API

Generally, every method of the Mathematica 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 .NET/Link does not support multiple return values directly, we use the out keyword to return multiple values from a method. For further information about the out keyword in .NET/Link see the corresponding Mathematica .NET/Link documentation.

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

Basic Functions

BrickletIndustrialDual020mAV2[uid, ipcon] → industrialDual020mAV2
Parameters:
  • uid -- String
  • ipcon -- NETObject[IPConnection]
Returns:
  • industrialDual020mAV2 -- NETObject[BrickletIndustrialDual020mAV2]

Creates an object with the unique device ID uid:

industrialDual020mAV2=NETNew["Tinkerforge.BrickletIndustrialDual020mAV2","YOUR_DEVICE_UID",ipcon]

This object can then be used after the IP Connection is connected (see examples above).

The .NET runtime has built-in garbage collection that frees objects that are no longer in use by a program. But because Mathematica can not automatically tell when a Mathematica "program" doesn't use a .NET object anymore, this has to be done by the program. For this the ReleaseNETObject[] function is used in the examples.

For further information about object management in .NET/Link see the corresponding Mathematica .NET/Link documentation.

BrickletIndustrialDual020mAV2@GetCurrent[channel] → current
Parameters:
  • channel -- Integer
Returns:
  • current -- Integer

Returns the current of the specified channel. The value is in nA and between 0nA and 22505322nA (22.5mA).

It is possible to detect if an IEC 60381-1 compatible sensor is connected and if it works probably.

If the returned current is below 4mA, there is likely no sensor connected or the connected sensor is defective. If the returned current is over 20mA, there might be a short circuit or the sensor is defective.

If you want to get the value periodically, it is recommended to use the CurrentCallback callback. You can set the callback configuration with SetCurrentCallbackConfiguration[].

BrickletIndustrialDual020mAV2@SetChannelLEDConfig[channel, config] → Null
Parameters:
  • channel -- Integer
  • config -- Integer

Each channel has a corresponding LED. You can turn the LED off, on or show a heartbeat. You can also set the LED to "Channel Status". In this mode the LED can either be turned on with a pre-defined threshold or the intensity of the LED can change with the measured value.

You can configure the channel status behavior with SetChannelLEDStatusConfig[].

By default all channel LEDs are configured as "Channel Status".

The following constants are available for this function:

  • BrickletIndustrialDual020mAV2`CHANNELULEDUCONFIGUOFF = 0
  • BrickletIndustrialDual020mAV2`CHANNELULEDUCONFIGUON = 1
  • BrickletIndustrialDual020mAV2`CHANNELULEDUCONFIGUSHOWUHEARTBEAT = 2
  • BrickletIndustrialDual020mAV2`CHANNELULEDUCONFIGUSHOWUCHANNELUSTATUS = 3
BrickletIndustrialDual020mAV2@GetChannelLEDConfig[channel] → config
Parameters:
  • channel -- Integer
Returns:
  • config -- Integer

Returns the channel LED configuration as set by SetChannelLEDConfig[]

The following constants are available for this function:

  • BrickletIndustrialDual020mAV2`CHANNELULEDUCONFIGUOFF = 0
  • BrickletIndustrialDual020mAV2`CHANNELULEDUCONFIGUON = 1
  • BrickletIndustrialDual020mAV2`CHANNELULEDUCONFIGUSHOWUHEARTBEAT = 2
  • BrickletIndustrialDual020mAV2`CHANNELULEDUCONFIGUSHOWUCHANNELUSTATUS = 3
BrickletIndustrialDual020mAV2@SetChannelLEDStatusConfig[channel, min, max, config] → Null
Parameters:
  • channel -- Integer
  • min -- Integer
  • max -- Integer
  • config -- Integer

Sets the channel LED status config. This config is used if the channel LED is configured as "Channel Status", see SetChannelLEDConfig[].

For each channel you can choose between threshold and intensity mode.

In threshold mode you can define a positive or a negative threshold. For a positive threshold set the "min" parameter to the threshold value in nA above which the LED should turn on and set the "max" parameter to 0. Example: If you set a positive threshold of 10mA, the LED will turn on as soon as the current exceeds 10mA and turn off again if it goes below 10mA. For a negative threshold set the "max" parameter to the threshold value in nA below which the LED should turn on and set the "min" parameter to 0. Example: If you set a negative threshold of 10mA, the LED will turn on as soon as the current goes below 10mA and the LED will turn off when the current exceeds 10mA.

In intensity mode you can define a range in nA that is used to scale the brightness of the LED. Example with min=4mA and max=20mA: The LED is off at 4mA and below, on at 20mA and above and the brightness is linearly scaled between the values 4mA and 20mA. If the min value is greater than the max value, the LED brightness is scaled the other way around.

By default the channel LED status config is set to intensity with min=4mA and max=20mA.

BrickletIndustrialDual020mAV2@GetAPIVersion[] → {apiVersion1, apiVersion2, apiVersion3}
Returns:
  • apiVersioni -- Integer

Returns the version of the API definition (major, minor, revision) 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.

BrickletIndustrialDual020mAV2@GetResponseExpected[functionId] → responseExpected
Parameters:
  • functionId -- Integer
Returns:
  • responseExpected -- True/False

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 send and errors are silently ignored, because they cannot be detected.

See SetResponseExpected[] for the list of function ID constants available for this function.

BrickletIndustrialDual020mAV2@SetResponseExpected[functionId, responseExpected] → Null
Parameters:
  • functionId -- Integer
  • responseExpected -- True/False

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 send and errors are silently ignored, because they cannot be detected.

The following function ID constants are available for this function:

  • BrickletIndustrialDual020mAV2`FUNCTIONUSETUCURRENTUCALLBACKUCONFIGURATION = 2

The errors counts are for errors that occur on the Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.

BrickletIndustrialDual020mAV2@SetBootloaderMode[mode] → status
Parameters:
  • mode -- Integer
Returns:
  • status -- Integer

Sets the bootloader mode and returns the status after the requested mode change was instigated.

You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.

BrickletIndustrialDual020mAV2@SetWriteFirmwarePointer[pointer] → Null
Parameters:
  • pointer -- Integer

Sets the firmware pointer for WriteFirmware[]. The pointer has to be increased by chunks of size 64. The data is written to flash every 4 chunks (which equals to one page of size 256).

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

BrickletIndustrialDual020mAV2@WriteFirmware[{data1, data2, ..., data64}] → status
Parameters:
  • datai -- Integer
Returns:
  • status -- Integer

Writes 64 Bytes of firmware at the position as written by SetWriteFirmwarePointer[] before. The firmware is written to flash every 4 chunks.

You can only write firmware in bootloader mode.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

BrickletIndustrialDual020mAV2@SetStatusLEDConfig[config] → Null
Parameters:
  • config -- Integer

Sets the status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets.

You can also turn the LED permanently on/off or show a heartbeat.

If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.

The following constants are available for this function:

BrickletIndustrialDual020mAV2@GetChipTemperature[] → temperature
Returns:
  • temperature -- Integer

Returns the temperature in °C as measured inside the microcontroller. The value returned is not the ambient temperature!

The temperature is only proportional to the real temperature and it has bad accuracy. Practically it is only useful as an indicator for temperature changes.

BrickletIndustrialDual020mAV2@Reset[] → Null

Calling this function will reset the Bricklet. All configurations will be lost.

After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!

BrickletIndustrialDual020mAV2@WriteUID[uid] → Null
Parameters:
  • uid -- Integer

Writes a new UID into flash. If you want to set a new UID you have to decode the Base58 encoded UID string into an integer first.

We recommend that you use Brick Viewer to change the UID.

BrickletIndustrialDual020mAV2@ReadUID[] → uid
Returns:
  • uid -- Integer

Returns the current UID as an integer. Encode as Base58 to get the usual string version.

BrickletIndustrialDual020mAV2@GetIdentity[out uid, out connectedUid, out position, out {hardwareVersion1, hardwareVersion2, hardwareVersion3}, out {firmwareVersion1, firmwareVersion2, firmwareVersion3}, out deviceIdentifier] → Null
Parameters:
  • uid -- String
  • connectedUid -- String
  • position -- Integer
  • hardwareVersioni -- Integer
  • firmwareVersioni -- Integer
  • deviceIdentifier -- Integer

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be 'a', 'b', 'c' or 'd'.

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

Callback Configuration Functions

BrickletIndustrialDual020mAV2@SetCurrentCallbackConfiguration[channel, period, valueHasToChange, option, min, max] → Null
Parameters:
  • channel -- Integer
  • period -- Integer
  • valueHasToChange -- True/False
  • option -- Integer
  • min -- Integer
  • max -- Integer

The period in ms is the period with which the CurrentCallback callback is triggered periodically. A value of 0 turns the callback off.

If the value has to change-parameter is set to true, the callback is only triggered after the value has changed. If the value didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

It is furthermore possible to constrain the callback with thresholds.

The option-parameter together with min/max sets a threshold for the CurrentCallback callback.

The following options are possible:

Option Description
'x' Threshold is turned off
'o' Threshold is triggered when the value is outside the min and max values
'i' Threshold is triggered when the value is inside or equal to the min and max values
'<' Threshold is triggered when the value is smaller than the min value (max is ignored)
'>' Threshold is triggered when the value is greater than the min value (max is ignored)

If the option is set to 'x' (threshold turned off) the callback is triggered with the fixed period.

The default value is (0, false, 'x', 0, 0).

The following constants are available for this function:

  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUOFF = ToCharacterCode["x"][[0]]
  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUOUTSIDE = ToCharacterCode["o"][[0]]
  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUINSIDE = ToCharacterCode["i"][[0]]
  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUSMALLER = ToCharacterCode["<"][[0]]
  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUGREATER = ToCharacterCode[">"][[0]]
BrickletIndustrialDual020mAV2@GetCurrentCallbackConfiguration[channel, out period, out valueHasToChange, out option, out min, out max] → Null
Parameters:
  • channel -- Integer
  • period -- Integer
  • valueHasToChange -- True/False
  • option -- Integer
  • min -- Integer
  • max -- Integer

Returns the callback configuration as set by SetCurrentCallbackConfiguration[].

The following constants are available for this function:

  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUOFF = ToCharacterCode["x"][[0]]
  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUOUTSIDE = ToCharacterCode["o"][[0]]
  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUINSIDE = ToCharacterCode["i"][[0]]
  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUSMALLER = ToCharacterCode["<"][[0]]
  • BrickletIndustrialDual020mAV2`THRESHOLDUOPTIONUGREATER = ToCharacterCode[">"][[0]]

Callbacks

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done by assigning a function to a callback property of the device object:

MyCallback[sender_,value_]:=Print["Value: "<>ToString[value]]

AddEventHandler[industrialDual020mAV2@ExampleCallback,MyCallback]

For further information about event handling using .NET/Link see the corresponding Mathematica .NET/Link documentation.

The available callback property and their type of parameters are described below.

Note

Using callbacks for recurring events is always preferred compared to using getters. It will use less USB bandwidth and the latency will be a lot better, since there is no round trip time.

event BrickletIndustrialDual020mAV2@CurrentCallback[sender, channel, current]
Parameters:
  • sender -- NETObject[BrickletIndustrialDual020mAV2]
  • channel -- Integer
  • current -- Integer

This callback is triggered periodically according to the configuration set by SetCurrentCallbackConfiguration[].

The parameter is the same as GetCurrent[].

Constants

BrickletIndustrialDual020mAV2`DEVICEUIDENTIFIER

This constant is used to identify a Industrial Dual 0-20mA Bricklet 2.0.

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

BrickletIndustrialDual020mAV2`DEVICEDISPLAYNAME

This constant represents the human readable name of a Industrial Dual 0-20mA Bricklet 2.0.
