input member (21) being arranged to receive a control signal from at least one control arrangement (51a-51c) connected to said at least one input terminal (35) of said input member. The control signal generates an action signal comprising an address corresponding to a unique identity of an output terminal of said output member (22) connected to at least one of said controllable devices (55a, 55b). The action signal is provided on said common bus by said input member to be received by said output member.
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.
Abstract:
A glassware forming machine system (10) includes a glassware forming machine (24) having first operating mechanisms for converting gobs of molten glass into articles of glassware, a gob delivery system (12 to 22) having second operating mechanisms for delivering gobs of molten glass to the glassware forming machine, a ware handling system (26 to 32) having third operating mechanisms for receiving and conveying articles of glassware from the glassware forming machine, and an electronic control system (34 or 120) for controlling and coordinating operation of the first, second and third operating mechanisms. The electronic control system includes a machine controller (37 or 37a) coupled to the first operating mechanisms of the glassware forming machine for controlling and coordinating operation of the first operating mechanisms to produce articles of glassware. A gob delivery controller (58 or 78a, 80a, 82a, 84a) is coupled to the second operating mechanisms of the gob delivery system for controlling and coordinating operation of the second operating mechanisms to deliver gobs of molten glass to the glassware forming machine. A ware handling controller (56 or 56a, 62a) is coupled to the third operating mechanisms of the ware handling system for controlling and coordinating operation of the third mechanisms to convey articles of glassware from the glassware forming machine. A serial data bus (54) interconnects the machine controller, the gob delivery controller and the ware handling controller for communication with each other to coordinate with each other operation of the first, second and third operating mechanisms.
Abstract:
Es wird ein einheitliches und modular erweiterbares System zum weitestgehend rückwirkungsfreien und zeitsynchronen Mes-sen und Analysieren von weit verteilten Signalen von aus meh-reren Teilprozessen (T1 ... T2) bestehenden industriellen Prozessen vorgeschlagen. Mittels Messköpfen (M1 ... M7) wer-den beliebige in den Teilprozessen (T1 ...T2) vorliegende Signale erfasst und gegebenenfalls mit einem Zeitstempel ver-sehen in einer vorgegebenen Form als Mess- oder Zeitsignale an ein Messbussystem (B1 ... B2) weitergegeben, wobei das Messbussystem (B1 ... B2) nicht identisch mit vorhandenen, der Automatisierung dienenden Bussystemen (P1 ... P2) ist. Die Mess- und/oder Zeitsignale werden von Datenkonzentratoren (D1 ... D2) weiterverarbeitet. Lokale oder vom industriellen Prozess beliebig entfernt vorgesehene Auswerteeinheiten (E1 ... E2) und/oder Anzeigeeinheiten (A1... A2) ermöglichen die weitere Verarbeitung beziehungsweise Visualisierung von Mess- und/oder Zeitsignalen. Es sind Messköpfe vorgesehen, die ein standardisiertes Zeitsignal wie das des Global Positioning Systems (GPS) erfassen können.
