In the use of a display of a converter, method for operating a converter, and converter, the converter having an address code switch, in particular on its housing, and in an actuation of the address code switch and during a subsequent, predefined period of time, a respective value corresponding to the respective switch position of the address code switch is displayed by the display. Operating information of the converter is displayed in all other cases.

An improved comfort control system for controlling an environment regulation system includes a processing unit, a video interface, an input subsystem, a hierarchy of switching mechanisms and a special computer program. The hierarchy of switching mechanisms includes an electronic switching mechanism having a jumper and a second tier switching mechanism implemented by the special computer program and including a key combination. When the control device is in an operation mode and the jumper is in an enabled position, entering the key combination causes the special computer program to switch the comfort control system to the configuration mode. When the comfort control system is in an operation mode and the jumper is in a disabled position, the special computer program does not switch the control device to the configuration mode from the operation mode.

A control system for mechanical equipment is provided with: a manual operation mechanism provided with a minimum required number of operation switches and a mechanical equipment identification signal transmission unit for transmitting a mechanical equipment identification signal that identifies mechanical equipment; an operation assistance terminal in which the mechanical equipment identification signal received from the transmission unit is used as a basis to display a manual operation assistance screen including a manually operated device selection section and a control content display section that displays control content assigned to the operation switches of the manual operation mechanism for a selected manually operated device; and a control device that connects the control unit of an identified control target device and the operation switches of the manual operation mechanism by receiving a control target device switching signal identified by operation of the manually operated device selection section.

An irrigation controller is revealed. The irrigation controller includes a user interface presenting information to users, easily-operated by buttons and allowing users to program irrigation related information directly. The user interface is composed of a round display, a plurality of program keys, and a selective key. An indicator and programmable information zones are shown on the round display. There are at least six programmable information zones. The information zone is selected by a single selective key. The indicator is moved in one direction in a circular path.

A communication system for use with a well tool can include an of outer toroid antenna. The outer toroid antenna can be positionable around an outer housing of the well tool. The communication system can also include an inner toroid antenna positionable within the outer housing of the well tool. The communication system can further include a switch coupled to the outer toroid antenna and the inner toroid antenna. The switch can be operable to enable or disable a wireless communication via the outer toroid antenna or the inner toroid antenna.

A method for determining a physical connection topology of a test device with real-time capability and set up for control device development includes: determining logical communication links between a plurality of simulation models; and automatically determining the physical connection topology by specifying direct physical communication links between the plurality of data processing units based on the respective specified quantities of physical interfaces of the plurality of data processing units. Specifying the direct physical communication links includes determining, for each of the logical communication links, whether a direct physical communication link corresponding to the logical communication link forms part of the physical connection topology.

Provided are a programmable motor and a household appliance having the same. The programmable motor comprises a main body (21) and a driving device (22) comprising a reprogramming interface. When performing reprogramming on the programmable motor, the reprogramming interface communicates with a programming device to receive a motor parameter or a motor software program, to transmit the same to the driving device (22), and to update the motor parameter or the motor software program in the driving device (22). The method realizes rewriting of a motor software program and realizes reprogramming of a motor by directly inserting a programming device into a reprogramming interface of a driving device (22) without having to disassemble the driving device (22), thereby effectively reducing post-sale costs associated with a motor, and improving post-sale efficiency associated with the motor.

An expandable irrigation controller for controlling a plurality of watering stations in an irrigation system includes a removable front panel and an inner housing, connected to the front panel. The inner housing includes a circuit board including control connectors which are connected electrically to the controller and a station module operable to provide an ON/OFF signal to at least one watering station of the irrigation system. The station module is electrically connected to the circuit board via the control connectors and the ON/OFF signal is provided based on instructions from the controller in accordance with the watering program. The control connectors are positioned in a substantially continuous line extending across the inner housing such that the station module is connectable to the control connectors at substantially any desired location. Multiple modules of different sizes may be mounted in the inner housing as desired.

A configuration system for reconfiguring a switch cabinet includes a detection unit which detects functional units of an electric circuit, which are mounted within a switch cabinet, by way of characteristic features of the functional units, which have unambiguous identification features which are read out by the detection unit. A configuration unit contains a processor, which calculates an electric circuit diagram of the electric circuit on the basis of the functional units of the electric circuit which are detected by way of the characteristic features and automatically replaces the detected functional units of the calculated circuit diagram with associated replacement functional units which are stored in a database. An output unit is provided for outputting the determined replacement functional units.

An output unit, an input unit and an input-output system are provided to construct a safety control logic having a high degree of freedom in design and has scalability. The output unit includes an input signal receiving part, receiving an input signal from the input unit; and an output control part, performing an output based on the input signal. In each group set for the output unit, the output unit performs the output when receiving the input signals from all the input units set to the same group as the group set for the output unit.
