Definitions

  • the invention relates to an electrical device with a control element, which enables activation of a function assigned to the operating element in a first operating mode and which does not enable activation of the function associated with the operating element in a second operating mode.
  • a so-called Mobile Panel 277 has an operating element in the form of a STOP button, which is arranged clearly visible on the panel and is only activated or ready for operation if the panel is communicatively connected to a secure radio range of a machine. Otherwise, this STOP button is not ready for operation, which means that pressing the button by an operator is irrelevant and no reaction is triggered.
  • Such a non-activated or not operable button is particularly hindering for an operator if it does not recognize that the button is not ready for use; because it may happen that an operation of a machine or an intervention in a technical process to be controlled due to disturbances is required and the non-operational button is operated in vain.
  • the present invention has for its object to provide an electrical device of the type mentioned, which largely avoids the operation of a non-operational control element.
  • the electrical device is provided with a device which shifts the operating element in the second mode in a recess in the device.
  • the device has a cover plate, which covers the operating element in the second operating mode. This ensures that an inoperable control element is not accessible to an operator.
  • FIG. 1 an electrical device in the form of a mobile operating and monitoring device 1 is shown, which is suitable for a machine and / or plant operation.
  • This has a touch screen 2, programmable function keys 3 and an operating element in the form of a button 4, which is only ready for operation if the operating and monitoring device 1 is in a secure radio range of a machine, not shown, which the operating and monitoring device. 1 operated and exchanged with this information.
  • the button 4 is z. B. the function "off machine” assigned, which in a first mode in which the button 4 is activated or ready for operation, the machine can be turned off by pressing a button. In the event that the mobile HMI device 1 is not within the radio range of the machine, the button 4 is not ready. In this second mode, the machine can not be turned off via the button 4, ie, the function "switch off machine" assigned to the button 4 can not be executed in this case, the button 4 is not ready for operation.
  • buttons 4 any functions. For example, next to the function "switch off the machine", the button 4 can also be assigned the function "switch on the machine".
  • the operating and monitoring device 1 knows the current state of the machine. This means that the operating and monitoring device 1 "knows” whether the machine is switched on or off, and according to this knowledge assigns the button 4 the corresponding current function "switch off the machine” or "switch on the machine”.
  • FIGS. 2 to 4 in which in a simplified representation of a button of a control and monitoring device is shown.
  • the button In the event that the button is ready, this is easily visible to an operator, regardless of whether the button is pressed or not.
  • the button In the event that the button is not ready, what an evaluation unit 5 due to lack of communication data between the machine and the operating and monitoring device, the button "pulls" itself back into a recess of the operating and monitoring device.
  • the evaluation unit 5 controls a mechanical device in the form of a gear drive 6 such that the button is lowered.
  • a hydraulic, magnetic or other suitable drive is possible.
  • a cover which covers the button, the evaluation unit 5 drives a suitable drive to push the cover over the button.
