Gets / Sets the .NET Type of the PLC value

[Visual Basic]
NotOverridable Public Property NetType As Type _
    Implements ITag.NetType
[C#]
public System.Type NetType {get; set;}

Implements

ITag.NetType

Remarks

Setting this property will set the DataType property as follows:

System.Boolean = ATOMIC.BOOL
System.SByte = ATOMIC.SINT
System.Byte = ATOMIC.SINT
System.Int16 = ATOMIC.INT
System.UInt16 = ATOMIC.INT
System.Int32 = ATOMIC.DINT
System.UInt32 = ATOMIC.DINT
System.Single = ATOMIC.REAL
System.Double = ATOMIC.REAL

System.String = ATOMIC.STRING

System.Int64 = ATOMIC.LINT

System.Object = ATOMIC.OBJECT

 

Exceptions

Exception Type Condition
ArgumentException Thrown if invalid Type is set.
