LinearConversionDataType DataType definition – OPC Unified Architecture

6.6.2 LinearConversionDataType DataType definition

This structure contains a simple conversion according to the following formula. The factors (a = inititialAddend, b = multiplicand, c = divisor, d = finalAddend) are given in a Structure. X is the source value (in source unit) and f(x) the target value (in target unit). The structure is defined in Table 54.

The values of the structure can also be used for a simple inverse conversion. It can be used if a Client wants to write a value to the Server. The value y¹ is the value that the Client wants to write to the Server in the named alternative unit and x¹ is the value the Client actually has to write to the Server instead.

Table 54 – LinearConversionDataType Structure

Name	Type	Description
LinearConversionDataType	Structure	Subtype of Structure defined in OPC 10000-5
InitialAddend	Float	The initial addend of linear conversion.
Multiplicand	Float	The multiplicand of linear conversion.
Divisor	Float	The divisor of linear conversion.
FinalAddend	Float	The final addend of linear conversion.

Its representation in the AddressSpace is defined in Table 53.
