AOI-aware browse paths: AOI instances now fan out under directional
sub-folders (Inputs/, Outputs/, InOut/) instead of a flat layout. The
sub-folders only appear when at least one member carries a non-Local
AoiQualifier, so plain UDT tags keep the pre-2.6 flat structure.
- Add AoiQualifier enum (Local / Input / Output / InOut) + new property
on AbCipStructureMember (defaults to Local).
- L5K parser learns ADD_ON_INSTRUCTION_DEFINITION blocks; PARAMETER
entries' Usage attribute flows through L5kMember.Usage.
- L5X parser captures the Usage attribute on <Parameter> elements.
- L5kIngest maps Usage strings (Input/Output/InOut) to AoiQualifier;
null + unknown values map to Local.
- AbCipDriver.DiscoverAsync groups directional members under
Inputs / Outputs / InOut sub-folders when any member is non-Local.
- Tests for L5K AOI block parsing, L5X Usage capture, ingest mapping
(both formats), and AOI-vs-plain UDT discovery fan-out.
Closes#234
Threads tag/UDT-member descriptions captured by the L5K (#346) and L5X
(#347) parsers through AbCipTagDefinition + AbCipStructureMember into
DriverAttributeInfo, so the address-space builder sets the OPC UA
Description attribute on each Variable node. L5kMember and L5xParser
also now capture per-member descriptions (via the (Description := "...")
attribute block on L5K and the <Description> child on L5X), and
L5kIngest forwards them. DriverNodeManager surfaces
DriverAttributeInfo.Description as the Variable's Description property.
Description is added as a trailing optional parameter on
DriverAttributeInfo (default null) so every other driver continues
to construct the record unchanged.
Closes#231
Adds Import/L5xParser.cs that consumes Studio 5000 L5X (XML) controller
exports via System.Xml.XPath and produces the same L5kDocument bundle as
L5kParser, so L5kIngest handles both formats interchangeably.
- Controller-scope and program-scope <Tag> elements with Name, DataType,
TagType, ExternalAccess, AliasFor, and <Description> child.
- <DataType>/<Members>/<Member> with Hidden BOOL-host (ZZZZZZZZZZ*) skip.
- AddOnInstructionDefinitions surfaced as L5kDataType entries so AOI-typed
tags pick up a member layout the same way UDT-typed tags do; hidden
EnableIn/EnableOut parameters skipped. Full directional Input/Output/InOut
modelling stays deferred to PR 2.6.
AbCipDriverOptions gains parallel L5xImports collection (mirrors
L5kImports field-for-field). InitializeAsync funnels both through one
shared MergeImport helper that differs only in the parser delegate.
Tests: 8 L5X fixtures cover controller- and program-scope tags, alias skip,
UDT layout fan-out, AOI-typed tag, ZZZZZZZZZZ host skip, hidden AOI param
skip, missing-ExternalAccess default, and an empty-controller no-throw.
Closes#230
