The invention relates to a touch panel device for a dimmer lighting control system, the device comprising a touch sensitive surface capable of detecting a touch input; a light sensor that detects ambient light levels within a sensing area adjacent to the device; a processing means operatively connected to the touch sensitive surface and the light sensor for generating control signals based on detection of the touch input on the touch sensitive surface and/or ambient light levels wherein, in use, the total light output of a light circuit can be controlled manually with the touch panel device and/or controlled autonomously by the level of ambient light in the sensing area.

A touch switch capable of taking up new functions, electrically connected to at least one electrical appliance device, includes a touch display module, a processing unit, and control modules. The touch display module displays a function icon, receives a touch message, and senses ambient temperature, ambient brightness, and human body motion in close vicinity. The processing unit receives the touch message and triggers the electrical appliance device to undergo a switching motion. The control modules each have an operating function corresponding to one of the electrical appliance devices to start the operating function corresponding to the touch message after the processing unit has received the touch message so that the electrical appliance device corresponding to the operating function undergoes the execution motion. The touch switch integrates and controls the electrical appliance devices and enables users to select an appropriate one of the control modules as needed, thereby achieving customization.

Technical installation data are visually preprocessed in a targeted manner in a control room or on a tablet with a touchscreen in mobile use by presenting a priority matrix. For this purpose, the interference messages are sorted, for example, horizontally with descending priority from left to right and vertically according to the installation part and are output. This largely relieves an operator of analysis and prioritization of the interference messages. The operator can therefore identify, locate and eliminate the most important interference messages in a shorter time. The number of priorities and installation parts considered is flexible since the matrix can be scaled to a wide variety of installation types, installation sizes and processes. All technical installation data relevant to assessing the situation are combined in one view. A second display area with a logical view is used to provide an overview of the complete industrial installation.

A work machine display device is provided with a touch panel which displays software buttons and operation conditions which are necessary for selecting the software buttons at the same time in a state in which the software buttons and the operation conditions are related.
