Basic Functions¶

class BrickletIndustrialDigitalOut4(string uid, IPConnection ipcon)¶

Parameters:	uid – Type: string ipcon – Type: IPConnection
Returns:	industrialDigitalOut4 – Type: BrickletIndustrialDigitalOut4

Creates an object with the unique device ID uid:

BrickletIndustrialDigitalOut4 industrialDigitalOut4 = new BrickletIndustrialDigitalOut4("YOUR_DEVICE_UID", ipcon);

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

void BrickletIndustrialDigitalOut4.SetValue(int valueMask)¶

Parameters:	valueMask – Type: int, Range: [0 to 216 - 1]

Sets the output value with a bitmask (16bit). A 1 in the bitmask means high and a 0 in the bitmask means low.

For example: The value 3 or 0b0011 will turn pins 0-1 high and the other pins low.

If no groups are used (see SetGroup()), the pins correspond to the markings on the Industrial Digital Out 4 Bricklet.

If groups are used, the pins correspond to the element in the group. Element 1 in the group will get pins 0-3, element 2 pins 4-7, element 3 pins 8-11 and element 4 pins 12-15.

All running monoflop timers will be aborted if this function is called.

int BrickletIndustrialDigitalOut4.GetValue()¶

Returns:	valueMask – Type: int, Range: [0 to 216 - 1]

Returns the bitmask as set by SetValue().

void BrickletIndustrialDigitalOut4.SetSelectedValues(int selectionMask, int valueMask)¶

Parameters:	selectionMask – Type: int, Range: [0 to 216 - 1] valueMask – Type: int, Range: [0 to 216 - 1]

Sets the output value with a bitmask, according to the selection mask. The bitmask is 16 bit long, true refers to high and false refers to low.

For example: The values (3, 1) or (0b0011, 0b0001) will turn pin 0 high, pin 1 low the other pins remain untouched.

If no groups are used (see SetGroup()), the pins correspond to the markings on the Industrial Digital Out 4 Bricklet.

If groups are used, the pins correspond to the element in the group. Element 1 in the group will get pins 0-3, element 2 pins 4-7, element 3 pins 8-11 and element 4 pins 12-15.

Running monoflop timers for the selected pins will be aborted if this function is called.

Advanced Functions¶

void BrickletIndustrialDigitalOut4.SetMonoflop(int selectionMask, int valueMask, long time)¶

Parameters:	selectionMask – Type: int, Range: [0 to 216 - 1] valueMask – Type: int, Range: [0 to 216 - 1] time – Type: long, Unit: 1 ms, Range: [0 to 232 - 1]

Configures a monoflop of the pins specified by the first parameter bitmask.

The second parameter is a bitmask with the desired value of the specified pins. A 1 in the bitmask means high and a 0 in the bitmask means low.

The third parameter indicates the time that the pins should hold the value.

If this function is called with the parameters (9, 1, 1500) or (0b1001, 0b0001, 1500): Pin 0 will get high and pin 3 will get low. In 1.5s pin 0 will get low and pin 3 will get high again.

A monoflop can be used as a fail-safe mechanism. For example: Lets assume you have a RS485 bus and a Digital Out 4 Bricklet connected to one of the slave stacks. You can now call this function every second, with a time parameter of two seconds and pin 0 high. Pin 0 will be high all the time. If now the RS485 connection is lost, then pin 0 will turn low in at most two seconds.

void BrickletIndustrialDigitalOut4.GetMonoflop(byte pin, out int value, out long time, out long timeRemaining)¶

Parameters:	pin – Type: byte, Range: [0 to 15]
Output Parameters:	value – Type: int, Range: [0 to 1] time – Type: long, Unit: 1 ms, Range: [0 to 232 - 1] timeRemaining – Type: long, Unit: 1 ms, Range: [0 to 232 - 1]

Returns (for the given pin) the current value and the time as set by SetMonoflop() as well as the remaining time until the value flips.

If the timer is not running currently, the remaining time will be returned as 0.

void BrickletIndustrialDigitalOut4.SetGroup(char[] group)¶

Parameters:	group – Type: char[], Length: 4, Range: ['a' to 'd', 'n']

Sets a group of Digital Out 4 Bricklets that should work together. You can find Bricklets that can be grouped together with GetAvailableForGroup().

The group consists of 4 elements. Element 1 in the group will get pins 0-3, element 2 pins 4-7, element 3 pins 8-11 and element 4 pins 12-15.

Each element can either be one of the ports ('a' to 'd') or 'n' if it should not be used.

For example: If you have two Digital Out 4 Bricklets connected to port A and port B respectively, you could call with ['a', 'b', 'n', 'n'].

Now the pins on the Digital Out 4 on port A are assigned to 0-3 and the pins on the Digital Out 4 on port B are assigned to 4-7. It is now possible to call SetValue() and control two Bricklets at the same time.

char[] BrickletIndustrialDigitalOut4.GetGroup()¶

Returns:	group – Type: char[], Length: 4, Range: ['a' to 'd', 'n']

Returns the group as set by SetGroup()

byte BrickletIndustrialDigitalOut4.GetAvailableForGroup()¶

Returns:	available – Type: byte, Range: [0 to 15]

Returns a bitmask of ports that are available for grouping. For example the value 5 or 0b0101 means: Port A and port C are connected to Bricklets that can be grouped together.

void BrickletIndustrialDigitalOut4.GetIdentity(out string uid, out string connectedUid, out char position, out byte[] hardwareVersion, out byte[] firmwareVersion, out int deviceIdentifier)¶

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 0: major – Type: byte, Range: [0 to 255] 1: minor – Type: byte, Range: [0 to 255] 2: revision – Type: byte, Range: [0 to 255] deviceIdentifier – Type: int, 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. There is also a constant for the device identifier of this Bricklet.

Callbacks¶

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done by appending your callback handler to the corresponding event:

void MyCallback(BrickletIndustrialDigitalOut4 sender, int value)
{
    System.Console.WriteLine("Value: " + value);
}

industrialDigitalOut4.ExampleCallback += MyCallback;

The available events are described below.

event BrickletIndustrialDigitalOut4.MonoflopDoneCallback(BrickletIndustrialDigitalOut4 sender, int selectionMask, int valueMask)¶

Callback Parameters:	sender – Type: BrickletIndustrialDigitalOut4 selectionMask – Type: int, Range: [0 to 216 - 1] valueMask – Type: int, Range: [0 to 216 - 1]

This callback is triggered whenever a monoflop timer reaches 0. The parameters contain the involved pins and the current value of the pins (the value after the monoflop).

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[] BrickletIndustrialDigitalOut4.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 BrickletIndustrialDigitalOut4.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:

• BrickletIndustrialDigitalOut4.FUNCTION_SET_VALUE = 1
• BrickletIndustrialDigitalOut4.FUNCTION_SET_MONOFLOP = 3
• BrickletIndustrialDigitalOut4.FUNCTION_SET_GROUP = 5
• BrickletIndustrialDigitalOut4.FUNCTION_SET_SELECTED_VALUES = 9

void BrickletIndustrialDigitalOut4.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:

• BrickletIndustrialDigitalOut4.FUNCTION_SET_VALUE = 1
• BrickletIndustrialDigitalOut4.FUNCTION_SET_MONOFLOP = 3
• BrickletIndustrialDigitalOut4.FUNCTION_SET_GROUP = 5
• BrickletIndustrialDigitalOut4.FUNCTION_SET_SELECTED_VALUES = 9

void BrickletIndustrialDigitalOut4.SetResponseExpectedAll(bool responseExpected)¶

Parameters:	responseExpected – Type: bool

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

Constants¶

int BrickletIndustrialDigitalOut4.DEVICE_IDENTIFIER¶

This constant is used to identify a Industrial Digital Out 4 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.

string BrickletIndustrialDigitalOut4.DEVICE_DISPLAY_NAME¶

This constant represents the human readable name of a Industrial Digital Out 4 Bricklet.
