Digital Probe

Description of the Digital Probe component in Schematic Editor.

Description

The Digital Probe component adds a signal to the digital signal list in HIL SCADA/TyphoonSim Scope.

The signal connected to Digital Probe can be also read using HIL API commands read_digital_signal and read_digital_signals.

Any signal can be connected to a digital probe. The value of the signal will be converted to Boolean. Non 0 values are converted as True and 0 is converted to False

If the input is a vector, SCADA will split the signal so that each vector element can be read separately.In TyphonSim, vectorized input is not supported yet.

Enabling the Signal Streaming property allows the acquisition and logging of the signal.In TyphonSim, enabling this property will have no effect on simulation

Ports

  • In (in)
    • Port to which the signal intended to be measured is connected.
      • Supported types: uint, int, real.
      • Vector support in real-time simulation: yes
      • Vector support in TyphoonSim: no

General (Tab)

  • Override signal name
    • Check this checkbox to override the signal name. Instead of using the default signal names (for example, Subsystem1.Subsystem2.Probe1), a custom signal name can be specified.
  • Signal streaming
    • Signal streaming is ignored in TyphoonSim and changing its value will not affect TyphoonSim simulation at all.
    • Check this checkbox for allowing acquisition and logging of the signal at a medium sample rate. For more details on signal streaming, please refer to link : Signal streaming
  • Execution rate
    • Type in the desired signal processing execution rate. This value must be compatible with other signal processing components of the same circuit: the value must be a multiple of the fastest execution rate in the circuit. There can be up to four different execution rates. To specify the execution rate, you can use either decimal (e.g. 0.001) or exponential values (e.g. 1e-3) in seconds. Alternatively, you can type in ‘inherit’ in which case the component will be assigned execution rate based on the execution rate of the components it is receiving input from.

Extras (Tab)

The Extras tab gives you the opportunity to set Signal Access Management for the component.
Signal visibility is calculated based on the 'signal_access' property and whether or not a parent component in its hierarchy is locked or not. Components that are not contained within locked components expose their signals regardless of the 'signal_access' property. The 'signal_access' property can have one of three values:
  • Public - Components marked as public expose their signals on all levels.
  • Protected - Components marked as protected will hide their signals to components outside of their first locked parent component.
  • Inherit - Components marked as inherit will take the nearest parent 'signal_access' property value that is set to a value other than inherit.
