摘要:
An electronic device including a physical button, a processing unit and a sensing unit is provided. The processing unit is coupled to the physical button and the sensing unit is coupled to the processing unit. When the electronic device enters a hibernation mode or in a shutdown state, the sensing unit continuously detects a wake-up signal. When receiving the wake-up signal, the sensing unit wakes up the processing unit. The sensing unit further receives an instruction signal externally, generates an instruction information according to the instruction signal, and sends the instruction information to the processing unit. When receiving the instruction information, the processing unit adjusts a corresponding function of the physical button according to the instruction information.

A handheld field maintenance tool includes a training mode. The handheld field maintenance tool has a process communication module operably coupleable to a field device, a user interface, and a controller coupled to the process communication module and the user interface. The controller is configured to interact with a user through the user interface, and is configured to provide a simulation function where at least one characteristic of the field device, indicated through the user interface, is generated by the controller instead of the field device.

A handheld field maintenance tool is provided. The tool includes, among other things, a wireless process communication protocol module configured to communicate in accordance with a wireless process communication protocol. The tool also includes a display and an input device. A controller is coupled to the wireless process communication protocol module, the display, and the input device. The controller is configured to generate a map on the display indicating a position of the handheld field maintenance device relative to at least one asset, such as a field device. The controller is further configured to determine a position of the handheld field maintenance device by triangulating using wireless process communication with a number of known, fixed-position wireless field devices.
摘要:
A handheld field maintenance tool with improved diagnostic functions is provided. The tool includes a process communication module configured to interact with a field device. A controller is coupled to the process communication module. The controller is configured to execute a number of improved diagnostic functions relative to the field device. The controller may obtain contextual information relative to a current field maintenance operation and preload at least one resource relative to a next field operation step. The controller may obtain process alarm information through a wireless communication module, and field device alert information through the process communication module and provide an indication on a display relative to both process alarm information and field device alert information. The controller may execute a sequence of field device maintenance operations on the field device in response to a signal from a user input device. The controller may obtain snapshot information in response to a signal from a user input device.
摘要:
A refrigerating appliance comprising an inner chamber which is surrounded by a heat-insulating housing, and a plurality of electrical or electromechanical components, including a coolant circuit for cooling the inner chamber and at least one temperature sensor, in addition to a control unit for controlling the co-operation of the components. Said control unit has a test operating mode for checking the operativeness of at least some of said components.
摘要:
In the case of an electrical appliance, such as a hob with contact or touch switches under a glass ceramic hotplate, it is possible to provide on at least some contact switches an operating function initiated following double contacting or touching in a time of max. two seconds. If only a single contacting or three or more contacting operations take place within this time period, then no operating function is initiated and instead an error signal is outputted.
摘要:
An intrinsically-safe handheld field maintenance tool includes a process communication module configured communicatively couple to a field device. A camera is configured to obtain at least one image relative to the field device. A controller is coupled to the process communication module and operably coupled to the camera. The controller is configured to store the at least one image relative to the field device. The handheld field maintenance tool may also include or employ an audio input device to capture audio files.
摘要:
A handheld field maintenance tool and associated method are provided. The handheld field maintenance tool includes a process communication module configured to communicate in accordance with a process industry communication standard. A controller is coupled to the process communication module and is configured to access a device description relative to a selected simulated field device. A user interface is configured to receive a user input relative to a parameter of the simulated field device. The controller generates communication through the process communication module to simulate the selected field device based on the user input.
摘要:
An apparatus on a machine tool for machining workpieces, preferably for machining workpieces by removing material, is provided to control functions of the machine tool and to program and/or test the machining of workpieces and/or to test the machine tool itself. The apparatus is provided with at least one display unit and at least one input unit, whereby masks for displaying and/or for inputting, via the input unit, machine and/or control parameters are displayable on the display unit. A start matrix having a grid of fields, which are stored in a geometrically addressable manner and are preferably arranged in rows and columns, can be displayed on the display unit, the input unit which is separate from the display unit being able to be used to select each field via its geometrical position in the grid at which it is displayed on the display unit, and the assigned function being able to be immediately triggered or a mask being able to be immediately displayed on the display unit by activating a field.
摘要:
Operating terminal for a system of devices or a machine, particularly for an automation system, comprising a display used in non-graphic mode, and function keys and a scroll device. The display 13 defines one or two Boolean control actions, particularly to the left and right, with symbols Sa, Sb associated with the text. Each symbol comprises an arrow Fa, Fb and a symbol associated with a Boolean control action (20a, 20b). A side key 16a, 16b is associated with each symbol to apply a control action to the automatic control, this action possibly being held or single pressed in the case of a Boolean control, or possibly dual by using the left and right controls. The terminal can provide a large number of control functions using a display with a small number of lines and only two function keys, while maintaining easy dialogue.
