Definitions

  • the sensors can be stimulated via a two-wire bus, which is connected to a power supply unit, to supply the energy to the monitoring device, in each case with alternating signals for delivering correspondingly alternating sensor signals, the data transmission being carried out by clocking the operating voltage, which is applied to active bus connections is maintained via a buffer circuit.
  • the two-wire bus 4 can be connected via an interface 10 to a PC and / or a programmable logic controller.
  • the latter can be used to provide the memories 5, 8 with the necessary information and, if appropriate, with their own checksum. This is possible, for example, using a simple ASCII protocol. When the power is switched on, this data is read from the memories 5, 8 and compared with the checksum and loaded into the memories of the processors 6 ', 6' '.
