摘要:
The invention proposes that a various quantity of logic slaves be realized in a field device for use in an AS interface network as a function of the assigned address, said logic slaves being addressable with the assigned address in the standard or extended addressing mode. It is thus possible for slaves to be provided in a field device with different profiles, by way of which different data types may be exchanged. The invention further proposes a method by means of which a field device having various slaves may be addressed in a simple manner so as to prevent double addresses. The number of logic slaves represents individual participants in an additional subordinate bus system.

A method and system for managing household devices is provided. The method includes: locating by multiple household devices the current position coordinates of a mobile terminal; computing by the multiple household devices their respective distances to the mobile terminal using the current position coordinates of the mobile terminal to obtain multiple pieces of distance information, and transmitting the distance information to a control center; selecting by the mobile terminal the smallest distance based on the distance information, and transmitting feedback information to the household device at the smallest distance; and receiving by the household device the feedback information and thus performing operations of turning on, turning off, or regulating. The present disclosure makes possible an intelligent and humane home management mode without addition of extra chips which thus results in low cost.
摘要:
The invention relates to an arrangement with several plug points (SP0 ... SP15) interconnected via a system bus (SYB) with data and control lines and via address lines (AL0 ... AL15), into which the functional units (FE0 ... FE15) can be plugged. Every function unit which is suitable for read and/or write access (CPU component) has an arbiter. The arbiter which is activated to manage the system bus (SYB) and the ones which remain passive is determined during a starting phase. The functional units can be plugged into any plug point and no special component is needed to run the system bus. The invention is applicable in automation systems.

The invention relates to an arrangement with a plurality of plug points (SP1, ..., SP4) which are interconnected via a system bus (SYB) with data and control lines and into which at least one CPU (CP) is plugged and a plurality of functional peripheral devices (PE1, PE2, PE4) can be plugged. The arrangement is constructed in such a way that the CPU (CP) recognises whether functional units (PE1, PE2, PE4) are plugged into the points (SP1, ..., SP4). The invention is applicable to store programmable controls.

摘要:
A mains signalling network (1) for a mains power supply line (2) has a controller (10) that controls switching of appliances (3 to 6) connected to the supply line via respective nodes (30 to 60). Each node has a switch (36) by which a code can be set for the node, the controller having a keyboard (11) for addressing the desired node. When a node receives a signal from the controller, the node generates a reply signal along the supply line (2). The controller generates the signal for controlling the appliance after receipt of the reply signaL if the controller receives signals other than those initiated by the controller, it generates signals to prevent operation of the nodes. Signals from the controller (10) include a code identifying the controller followed by a code identifying a node, whereas reply signals from the nodes include a code identifying that node followed by a code identifying the controller.
