Definitions

  • Another way of generating the code sequence or code signal according to claim 5 is that the mechanical force at Press the safety opening switch to generate a short one electronic signal is used. In this case there is an additional one Power supply and the necessary wiring effort dispensable. It is only necessary that the safety opening switch is modified accordingly.
  • Each code signal generator therefore sets when the assigned safety opening switch is actuated a unique code sequence either the safety path formed by the line sections or on the additionally provided single diagnostic line.
  • the safety path (Safety line and safety line sections) is in normal, closed state closed.
  • the code signal generators are preferably designed according to claim 7.
  • An advantageous development of this embodiment can be seen Claim 8.
  • the invention has the advantage that the star-shaped wiring of the diagnostic contacts omitted and thus the cabling effort on the safety path can be reduced. Beyond that no individual Diagnostic inputs on the evaluation unit required. this means Additional savings in the area of decentralized inputs and outputs.
  • the evaluation of test signals is already in intelligent controls or decentralized inputs and outputs, so that there is no major additional Development effort is necessary.
  • an evaluation unit 11 has a test-in connection 23, a test-out connection 24 and a voltage supply connection 25 on.
  • Each opening switch 12a, 12b, 12c is a closing switch 17a, 17b, 17c associated with the opening of the associated opening switch 12a, 12b, 12c closes.
  • the closing switches 17a, 17b, 17c are on the one hand with a code signal generator 13a, 13b, 13c and on the other hand with the input 14a, 14b, 14c of the associated opening switch 12a, 12b, 12c connected.
  • the generators 13a, 13b, 13c are designed so that each one of them characteristic for the assigned opening switch 12a, 12b, 12c Code signal or a characteristic code sequence can generate as soon as the assigned opening switch 12a, 12b, 12c opens or the assigned one Closing switch 17a, 17b, 17c closes.
  • the code signal arrives either via the line section 16a or the line sections 16a, 16b and the closed opening switch 12a or the line sections 16a, 16b, 16c and the closed opening switches 12a, 12b to the test-in connection 23 of the evaluation unit 11, where due to the Content of the individual code signals or code sequences is recognized, which the opening switch 12a, 12b, 12c has addressed.
  • the opening switch 12b opens on a transfer line or a conveyor belt 12b either automatically or due to manual actuation, whereupon the safety path is interrupted and the evaluation unit 11 signals a fault via the test-in / test-out connections 23, 24 becomes.
  • the signal output 21 of the microprocessor 19 is via the amplifier 20 either to the assigned safety line section 16a, 16b, 16c or the diagnostic line 15 (FIG. 2).
  • the microprocessor 19 has the characteristic Transmits code signal continuously, the closing switches 17a, 17b, 17c in the path between the signal output 21 and the connection point (14b) of the amplifier 20 would have to be provided. Is preferred in this case the closing switch 17a, 17b, 17c is provided at the output of the amplifier 20.
  • Inexpensive small microprocessors are available for the application according to the invention, e.g. the PIC 12C508 (8-pin, 8 bit S08 housing) from Microchip available.
