Parameters:	uid – Type: string ipcon – Type: IPConnection
Returns:	industrialDualAnalogIn – Type: BrickletIndustrialDualAnalogIn

Creates an object with the unique device ID uid:

If you want to get the voltage periodically, it is recommended to use the VoltageCallback callback and set the period with SetVoltageCallbackPeriod().

• VoltageReachedCallback

is triggered, if the threshold

• SetVoltageCallbackThreshold()

keeps being reached.

long BrickletIndustrialDualAnalogIn.GetDebouncePeriod()¶

Returns:	debounce – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 100

Returns the debounce period as set by SetDebouncePeriod().

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done by appending your callback handler to the corresponding event:

void MyCallback(BrickletIndustrialDualAnalogIn sender, int value)
{
    System.Console.WriteLine("Value: " + value);
}

industrialDualAnalogIn.ExampleCallback += MyCallback;

The available events are described below.

event BrickletIndustrialDualAnalogIn.VoltageCallback(BrickletIndustrialDualAnalogIn sender, byte channel, int voltage)¶

Callback Parameters:	sender – Type: BrickletIndustrialDualAnalogIn channel – Type: byte, Range: [0 to 1] voltage – Type: int, Unit: 1 mV, Range: [-35000 to 35000]

This callback is triggered periodically with the period that is set by SetVoltageCallbackPeriod(). The parameter is the voltage of the channel.

The VoltageCallback callback is only triggered if the voltage has changed since the last triggering.

event BrickletIndustrialDualAnalogIn.VoltageReachedCallback(BrickletIndustrialDualAnalogIn sender, byte channel, int voltage)¶

Callback Parameters:	sender – Type: BrickletIndustrialDualAnalogIn channel – Type: byte, Range: [0 to 1] voltage – Type: int, Unit: 1 mV, Range: [-35000 to 35000]

This callback is triggered when the threshold as set by SetVoltageCallbackThreshold() is reached. The parameter is the voltage of the channel.

If the threshold keeps being reached, the callback is triggered periodically with the period as set by SetDebouncePeriod().

Virtual Functions¶

Virtual functions don't communicate with the device itself, but operate only on the API bindings device object. They can be called without the corresponding IP Connection object being connected.

byte[] BrickletIndustrialDualAnalogIn.GetAPIVersion()¶

Output Parameters:	apiVersion – Type: byte[], Length: 3 0: major – Type: byte, Range: [0 to 255] 1: minor – Type: byte, Range: [0 to 255] 2: revision – Type: byte, Range: [0 to 255]

Returns the version of the API definition implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

bool BrickletIndustrialDualAnalogIn.GetResponseExpected(byte functionId)¶

Parameters:	functionId – Type: byte, Range: See constants
Returns:	responseExpected – Type: bool

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by SetResponseExpected(). For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

• BrickletIndustrialDualAnalogIn.FUNCTION_SET_VOLTAGE_CALLBACK_PERIOD = 2
• BrickletIndustrialDualAnalogIn.FUNCTION_SET_VOLTAGE_CALLBACK_THRESHOLD = 4
• BrickletIndustrialDualAnalogIn.FUNCTION_SET_DEBOUNCE_PERIOD = 6
• BrickletIndustrialDualAnalogIn.FUNCTION_SET_SAMPLE_RATE = 8
• BrickletIndustrialDualAnalogIn.FUNCTION_SET_CALIBRATION = 10

void BrickletIndustrialDualAnalogIn.SetResponseExpected(byte functionId, bool responseExpected)¶

Parameters:	functionId – Type: byte, Range: See constants responseExpected – Type: bool

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

• BrickletIndustrialDualAnalogIn.FUNCTION_SET_VOLTAGE_CALLBACK_PERIOD = 2
• BrickletIndustrialDualAnalogIn.FUNCTION_SET_VOLTAGE_CALLBACK_THRESHOLD = 4
• BrickletIndustrialDualAnalogIn.FUNCTION_SET_DEBOUNCE_PERIOD = 6
• BrickletIndustrialDualAnalogIn.FUNCTION_SET_SAMPLE_RATE = 8
• BrickletIndustrialDualAnalogIn.FUNCTION_SET_CALIBRATION = 10

void BrickletIndustrialDualAnalogIn.SetResponseExpectedAll(bool responseExpected)¶

Parameters:	responseExpected – Type: bool

Changes the response expected flag for all setter and callback configuration functions of this device at once.

Constants¶

int BrickletIndustrialDualAnalogIn.DEVICE_IDENTIFIER¶

This constant is used to identify a Industrial Dual Analog In Bricklet.

The GetIdentity() function and the IPConnection.EnumerateCallback callback of the IP Connection have a deviceIdentifier parameter to specify the Brick's or Bricklet's type.

string BrickletIndustrialDualAnalogIn.DEVICE_DISPLAY_NAME¶

This constant represents the human readable name of a Industrial Dual Analog In Bricklet.
