3.1.4 DevelopmentPlatform

DevelopmentPlatform suite of tools and/or programming languages used to create software
OPC-10000-6 – OPC Unified Architecture - Part 6: Mappings

4 Overview

which hides the details of the Stack implementation. An API depends on a specific DevelopmentPlatform . Note that the datatypes exposed in the API for a DevelopmentPlatform do not always match ... datatypes defined by the specification because of limitations of the DevelopmentPlatform. For example, Java Programming Language does not support an unsigned integer which means that any API will map unsigned

5.1.4 DateTime

range supported by the DataEncoding is outside of the range supported by a DevelopmentPlatform then decoders shall replace any below range values with DateTime.MinValue and any above range values with ... DateTime.MaxValue for the DevelopmentPlatform . If the range supported by a DevelopmentPlatform is outside of the range supported by a DataEncoding then encoders shall replace any below range values with DateTime.MinValue

5.1.5 ByteString

between a ByteString and a one-dimensional array of Byte . If a decoder for DevelopmentPlatform cannot preserve the distinction it shall convert all one-dimensional arrays of Byte to ByteStrings ... dimension arrays of Byte and one or more-dimension arrays of ByteString . If a DevelopmentPlatform does not support unsigned integers, then it will have to represent ByteStrings as arrays

5.1.9 Variant

null value for data types that support nulls such as Strings . Some DevelopmentPlatform s may not be able to preserve the distinction between a null for a DataType

5.1.10 Decimal

Decimal can parse the value and use any construct that is suitable for the DevelopmentPlatform . Note that a Decimal is like a built-in type and a DevelopmentPlatform

5.1.11 Null, Empty and Zero-Length Arrays

testing for equality, applications shall treat null and empty arrays as equal. When a DevelopmentPlatform supports the distinction, writing and reading back an array value can result in null array

5.2.2.5 DateTime

applied when dealing with date/time values that exceed the dynamic range of a DevelopmentPlatform . These rules are: A date/time value is encoded as 0 if either: The value is equal ... 00AM UTC. The value is the earliest date that can be represented with the DevelopmentPlatform 's encoding. A date/time is encoded as the maximum value for an Int64 if either

format. The earliest and latest date/time values that can be represented on a DevelopmentPlatform have special meaning and shall not be literally encoded in XML. The earliest date/time value ... DevelopmentPlatform shall be encoded in XML as '0001-01-01T00:00:00Z'. The latest date/time value on a DevelopmentPlatform shall be encoded

5.4.2.6 DateTime

decimal places required to represent the full range of the DateTime type on their DevelopmentPlatform . Decoders may truncate decimal places that exceed the range supported by the DateTime type ... their DevelopmentPlatform. DateTime values equal to "0001-01-01T00:00:00Z" are considered to be NULL values
