Examples

This example creates two ScpiPowerSupplyModule instances for a power supply with two outputs.

var serialPort = new SerialPortModule("serialPort") { Encoding = Encoding.ASCII, EndDelimiter = Encoding.ASCII.GetBytes("\r\n") };
var powerSupply1 = ScpiPowerSupplyModule("PowerSupply1", serialPort) { InstrumentNumber = 1 };
var powerSupply2 = ScpiPowerSupplyModule("PowerSupply2", serialPort) { InstrumentNumber = 2 };

Remarks

To use a power supply with multiple outputs, create multiple instances of the ScpiPowerSupplyModule class with the same ICommunication instance. Set the InstrumentNumber of each ScpiPowerSupplyModule instance.

Constructors

ScpiPowerSupplyModule(string, ICommunication)

Initializes a new instance of the ScpiPowerSupplyModule class.

public ScpiPowerSupplyModule(string name, ICommunication communicationPort)

Parameters

name string

Name for the device.

communicationPort ICommunication

Port for communication with the device.

Remarks

The encoding of the communicationPort should be ASCII, and the EndDelimiter should be "\r\n".

Properties

InitializationState

Gets or sets a value indicating whether the object is initialized.

public InitializationState InitializationState { get; protected set; }

Property Value

InitializationState

InstrumentNumber

Gets or sets the instrument number.

[Configuration(0, Description = "For only one power supply unit the default value is 0. In case of multiple power supply units, the desired output is selected.")]
public int InstrumentNumber { get; set; }

Property Value

int

MaximumCurrent

Gets or sets maximum current in ampere.

[Configuration(0, Unit = "A")]
public override double MaximumCurrent { get; set; }

Property Value

double

MaximumVoltage

Gets or sets maximum voltage in volt.

[Configuration(0, Unit = "V")]
public override double MaximumVoltage { get; set; }

Property Value

double

ReloadValuesFromDeviceIsActive

Gets or sets a value indicating whether the value setting methods reload the values from the device.

[Configuration(true, Description = "Indicates whether the set point should be read back after a set point change.")]
public bool ReloadValuesFromDeviceIsActive { get; set; }

Property Value

bool

Remarks

Default is false. For example if true, SetpointCurrent sets the value and sets the SetpointCurrent with device value.

SubModules

Gets the sub LisrtModules.

public ILisrtModuleCollection SubModules { get; }

Property Value

ILisrtModuleCollection

Methods

Exit()

De initializes the object.

public virtual void Exit()

Remarks

Sets the voltage to 0V, current to 0A and disables the output.

Initialize()

Initializes the object.

public virtual void Initialize()

MeasureCurrent()

Measures the current.

public virtual double MeasureCurrent()

Returns

double

The measured current in ampere or 0.0 if disabled.

Exceptions

NotInitializedException

Thrown when the module is not initialized.

MeasureVoltage()

Measures the voltage.

public virtual double MeasureVoltage()

Returns

double

The measured voltage in volt or 0.0 if disabled.

Exceptions

NotInitializedException

Thrown when the module is not initialized.

SetCurrent(double)

Sets the current.

public override void SetCurrent(double current)

Parameters

current double

Current in ampere to regulate.

Exceptions

NotInitializedException

Thrown when the module is not initialized.

ArgumentOutOfRangeException

Thrown when current is greater than MaximumCurrent.

SetOutput(bool)

Sets the output.

public override void SetOutput(bool isEnabled)

Parameters

isEnabled bool

State for the output.

Exceptions

NotInitializedException

Thrown when the module is not initialized.

SetVoltage(double)

Sets the voltage.

public override void SetVoltage(double voltage)

Parameters

voltage double

Voltage in volt to regulate.

Exceptions

NotInitializedException

Thrown when the module is not initialized.

ArgumentOutOfRangeException

SetVoltageAndCurrent(double, double)

Sets the voltage, current and enables the output.

public override void SetVoltageAndCurrent(double voltage, double current)

Parameters

voltage double

Voltage in volt to regulate.

current double

Current in ampere to regulate.

Exceptions

NotInitializedException

Thrown when the module is not initialized.

ArgumentOutOfRangeException

Thrown when voltage is greater than MaximumVoltage or current is greater than MaximumCurrent.
