API¶

Since Visual Basic .NET does not support multiple return values directly, we use the ByRef keyword to return multiple values from a function.

All functions and procedures listed below are thread-safe.

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.

Callback Configuration Functions¶

Sub BrickletIndustrialCounter.SetAllCounterCallbackConfiguration(ByVal period As Long, ByVal valueHasToChange As Boolean)¶

Parameters:	period – Type: Long, Unit: 1 ms, Range: [0 to 2³² - 1], Default: 0 valueHasToChange – Type: Boolean, Default: false

The period is the period with which the AllCounterCallback 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.

Sub BrickletIndustrialCounter.GetAllCounterCallbackConfiguration(ByRef period As Long, ByRef valueHasToChange As Boolean)¶

Output Parameters:	period – Type: Long, Unit: 1 ms, Range: [0 to 2³² - 1], Default: 0 valueHasToChange – Type: Boolean, Default: false

Returns the callback configuration as set by SetAllCounterCallbackConfiguration().

Sub BrickletIndustrialCounter.SetAllSignalDataCallbackConfiguration(ByVal period As Long, ByVal valueHasToChange As Boolean)¶

Parameters:	period – Type: Long, Unit: 1 ms, Range: [0 to 2³² - 1], Default: 0 valueHasToChange – Type: Boolean, Default: false

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

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

Sub BrickletIndustrialCounter.GetAllSignalDataCallbackConfiguration(ByRef period As Long, ByRef valueHasToChange As Boolean)¶

Output Parameters:	period – Type: Long, Unit: 1 ms, Range: [0 to 2³² - 1], Default: 0 valueHasToChange – Type: Boolean, Default: false

Returns the callback configuration as set by SetAllSignalDataCallbackConfiguration().

Callbacks¶

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

Sub MyCallback(ByVal sender As BrickletIndustrialCounter, ByVal value As Short)
    Console.WriteLine("Value: {0}", value)
End Sub

AddHandler industrialCounter.ExampleCallback, AddressOf MyCallback

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 BrickletIndustrialCounter.AllCounterCallback(ByVal sender As BrickletIndustrialCounter, ByVal counter() As Long)¶

Callback Parameters:	sender – Type: BrickletIndustrialCounter counter – Type: Long Array, Length: 4, Range: [-2⁴⁷ to 2⁴⁷ - 1]

This callback is triggered periodically according to the configuration set by SetAllCounterCallbackConfiguration().

The parameters are the same as GetAllCounter().

Event BrickletIndustrialCounter.AllSignalDataCallback(ByVal sender As BrickletIndustrialCounter, ByVal dutyCycle() As Integer, ByVal period() As Long, ByVal frequency() As Long, ByVal value() As Boolean)¶

Callback Parameters:	sender – Type: BrickletIndustrialCounter dutyCycle – Type: Integer Array, Length: 4, Unit: 1/100 %, Range: [0 to 10000] period – Type: Long Array, Length: 4, Unit: 1 ns, Range: [0 to 2⁶⁴ - 1] frequency – Type: Long Array, Length: 4, Unit: 1/1000 Hz, Range: [0 to 2³² - 1] value – Type: Boolean Array, Length: 4

This callback is triggered periodically according to the configuration set by SetAllSignalDataCallbackConfiguration().

The parameters are the same as GetAllSignalData().

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.

Function BrickletIndustrialCounter.GetAPIVersion() As Byte()¶

Output Parameters:	apiVersion – Type: Byte Array, 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.

Function BrickletIndustrialCounter.GetResponseExpected(ByVal functionId As Byte) As Boolean¶

Parameters:	functionId – Type: Byte, Range: See constants
Returns:	responseExpected – Type: Boolean

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:

BrickletIndustrialCounter.FUNCTION_SET_COUNTER = 3
BrickletIndustrialCounter.FUNCTION_SET_ALL_COUNTER = 4

Sub BrickletIndustrialCounter.SetResponseExpectedAll(ByVal responseExpected As Boolean)¶

Parameters:	responseExpected – Type: Boolean

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

Internal Functions¶

Internal functions are used for maintenance tasks such as flashing a new firmware of changing the UID of a Bricklet. These task should be performed using Brick Viewer instead of using the internal functions directly.

Function BrickletIndustrialCounter.SetBootloaderMode(ByVal mode As Byte) As Byte¶

Parameters:	mode – Type: Byte, Range: See constants
Returns:	status – Type: Byte, Range: See constants

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.

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

The following constants are available for this function:

For mode:

BrickletIndustrialCounter.BOOTLOADER_MODE_BOOTLOADER = 0
BrickletIndustrialCounter.BOOTLOADER_MODE_FIRMWARE = 1
BrickletIndustrialCounter.BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2
BrickletIndustrialCounter.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
BrickletIndustrialCounter.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4

For status:

BrickletIndustrialCounter.BOOTLOADER_STATUS_OK = 0
BrickletIndustrialCounter.BOOTLOADER_STATUS_INVALID_MODE = 1
BrickletIndustrialCounter.BOOTLOADER_STATUS_NO_CHANGE = 2
BrickletIndustrialCounter.BOOTLOADER_STATUS_ENTRY_FUNCTION_NOT_PRESENT = 3
BrickletIndustrialCounter.BOOTLOADER_STATUS_DEVICE_IDENTIFIER_INCORRECT = 4
BrickletIndustrialCounter.BOOTLOADER_STATUS_CRC_MISMATCH = 5

Function BrickletIndustrialCounter.GetBootloaderMode() As Byte¶

Returns:	mode – Type: Byte, Range: See constants

Returns the current bootloader mode, see SetBootloaderMode().

The following constants are available for this function:

For mode:

BrickletIndustrialCounter.BOOTLOADER_MODE_BOOTLOADER = 0
BrickletIndustrialCounter.BOOTLOADER_MODE_FIRMWARE = 1
BrickletIndustrialCounter.BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2
BrickletIndustrialCounter.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
BrickletIndustrialCounter.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4

Sub BrickletIndustrialCounter.SetWriteFirmwarePointer(ByVal pointer As Long)¶

Parameters:	pointer – Type: Long, Unit: 1 B, Range: [0 to 2³² - 1]

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.

Function BrickletIndustrialCounter.WriteFirmware(ByVal data() As Byte) As Byte¶

Parameters:	data – Type: Byte Array, Length: 64, Range: [0 to 255]
Returns:	status – Type: Byte, Range: [0 to 255]

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.

Sub BrickletIndustrialCounter.WriteUID(ByVal uid As Long)¶

Parameters:	uid – Type: Long, Range: [0 to 2³² - 1]

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.

Function BrickletIndustrialCounter.ReadUID() As Long¶

Returns:	uid – Type: Long, Range: [0 to 2³² - 1]

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

Constants¶

Const BrickletIndustrialCounter.DEVICE_IDENTIFIER¶

This constant is used to identify a Industrial Counter 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.

Const BrickletIndustrialCounter.DEVICE_DISPLAY_NAME¶: This constant represents the human readable name of a Industrial Counter Bricklet.
