Definitions

  • the present invention relates to a control device to control or regulate a safety-critical component with a switching device that a first switch and a second switch connected in series with the first for switching the safety-critical component, a first control device for receiving an input signal and output of a first control signal and one second control device for recording the input signal and output a second drive signal.
  • the present invention relates to a corresponding one Process for controlling or regulating a safety-critical Component.
  • the controller that is in master mode reads all inputs and sets the output states of the Switches with which it is connected or the are assigned to him. Important states like requirements compared with the slave and internal tests are carried out.
  • An emergency stop request is first made by the controller in the Master mode registered.
  • the disadvantage is that those outputs controlled by the controller in slave mode can only be switched off when transmit the EMERGENCY STOP request from the master to the slave has been. Those exits immediately from Masters can be switched off relatively quickly become. So the response time is to switch off of the controlled components depends on which controller receives the request first and whether the desired one Output can also be switched off by this controller.
  • the object of the present invention is therefore a control device and a corresponding method for Controlling or regulating a safety-critical component to propose with an average shortened response time.
  • this object is achieved by a control device to control or regulate a safety-critical Component with a switching device that a first Switches and a second one connected in series with the first Switch for switching the safety-critical component has, a first control device for recording an input signal and output of a first control signal and a second control device for recording the input signal and output of a second control signal, wherein the first switch of the switching device from the first control device and the second switch of the Switching device can be controlled by the second control device are.
  • a method for Controlling or regulating a safety-critical component by providing a switching device that a first Switches and a second one connected in series with the first Switch for switching the safety-critical component has, providing a first control device, which is connected to the switch, and a second Control device connected to the second switch is recording an input signal and outputting a first one Control signal from the first control device the first switch of the switching device based on the Input signal, based on the input signal second control signal from the second control device output to the second switch of the switching device becomes.
  • the invention is based on the idea that the output should be switched off, regardless of which of the Switch is turned off first. Because now both Controllers or control devices the series connection control from the two switches and thus one AND connection of the outputs of the controller is given the output at the switching device is definitely with the shorter response time of the two controllers.
  • a positive side effect of this time-shifting is that a simultaneous welding of the two switches, z. B. Sagittarius can be excluded.
  • the EMERGENCY STOP function is therefore one of the contacts even after welding the switch is still guaranteed.
  • the timed switching off of the switches still has the The advantage of having approximately the same lifespan for both switches are to be expected. This is because in statistical Each switch means just as often in the current-free as in the energized state is switched off.
  • the first and second switches in the Switching device each by a relay or a contactor realized.
  • the first and second switches can also be designed as a semiconductor switch or an optocoupler include.
  • the first and second switches can be staggered from one another can be controlled. Furthermore, the first and second control device work according to the master-slave principle, whereby there is a defined time offset. Specially created then the time offset by the amount of time the master needed to notify the slave of an event put.
  • the control device can especially for the safety shutdown respectively EMERGENCY STOP control can be used.
  • FIG. 2 shows a waveform diagram or State diagram of the individual components.
  • the EMERGENCY STOP switch at input X is pressed.
  • controller C1 reads input X.
  • the output unit Y1 becomes certain reaction time at the time t1 switched off. Since the controller C2 at time t0 was not active, it must first be pressed by controller C1 of the EMERGENCY STOP switch to be informed to the output unit Turn off Y2. The response time is therefore corresponding longer and the output unit Y2 only becomes Time t2 switched off.
  • the invention can Control device in a security device, for example of the applicant's 3TK2845 series, with two potential-free Relay outputs that are connected in series are used become.
  • the response time is Masters on an EMERGENCY STOP request up to 8 ms.
  • the time for transmitting the emergency stop request from the mater to the slave can be up to 15 ms.
  • the relay's fall time is in the present example a maximum of 12 ms.
