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
Pure-text parser for Studio 5000 L5K controller exports. Recognises
TAG/END_TAG, DATATYPE/END_DATATYPE, and PROGRAM/END_PROGRAM blocks,
strips (* ... *) comments, and tolerates multi-line entries + unknown
sections (CONFIG, MOTION_GROUP, etc.). Output records — L5kTag,
L5kDataType, L5kMember — feed L5kIngest which converts to
AbCipTagDefinition + AbCipStructureMember. Alias tags and
ExternalAccess=None tags are skipped per Kepware precedent.
AbCipDriverOptions gains an L5kImports collection
(AbCipL5kImportOptions records — file path or inline text + per-import
device + name prefix). InitializeAsync merges the imports into the
declared Tags map, with declared tags winning on Name conflicts so
operators can override import results without editing the L5K source.
Tests cover controller-scope TAG, program-scope TAG, alias-tag flag,
DATATYPE with member array dims, comment stripping, unknown-section
skipping, multi-line entries, and the full ingest path including
ExternalAccess=None / ReadOnly / UDT-typed tag fanout.
Closes#229
