ITcAdsRawAny Interface

Interface defining ADS read/writes addressed by IndexGroup/IndexOffset or handle.

Namespace: TwinCAT.Ads
Assembly: TwinCAT.Ads.Abstractions (in TwinCAT.Ads.Abstractions.dll) Version: 7.0.0+e56d35ccc4675faac24789a4aab60071fc61d470

Syntax

C#

public interface ITcAdsRawAny

The ITcAdsRawAny type exposes the following members.

Methods

	Name	Description
	ReadAnyAsync(UInt32, Type, Int32, CancellationToken)	Reads the value of an Anytype (Primitive type) asynchronously.
	ReadAnyAsync(UInt32, UInt32, Type, Int32, CancellationToken)	Reads the value of an AnyType (Primitive type) asynchronously.
	TryReadAny(UInt32, Type, Object)	Reads a value.
	TryReadAny(UInt32, Type, Int32, Object)	Read the value of an AnyType (Primitive type)
	TryReadAny(UInt32, UInt32, Type, Object)	Reads the value as specified type.
	TryWrite(UInt32, UInt32, Object)	Writes an AnyType value (struct)
	TryWriteT(UInt32, UInt32, T)	Writes an AnyType value.
	TryWriteAny(UInt32, Object)	Writes an AnyType value.
	TryWriteAny(UInt32, Object, Int32)	Writes an AnyType value.
	TryWriteAny(UInt32, UInt32, Object)	Writes an AnyType value.
	TryWriteAny(UInt32, UInt32, Object, Int32)	Writes an AnyType value.
	WriteAnyAsync	Write the value of an Anytype (Primitive type) asynchronously.

Remarks

Because no symbolic information is available here (in opposite to IAdsSymbolicAccess), these read/write methods rely on type information that is given by the value itself or by method parameter. Therefore the marshalling of the values is limited to

Primitive types
Arrays of primitive types
Types that are specified by ADS AnyTypes.
Blittable complex .NET Types (StructLayout of .NET Types is equal the ADS Device symbol datatype.)

Type of value Parameter	Necessary Arguments (args)
string	args[0]: Number of characters in the string typed as FixedLengthZeroTerminated.
string[]	args[0]: Number of characters in each string typed as FixedLengthZeroTerminated.
Array	args: Dimensions of Array as int[]
