Constructor & Destructor Documentation

RS422()

VIB_NET::RS422::RS422

(

)

Default constructor for the device object

The device must be opened with Open() before it can be used.

Member Function Documentation

GetBit()

Boolean VIB_NET::RS422::GetBit

(

UInt32

BitIndex

)

Reads the state of one input.

Parameters

BitIndex

Input signal index, 0 ... (NumberOfInputs - 1)

Returns

State of the input

Example:

C#: Rs422_Example.cs
Visual Basic: Rs422_Example.vb

Reset()

void VIB_NET::RS422::Reset

(

)

Resets the device to default settings.

See also VIB::Rs422::Reset().

SetBit()

void VIB_NET::RS422::SetBit	(	UInt32	BitIndex,
		Boolean	OnOff
	)

Sets the state of one output.

Parameters

BitIndex	Output signal index, 0 ... (NumberOfOutputs - 1)
OnOff	Output value: on or off

Example:

C#: Rs422_Example.cs
Visual Basic: Rs422_Example.vb

SetSource()

void VIB_NET::RS422::SetSource	(	UInt32	BitIndex,
		RS422::eOUT_SOURCE	Source,
		bool	InvertOutput
	)

Sets the source for an output signal.

For setting the output value manually with Output or SetBit(), the source eOUT_SOURCE::REGISTER has to be selected (default).

Note

The VisionBox AGE-X1 doesn't have a Multiplexer and therefore doesn't support this function

Parameters

BitIndex	Output signal index, 0 ... (NumberOfOutputs - 1)
Source	source for the line
InvertOutput	true = invert line

Property Documentation

Input

VIB_NET::RS422::Input

get

Reads the state of the input signals.

The value is the binary representation of the signals, LSB is BIT0.

Example:

C#: Rs422_Example.cs
Visual Basic: Rs422_Example.vb

NumberOfInputs

VIB_NET::RS422::NumberOfInputs

get

Contains the number of input signals.

NumberOfOutputs

VIB_NET::RS422::NumberOfOutputs

get

Contains the number of output signals.

Output

VIB_NET::RS422::Output

set

Sets the state of the output signals.

Parameters

Val

Bits 0..15: Binary representation of outputs. The actual number of available outputs is hardware dependent. Bits 16..31: Mask bits can be used to change only certain outputs. This is particularly useful to control certain outputs by different threads. If the upper 16 bits of Val are set to zero, all outputs will be set.

Example:

C#: Rs422_Example.cs
Visual Basic: Rs422_Example.vb

Example:

//change BIT0 & BIT1 to on, all other to off
pRS422.Output = (0x3)
 
//turn BIT1 off, BIT0 stays on
pRS422.Output = ((1<<(16+1)) | 0x00)

Type

VIB_NET::RS422::Type

get

Returns the device type for the current instance, see eDEVICE_TYPE
