Namespace: OSIsoft.AF.Asset
Assembly: OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182

Syntax

[ObsoleteAttribute("This property uses a PI SDK COM object which may not be available on all platforms.")]
public void FromPIValue(
	Object piValue
)

<ObsoleteAttribute("This property uses a PI SDK COM object which may not be available on all platforms.")>
Public Sub FromPIValue ( 
	piValue As Object
)

Dim instance As AFValue
Dim piValue As Object

instance.FromPIValue(piValue)

public:
[ObsoleteAttribute(L"This property uses a PI SDK COM object which may not be available on all platforms.")]
void FromPIValue(
	Object^ piValue
)

[<ObsoleteAttribute("This property uses a PI SDK COM object which may not be available on all platforms.")>]
member FromPIValue : 
        piValue : Object -> unit

Parameters

piValue: Type: SystemObject
The PISDK.PIValue object to be used when setting the fields of this AFValue object.

Remarks

Sets the value of this object from a PISDK.PIValue object. This method can be used to convert a PISDK.PIValue object to an AFValue object.

Note
In the .NET 4 version of the SDK, a digital state will always be converted to an AFEnumerationValue instead of sometimes returning a digital state COM object. The AFEnumerationSet.SystemStateSet will be searched for a match. If a match is not found, a dynamic AFEnumerationValue will be returned.

Notes to Callers
This method, property, or class is not available in the .NET 8 version of the SDK.
