An HMI system with a mobile control and monitoring device for automation components of a technical system is provided. The HMI system includes means for a contactless data transmission between the mobile control and monitoring device and the automation components, a manual device for triggering or blocking security relevant operations of the technical system and means for locating the mobile control and monitoring device. Evaluation means are provided for managing an active operational area which activate the automation components for security-relevant operations of the technical system via the mobile control and monitoring device solely when the manual device is released and the locating means detect that the mobile control and monitoring device is located inside the active operational area. Is he manual device placed directly on the housing of the technical system, an operator has to approach such that he/she enters the active operational area in a secure manner.

Mobile control and monitoring system

A device for communicating with a system, especially for operating and monitoring an automated industrial manufacturing system is described. The device contains a mobile communication device for wireless exchange of data with the system. Further, the device also includes a fixed installed connection for the communication device and a sensor recognizing whether the communication device is connected to the fixed installed connection.

Device for communicating with a system

There is described a method for enabling the operation of automation components of a technical system via a mobile control and monitoring device. In a first step, the control and monitoring device receives a first identification from a first transponder device, with the first transponder device being attached to the technical system, with the first transponder device having been activated by the automation components and with the first identification having been transmitted via a wireless communication connection from the automation components to the mobile control and monitoring device. In a further step the communication connection between the control and monitoring device and the automation components is deactivated. The mobile control and monitoring device sends a carrier signal and following that receives the carrier signal modulated by the first transponder device. A first distance between the control and monitoring device and the first transponder device is then determined from the modulated carrier signal. In addition, a first radio-determined identification from the first transponder device is determined from the modulated carrier signal. Following the reception of the modulated carrier signal, the communication connection is reactivated. If the first distance is shorter than a predetermined first distance and if the radio-determined first identification corresponds to the first identification, the operation of the automation components is enabled.

The HMI system is provided with a mobile control and monitoring device for automation components of a technical system. It comprises means for contactless data transmission between the mobile control and monitoring device and the automation components, a manual device for triggering or blocking security relevant operations of the technical system and means for locating the mobile control and monitoring device. Evaluation means are provided for managing an active operational area and which activate the automation components for security-relevant operations of the technical system via the mobile control and monitoring device solely when the manual device is released and the locating means detect that the mobile control and monitoring device is located inside the active operational area, the advantage thereof being that manual triggering of security-relevant operations by an operator is the condition upon which they can be activated via the mobile control and monitoring device. If the manual device is placed directly on the housing of the technical system, for example, an operator has to approach in such a way that he/she enters the active operation are in a secure manner.

The invention relates to a method and a device for communication with a plant, in particular, for the operation and monitoring of an automated plant in industrial manufacture. The state of charge of the battery, in a battery-operated communication device, for exchange of data with the plant, is recorded. The predicted remaining operation time of the communication device is determined from the state of charge and, depending on the state of charge, measures are taken in the plant, or in the communication device.

A retaining device includes bearing units () that float-mount a flat screen () and that are preferably each provided with at least one elastic-positioning element () and a vibration damping element (). The elastic-positioning element preferably includes a cylinder-shaped hard rubber spacer element (). The vibration-damping element () preferably includes a damper with an annular plate-shaped housing and a gel filling (). Vibrations and shocks are introduced substantially centrally into the vibration-damping element via a tappet (). The retaining device is advantageously used in an electronic display device to float-mount a flat screen, configured e.g. as an LCD display unit, in combination with a touch screen as a contact-sensitive unit.

The invention relates to a system for coupling a mobile data input unit to a field bus, whereby a coupling unit is connected to the field bus via a spur line and a line driver and the signals at the output of the line driver are supplied to a coupling link or received from the latter via first level converters. The mobile data input unit receives the signals from the coupling link or supplies them to the latter via second level converters.
