Properties

ReadValueRangePropertyValueCallback

Gets or sets a callback used to read the value range property value.

C# 

public OpcReadValueRangePropertyValueCallback ReadValueRangePropertyValueCallback { get; set; }


Property Value

OpcReadValueRangePropertyValueCallback

A OpcReadValueRangePropertyValueCallback used to read the value range property value as the type OpcValueRange. The value can also be a null reference (Nothing in Visual Basic).



Remarks

This callback is used in call chain with the ReadPropertyValueCallback and will be called with the outcome of that callback routine (in case there is one defined).

Value

Gets or sets the value of the property node.

C# 

public OpcValueRange Value { get; set; }


Property Value

OpcValueRange

A OpcValueRange representing the value of the property node. This can be also a null reference (Nothing in Visual Basic).

WriteValueRangePropertyValueCallback

Gets or sets a callback used to write the value range property value.

C# 

public OpcWriteValueRangePropertyValueCallback WriteValueRangePropertyValueCallback { get; set; }


Property Value

OpcWriteValueRangePropertyValueCallback

A OpcWriteValueRangePropertyValueCallback used to write the value range property value as the type OpcValueRange. The value can also be a null reference (Nothing in Visual Basic).



Remarks

This callback is used in call chain with the WritePropertyValueCallback and will be called with the outcome of that callback routine (in case there is one defined).
