Definitions

  • the invention relates to a method and a configuration unit for providing an input signal for a signal sink.
  • signals are usually processed.
  • Signal sources that provide these signals are, for example, sensors.
  • Signal values of these signals are, for example, values of a temperature, a pressure, an electrical current, an electrical voltage or a speed. If a signal source fails or the connection to a signal source is faulty or interrupted, the signal from the signal source must be replaced by a substitute value. Substitute values are usually set automatically by the system.
  • the invention is based on the object of specifying a method and a configuration unit for providing an input signal for a signal sink, which are improved in particular with regard to the definition of substitute values.
  • US 2018/172370 A1 discloses a method for controlling the opening of a valve in an HVAC system.
  • the method includes controlling the opening of a six-way valve according to a default control mode depending on a default sensor signal.
  • a default control mode is selected from a first default control mode and a second default control mode. While the valve is controlled in the selected default control mode, it is determined whether the sensor signal is faulty. If the signal is faulty, depending on the selected default control mode, it is switched to controlling the opening of the valve according to a first fallback control mode or an alternative second fallback control mode in which the opening of the valve is controlled independently of the faulty sensor signal.
  • DE 11 2015 000 941 T5 discloses a vehicle-mounted device control unit having at least two redundant operating state detection units.
  • control unit executes actuator drive control based on an operating state detection signal from one of the operating state detection units.
  • control unit executes actuator drive control based on an operating state detection signal of another of the at least two operating state detection units in which no abnormality exists.
  • DE 10 2018 122 371 Al discloses an enhanced modular controller comprising a plurality of configurable communication ports and a control logic layer usable for controlling equipment of a process plant.
  • the communication ports comprise a first set of communication ports and a second set of communication ports that can be used to communicate with one or more nodes of a distributed control system of the process plant.
  • the enhanced modular controller also includes a software layer that accepts port configuration parameters defining one or more port communication rules for the first set of communication ports and for the second set of communication ports.
  • the one or more port communication rules cause the software layer to selectively allow or restrict the forwarding of incoming messages, wherein the incoming messages are received at the first or second set of communication ports.
  • an input signal for a signal sink is provided by means of a configuration unit, wherein the configuration unit is set up,
  • the configuration unit therefore enables a user to define a replacement value for a signal value of a signal source if the signal source does not deliver a signal value, for example because the signal source fails or the connection to the signal source is disturbed or interrupted.
  • This allows a user-specific replacement value to be defined, or the replacement value can be adapted by the user to suit his or her requirements, in contrast to, for example, a replacement value automatically set by the system.
  • the configuration unit is set up to determine signal sources adapted to the type of input signal and to enable the user to select the signal source from these signal sources.
  • the aforementioned embodiment of the method according to the invention enables the user of the configuration unit to determine the signal source himself.
  • the configuration unit determines signal sources adapted to the type of input signal, from which the user can select a signal source. For example, the configuration unit is set up to determine signal sources for this selection whose signal values correspond to a signal source adapted to the input signal. physical quantity. For example, if the physical quantity of the input signal is a temperature, the configuration unit determines as signal sources that can be selected by the user, for example, signal sources whose signal values are temperature values.
  • the configuration unit is set up to enable the user to select a replacement signal source whose signal value is used as a replacement value for the definition of the replacement value as a replacement for the signal source.
  • the configuration unit offers the user a selection of replacement signal sources for defining the replacement value. By selecting one of these replacement signal sources, the signal value supplied by this replacement signal source is defined as the replacement value.
  • the configuration unit is set up to determine a preselection of replacement signal sources adapted to the type of input signal and to enable a user of the configuration unit to restrict the selection of the replacement signal source to this preselection.
  • the selection of the replacement signal sources by the user can be restricted to a pre-selection determined by the configuration unit.
  • the pre-selection of the replacement signal sources is adapted to the type of input signal of the signal sink. For example, the pre-selection restricts the selectable replacement signal sources to replacement signal sources whose signal values correspond to a value adapted to the input signal. physical quantity. If the physical quantity of the input signal is, for example, a temperature, the preselection restricts the selectable substitute signal sources to substitute signal sources whose signal values are temperature values. Such a preselection of substitute signal sources makes it easier for the user to select a substitute signal source and reduces the risk of errors when the user selects the substitute signal source.
  • the provision of a preselection of substitute signal sources by the configuration unit can be activated and deactivated by the user, so that the user can decide for himself whether to make use of the preselection or not.
  • the configuration unit is set up to enable a user of the configuration unit to define a fixed value as a replacement value.

  • the configuration unit is set up to enable a user of the configuration unit to define a fixed value as a replacement value for the signal value even if the signal source supplies a signal value.
  • the configuration unit enables a user to define a fixed value as a replacement for a signal source regardless of whether the signal source has a Signal value provides .
  • the fixed value completely replaces the signal source .
