Abstract: Configuration of a building. A method of configuring a site, the site comprising a plurality of devices (11-23), the plurality of devices (11-23) comprising a plurality of site controllers and a plurality of sensors and a plurality of appliances, the method comprising the steps of: selecting a first device (11-23) from the plurality of appliances and/or from the plurality of sensors; producing first descriptor data for the first device (11-23); selecting a second device (11-23) from the plurality of appliances and/or from the plurality of sensors; producing second descriptor data for the second device (11-23); loading data indicative of an ontology database (9), the ontology database comprising a set of rules; producing relationship data by applying one or more rules to the first and second descriptor data; selecting a third device (11-23) from among the controllers.

Abstract: Flexible control is provided in building automation. By dividing a floor space into segments, different segments may be assigned to rooms. The operation of the building automation likewise includes room level and segment level control functions and corresponding objects. To assign or reassign a given segment to a room, the segment is linked to the room using an identifier of the corresponding room control function. The building automation equipment and corresponding control for the segment is linked to the room operation. The separation of the room and segment functions may avoid any or extensive manual engineering other than re-assignment. The assignment or reassignment of segments to rooms may be performed online (e.g., at a panel or management station), offline (e.g., at a computer or engineering station), or automatically (e.g., moveable wall system).

Abstract: An interlock function block system, method, and apparatus that reduces the necessity for a building automation programmer to program low-level instructions using a complex series of ANDs, ORs, and arithmetic functions to protect such devices is provided.

Abstract: A common automation system controller configured using a hierarchical approach for use in a building automation system.

Abstract: An apparatus for controlling and/or regulating process parameters of an installation such as a building automation installation has at least a first decision table and preferably a second decision table. The decision tables have rules with which a priority is associated. By evaluating the rules of the first decision table, on the basis of the state of a sub-system of the installation, a further state value is ascertained and fed to an input of the second decision table. The state of a further sub-system of the installation is altered by evaluation of rules of the second decision table. The decision tables can be represented for an installation operator in a picture screen window.

Abstract: An arrangement for converting a multiphase electric signal into a frequency is disclosed. Illustratively, the arrangement comprises an adder circuit for adding the individual phases comprising said multiphase signal. The arrangement also comprises one first polarity reversing switch for each phase in the multiphase signal. A voltage/current converter is connected downstream of the first polarity reversing switches. At least one second polarity reversing switch is connected downstream of the voltage/current converter. A control circuit generates a periodic switch-over signal for controlling the first and second polarity reversing switches. In addition, a constant current source is connected to an input of the second polarity reversing switch.

Abstract: A circuit arrangement for summing power outputs is disclosed. The circuit arrangement is especially useful in connection with a multi-phase electricity meter. The arrangement includes a plurality of input circuits connected in sequence, each of which has a current-to-voltage converter and a multiplier connected to the current-to-voltage converter. A voltage-to-frequency converter is connected at the output of each multiplier. Starting, at least with the second input circuit in the sequence, an adder is connected to the voltage-to-frequency converter by means of two inputs of the adder. Two other inputs of the adder are connected to two outputs of the preceding input circuit in the sequence. Illustratively, two outputs of each adder form two outputs of the corresponding input circuit. A ternary encoder followed by a ternary decoder may be located between the outputs of one input circuit and the adder of the succeeding input circuit.
