Modbus - Industrial Analog Out Bricklet¶

Basic Functions¶

BrickletIndustrialAnalogOut.enable¶

Function ID:	1
Request:	empty payload
Response:	no response

Enables the output of voltage and current.

The default is disabled.

BrickletIndustrialAnalogOut.disable¶

Function ID:	2
Request:	empty payload
Response:	no response

Disables the output of voltage and current.

The default is disabled.

BrickletIndustrialAnalogOut.is_enabled¶

Function ID:	3
Request:	empty payload
Response:	enabled – Type: bool, Default: false

Returns true if output of voltage and current is enabled, false otherwise.

BrickletIndustrialAnalogOut.set_voltage¶

Function ID:	4
Request:	voltage – Type: uint16, Unit: 1 mV, Range: [0 to 10000]
Response:	no response

Sets the output voltage.

The output voltage and output current are linked. Changing the output voltage also changes the output current.

BrickletIndustrialAnalogOut.get_voltage¶

Function ID:	5
Request:	empty payload
Response:	voltage – Type: uint16, Unit: 1 mV, Range: [0 to 10000]

Returns the voltage as set by set_voltage.

BrickletIndustrialAnalogOut.set_current¶

Function ID:	6
Request:	current – Type: uint16, Unit: 1 µA, Range: [0 to 24000]
Response:	no response

Sets the output current.

The output current and output voltage are linked. Changing the output current also changes the output voltage.

BrickletIndustrialAnalogOut.get_current¶

Function ID:	7
Request:	empty payload
Response:	current – Type: uint16, Unit: 1 µA, Range: [0 to 24000]

Returns the current as set by set_current.

Advanced Functions¶

BrickletIndustrialAnalogOut.set_configuration¶

Function ID:	8
Request:	voltage_range – Type: uint8, Range: See meanings, Default: 1 current_range – Type: uint8, Range: See meanings, Default: 0
Response:	no response

Configures the voltage and current range.

Possible voltage ranges are:

• 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 meanings are defined for the elements of this function:

For voltage_range:

• 0 = 0 To 5V
• 1 = 0 To 10V

For current_range:

• 0 = 4 To 20mA
• 1 = 0 To 20mA
• 2 = 0 To 24mA

BrickletIndustrialAnalogOut.get_configuration¶

Function ID:	9
Request:	empty payload
Response:	voltage_range – Type: uint8, Range: See meanings, Default: 1 current_range – Type: uint8, Range: See meanings, Default: 0

Returns the configuration as set by set_configuration.

The following meanings are defined for the elements of this function:

For voltage_range:

• 0 = 0 To 5V
• 1 = 0 To 10V

For current_range:

• 0 = 4 To 20mA
• 1 = 0 To 20mA
• 2 = 0 To 24mA

BrickletIndustrialAnalogOut.get_identity¶

Function ID:	255
Request:	empty payload
Response:	uid – Type: char[8] connected_uid – Type: char[8] position – Type: char, Range: ['a' to 'h', 'z'] hardware_version – Type: uint8[3] 0: major – Type: uint8, Range: [0 to 255] 1: minor – Type: uint8, Range: [0 to 255] 2: revision – Type: uint8, Range: [0 to 255] firmware_version – Type: uint8[3] 0: major – Type: uint8, Range: [0 to 255] 1: minor – Type: uint8, Range: [0 to 255] 2: revision – Type: uint8, Range: [0 to 255] device_identifier – Type: uint16, Range: [0 to 216 - 1]

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', '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.
