WorkVisual (.wvs) & KUKA.Sim (.vcmx) Engineering Suites

Direct in-memory inspection of WorkVisual project topologies, fieldbus mappings, and 3D simulation validation.

---

Overview

Modern robotics workflows depend on engineering project files from KUKA WorkVisual (.wvs, .wvps) and KUKA.Sim / Visual Components (.vcmx, layout.rsc). Previously, inspecting hardware bus mappings or debugging 3D simulation deadlocks required launching resource-heavy CAD packages.

The WorkVisual & VCMX Suites provide zero-unpack archive parsing, bus topology cross-exporting, simulation race validation, and direct simulation-to-KRL code generation directly within VS Code.

WorkVisual (.wvs / .wvps) Topology Inspector (krl.inspectWvsTopology)

• Zero-Unpack Archive Inspection: Reads binary .wvs / .wvps project archives in-memory without disk extraction.
• XML Metadata Decoder: Decodes hex-encoded XML metadata (_x003C_, _x0022_) from Solution.MetaData.
• KOP Catalog Extraction: Extracts installed option package catalogs (KUKA.EthernetKRL, KUKA.SafeOperation, KUKA.GripperSpotTech, KUKA.Profinet), runtime KSS version, and controller serial identifiers.
• Fieldbus Bus Mapping: Parses EtherCAT couplers (EcatDiag_*.xml), Virtual I/O buses, and Profinet device slices.
• Fieldbus Tag Exporter: Automatically maps $IN and $OUT connections to Siemens TIA Portal XML/SDF, Beckhoff TwinCAT 3 GVL, and EPLAN CSV.

KUKA.Sim & Visual Components (.vcmx) Suite

1. Simulation Workcell Inspector (krl.inspectVcmxLayout)

• Two-Layer layout.rsc Parser: Reads 3D cell components directly from .vcmx archives without unpacking.
• Extracted Entities: Manipulator kinematics (rSimKinController), discrete signals (rSimBooleanSignal), conveyor transport links (ProductType), and robot process logic (ProgramData).

2. Simulation Race & Deadlock Validator (krl.validateVcmxSimulation)

Detects and safely repairs four critical simulation flaws that cause 3D workcells to freeze:

Bug Code	Classification	Root Cause & Impact
VCMX001	Edge-Triggered Deadlock	IWaitSignalStatement placed after ITransportOutStatement causing permanent cell stall after one cycle
VCMX002	Timeout Fallthrough	IWaitSignalStatement with non-zero timeout or disabled trigger violating deterministic handshakes
VCMX003	Product Leak	Missing product variable reset after TransportOut causing simulation engine flow breakdown
VCMX004	Dangling Signal	Empty or unresolved signal reference in component logic

• Safe Auto-Repair: Applies surgical patches to layout.rsc with automated .bk1, .bk2 backup preservation.

3. VCMX to KRL Post-Processor (krl.exportVcmxToKrl)

• Converts simulation process routines (LinMotion, PtpMotion, SetSignal, WaitSignal, Delay) directly into production-grade KRL .src and companion .dat modules.
