Class IOLine

Represents a single IO line (digital or analog, input or output) on a Brainboxes Brainboxes.IO.EDDevice. Access IO lines via the Brainboxes.IO.EDDevice.Inputs, Brainboxes.IO.EDDevice.Outputs, or Brainboxes.IO.EDDevice.IOLines collections.

Assembly: Brainboxes.IO.dll​

Declaration
public class IOLine

Properties​

Label​

User definable label for the io line to help when debugging

View Source​
Declaration
public string Label { get; set; }

MostRecentChangeType​

The most recent type of change to occur to the IOLine examples: a. if the previous value seen was 1 and the current value is 0 then the change type will be IOChangeType.FallingEdge. b. if the device has just been turned on then the change type will be IOChangeType.Undefined c. if the line has gone from 1 to 0 and back to 1 within the Brainboxes.IO.EDDevice.IOLineCacheTimeout the change type will be IOChangeType.Latched d. if the line has not changed within the last Brainboxes.IO.EDDevice.IOLineCacheTimeout the change type will be IOChangeType.NoChange

The method will only return meaningful results if there are event handlers attached to the EDDevice

View Source​
Declaration
public IOChangeTypes MostRecentChangeType { get; }

Value​

The current digital state of this IO line. For inputs: HIGH (1) or LOW (0). For outputs/relays: CLOSED (1) or OPEN (0). Only output lines can be set; setting an input throws System.InvalidOperationException.

View Source​
Declaration
public int Value { get; set; }

AValue​

The current analog value of this IO line, in the units determined by the device's Brainboxes.IO.AnalogDataFormat configuration (e.g. volts, milliamps, or temperature). Only analog output lines can be set; setting an analog input throws System.InvalidOperationException.

View Source​
Declaration
public double AValue { get; set; }

Count​

Get the count of the input, that is the number of times the input has latched since the counter has been reset. Use Brainboxes.IO.IOLine.ClearCount() to reset.

View Source​
Declaration
public int Count { get; }

LowLatchedStatus​

Whether this IOLine has had its Low Latch set since the last latch reset

View Source​
Declaration
public bool LowLatchedStatus { get; }

HighLatchedStatus​

Whether this IOLine has had its High Latch set since the last latch reset

View Source​
Declaration
public bool HighLatchedStatus { get; }

Fields​

LogicalNumber​

Toggle()​

If the line is an output this function will invert the state of the line e.g. if the line was closed (1) it will become open (0) or if the line was open (0) it will become closed (1) only valid for Digital outputs

View Source​
Declaration
public int Toggle()
Returns​

System.Int32: The new line Value, 1 or 0

Exceptions​

System.InvalidOperationException
Thrown when the line is not a digital output.

ClearCount()​

Clear the count currently recorded on the line

View Source​
Declaration
public void ClearCount()
Exceptions​

System.InvalidOperationException
Thrown when the line is an output.
