API¶

Most functions of the C/C++ bindings return an error code (e_code). Data returned from the device, when a getter is called, is handled via output parameters. These parameters are labeled with the ret_ prefix.

Possible error codes are:

E_OK = 0
E_TIMEOUT = -1
E_NO_STREAM_SOCKET = -2
E_HOSTNAME_INVALID = -3
E_NO_CONNECT = -4
E_NO_THREAD = -5
E_NOT_ADDED = -6 (unused since C/C++ bindings version 2.0.0)
E_ALREADY_CONNECTED = -7
E_NOT_CONNECTED = -8
E_INVALID_PARAMETER = -9
E_NOT_SUPPORTED = -10
E_UNKNOWN_ERROR_CODE = -11
E_STREAM_OUT_OF_SYNC = -12
E_INVALID_UID = -13
E_NON_ASCII_CHAR_IN_SECRET = -14
E_WRONG_DEVICE_TYPE = -15
E_DEVICE_REPLACED = -16
E_WRONG_RESPONSE_LENGTH = -17

as defined in ip_connection.h.

All functions listed below are thread-safe.

Returns:	e_code – Type: int

You can turn the Out LED off, on or show a heartbeat. You can also set the LED to "Out 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 output value (voltage or current).

You can configure the channel status behavior with industrial_analog_out_v2_set_out_led_status_config().

For config:

INDUSTRIAL_ANALOG_OUT_V2_OUT_LED_CONFIG_OFF = 0
INDUSTRIAL_ANALOG_OUT_V2_OUT_LED_CONFIG_ON = 1

Output Parameters:	ret_config – Type: uint8_t, Range: See constants, Default: 3
Returns:	e_code – Type: int

Returns the Out LED configuration as set by industrial_analog_out_v2_set_out_led_config()

The following constants are available for this function:

Returns:	e_code – Type: int

Sets the Out LED status config. This config is used if the Out LED is configured as "Out Status", see industrial_analog_out_v2_set_out_led_config().

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 mV or µA above which the LED should turn on and set the "max" parameter to 0. Example: If you set a positive threshold of 5V, the LED will turn on as soon as the output value exceeds 5V and turn off again if it goes below 5V. For a negative threshold set the "max" parameter to the threshold value in mV or µA below which the LED should turn on and set the "min" parameter to 0. Example: If you set a negative threshold of 5V, the LED will turn on as soon as the output value goes below 5V and the LED will turn off when the output value exceeds 5V.

In intensity mode you can define a range mV or µA that is used to scale the brightness of the LED. Example with min=2V, max=8V: The LED is off at 2V and below, on at 8V and above and the brightness is linearly scaled between the values 2V and 8V. If the min value is greater than the max value, the LED brightness is scaled the other way around.

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.

int industrial_analog_out_v2_get_api_version(IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t ret_api_version[3])¶

int industrial_analog_out_v2_get_response_expected(IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t function_id, bool *ret_response_expected)¶

Parameters:	industrial_analog_out_v2 – Type: IndustrialAnalogOutV2 * function_id – Type: uint8_t, Range: See constants
Output Parameters:	ret_response_expected – Type: bool
Returns:	e_code – Type: int

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 industrial_analog_out_v2_set_response_expected(). 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 function_id:

INDUSTRIAL_ANALOG_OUT_V2_FUNCTION_SET_ENABLED = 1
INDUSTRIAL_ANALOG_OUT_V2_FUNCTION_SET_VOLTAGE = 3

Returns:	e_code – Type: int

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.

Returns:	e_code – Type: int

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.

int industrial_analog_out_v2_set_bootloader_mode(IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t mode, uint8_t *ret_status)¶

Parameters:	industrial_analog_out_v2 – Type: IndustrialAnalogOutV2 * mode – Type: uint8_t, Range: See constants
Output Parameters:	ret_status – Type: uint8_t, Range: See constants
Returns:	e_code – Type: int

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.

Sets the firmware pointer for industrial_analog_out_v2_write_firmware(). 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.

int industrial_analog_out_v2_write_firmware(IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t data[64], uint8_t *ret_status)¶

Parameters:	industrial_analog_out_v2 – Type: IndustrialAnalogOutV2 * data – Type: uint8_t[64], Range: [0 to 255]
Output Parameters:	ret_status – Type: uint8_t, Range: [0 to 255]
Returns:	e_code – Type: int

Writes 64 Bytes of firmware at the position as written by industrial_analog_out_v2_set_write_firmware_pointer() 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.

int industrial_analog_out_v2_write_uid(IndustrialAnalogOutV2 *industrial_analog_out_v2, uint32_t uid)¶

Parameters:	industrial_analog_out_v2 – Type: IndustrialAnalogOutV2 * uid – Type: uint32_t, Range: [0 to 2³² - 1]
Returns:	e_code – Type: int

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.

int industrial_analog_out_v2_read_uid(IndustrialAnalogOutV2 *industrial_analog_out_v2, uint32_t *ret_uid)¶

Parameters:	industrial_analog_out_v2 – Type: IndustrialAnalogOutV2 *
Output Parameters:	ret_uid – Type: uint32_t, Range: [0 to 2³² - 1]
Returns:	e_code – Type: int

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

Constants¶

INDUSTRIAL_ANALOG_OUT_V2_DEVICE_IDENTIFIER¶

This constant is used to identify a Industrial Analog Out Bricklet 2.0.

The industrial_analog_out_v2_get_identity() function and the IPCON_CALLBACK_ENUMERATE callback of the IP Connection have a device_identifier parameter to specify the Brick's or Bricklet's type.

INDUSTRIAL_ANALOG_OUT_V2_DEVICE_DISPLAY_NAME¶: This constant represents the human readable name of a Industrial Analog Out Bricklet 2.0.
