API

Generally, every method of the C# bindings that returns a value can throw a Tinkerforge.TimeoutException. This exception gets thrown if the device did not respond. If a cable based connection is used, it is unlikely that this exception gets thrown (assuming nobody plugs the device out). However, if a wireless connection is used, timeouts will occur if the distance to the device gets too big.

Since C# does not support multiple return values directly, we use the out keyword to return multiple values from a method.

The namespace for all Brick/Bricklet bindings and the IPConnection is Tinkerforge.*.

All methods listed below are thread-safe.

Basic Functions

class BrickletIndustrialAnalogOut(string uid, IPConnection ipcon)
Parameters:
  • uid – Type: string
  • ipcon – Type: IPConnection
Returns:
  • industrialAnalogOut – Type: BrickletIndustrialAnalogOut

Creates an object with the unique device ID uid:

BrickletIndustrialAnalogOut industrialAnalogOut = new BrickletIndustrialAnalogOut("YOUR_DEVICE_UID", ipcon);

This object can then be used after the IP Connection is connected.

  • 0V to 5V
  • 0V to 10V

Possible current ranges are:

  • 4mA to 20mA
  • 0mA to 20mA
  • 0mA to 24mA

The resolution will always be 12 bit. This means, that the precision is higher with a smaller range.

The following constants are available for this function:

For voltageRange:

  • BrickletIndustrialAnalogOut.VOLTAGE_RANGE_0_TO_5V = 0
  • BrickletIndustrialAnalogOut.VOLTAGE_RANGE_0_TO_10V = 1

For currentRange:

  • BrickletIndustrialAnalogOut.CURRENT_RANGE_4_TO_20MA = 0
  • BrickletIndustrialAnalogOut.CURRENT_RANGE_0_TO_20MA = 1
  • BrickletIndustrialAnalogOut.CURRENT_RANGE_0_TO_24MA = 2
void BrickletIndustrialAnalogOut.GetConfiguration(out byte voltageRange, out byte currentRange)
Output Parameters:
  • voltageRange – Type: byte, Range: See constants, Default: 1
  • currentRange – Type: byte, Range: See constants, Default: 0

Returns the configuration as set by SetConfiguration().

The following constants are available for this function:

For voltageRange:

  • BrickletIndustrialAnalogOut.VOLTAGE_RANGE_0_TO_5V = 0
  • BrickletIndustrialAnalogOut.VOLTAGE_RANGE_0_TO_10V = 1

For currentRange:

  • BrickletIndustrialAnalogOut.CURRENT_RANGE_4_TO_20MA = 0

Output Parameters:
  • uid – Type: string, Length: up to 8
  • connectedUid – Type: string, Length: up to 8
  • position – Type: char, Range: ['a' to 'h', 'z']
  • hardwareVersion – 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]
  • firmwareVersion – Type: byte[], Length: 3

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an Isolator Bricklet is always at position 'z'.

The device identifier numbers can be found here. There is also a constant for the device identifier of this Bricklet.

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[] BrickletIndustrialAnalogOut.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 BrickletIndustrialAnalogOut.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:

  • BrickletIndustrialAnalogOut.FUNCTION_ENABLE = 1
  • BrickletIndustrialAnalogOut.FUNCTION_DISABLE = 2
  • BrickletIndustrialAnalogOut.FUNCTION_SET_VOLTAGE = 4
  • BrickletIndustrialAnalogOut.FUNCTION_SET_CURRENT = 6
  • BrickletIndustrialAnalogOut.FUNCTION_SET_CONFIGURATION = 8
void BrickletIndustrialAnalogOut.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:

  • BrickletIndustrialAnalogOut.FUNCTION_ENABLE = 1
  • BrickletIndustrialAnalogOut.FUNCTION_DISABLE = 2
  • BrickletIndustrialAnalogOut.FUNCTION_SET_VOLTAGE = 4
  • BrickletIndustrialAnalogOut.FUNCTION_SET_CURRENT = 6
  • BrickletIndustrialAnalogOut.FUNCTION_SET_CONFIGURATION = 8
void BrickletIndustrialAnalogOut.SetResponseExpectedAll(bool responseExpected)
Parameters:
  • responseExpected – Type: bool

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