XMpLant
Hexagon's P&ID Data Exchange Format
XMpLant is Hexagon's proprietary P&ID data exchange format used within the SmartPlant / HxGN SDx ecosystem. XMpLant enables structured P&ID data exchange between Hexagon SmartPlant P&ID, SmartPlant Foundation, HxGN SDx2, and third-party systems. The format predates the DEXPI standard and remains in use across operating refineries and petrochemical plants with Hexagon SmartPlant deployments.
What is XMpLant in full?
XMpLant is the Hexagon-developed P&ID data exchange format used to transfer structured P&ID data between Hexagon SmartPlant P&ID authoring tools and downstream consumers. The format encodes P&ID symbols, tags, line connections, equipment, and metadata in an XML-based schema. XMpLant predates the open DEXPI standard but remains in operational use across Hexagon SmartPlant ecosystems worldwide. Modern Hexagon HxGN SDx2 supports both XMpLant and DEXPI data exchange. See the DEXPI standard reference for the open standard alternative and the Hexagon SDx integration for Pathnovo's integration.
What context and detail applies to XMpLant?
XMpLant scope
XMpLant encodes complete P&ID structural data: symbols (ISA 5.1 instrumentation, equipment symbols, valve symbols, line symbols), tags (with ISA 5.1 letter conventions and project-specific extensions), line connectivity (process line topology), equipment metadata (datasheet references, design conditions), and project attributes. The format supports import to SmartPlant Foundation for asset information management and consumption by downstream Hexagon ecosystem tools.
XMpLant vs DEXPI
XMpLant is Hexagon-proprietary; DEXPI is an open standard developed by a consortium of process industry operators and software vendors. XMpLant remains operationally relevant for legacy SmartPlant deployments. DEXPI is the strategic path for cross-vendor P&ID data exchange. Modern Hexagon HxGN SDx2 supports both formats for cross-ecosystem flexibility.
How is XMpLant used in EPC projects?
- 01
Hexagon SmartPlant SmartPlant P&ID deployments at refineries, petrochemicals, and chemical plants export and consume XMpLant data across SmartPlant Foundation and HxGN SDx2.
- 02
Multi-vendor portfolio operators (Indian PSU refineries with mixed Hexagon SmartPlant + AVEVA Diagrams + Bentley OpenPlant deployments) use XMpLant alongside DEXPI for cross-vendor data exchange.
- 03
Brownfield digitisation projects extract structured P&ID data from legacy formats and output to XMpLant for Hexagon SmartPlant Foundation ingestion. Pathnovo's Hexagon SDx integration supports XMpLant output.
How does Pathnovo handle XMpLant?
Pathnovo's P&ID extraction product outputs structured P&ID data in multiple formats including XMpLant for Hexagon SmartPlant Foundation ingestion and DEXPI for open cross-vendor exchange. The Hexagon SDx integration documents the SmartPlant ecosystem integration pattern.
Frequently Asked Questions
What is XMpLant?
XMpLant is Hexagon's proprietary P&ID data exchange format used within the SmartPlant / HxGN SDx ecosystem. XMpLant enables structured P&ID data exchange between Hexagon SmartPlant P&ID authoring tools and downstream consumers including SmartPlant Foundation, HxGN SDx2, and third-party systems.
What is the difference between XMpLant and DEXPI?
XMpLant is Hexagon-proprietary; DEXPI is an open standard developed by a consortium of operators and software vendors. XMpLant remains operationally relevant for legacy SmartPlant deployments. DEXPI is the strategic path for cross-vendor P&ID data exchange. Modern Hexagon HxGN SDx2 supports both formats.
Does Pathnovo support XMpLant output?
Yes. Pathnovo's P&ID extraction product outputs structured P&ID data in XMpLant format for Hexagon SmartPlant Foundation ingestion alongside DEXPI for open cross-vendor exchange. The Hexagon SDx integration documents the SmartPlant ecosystem integration pattern.
When is XMpLant used?
XMpLant is used within Hexagon SmartPlant ecosystem deployments at refineries, petrochemicals, and chemical plants. The format supports data exchange between SmartPlant P&ID authoring tools, SmartPlant Foundation, and HxGN SDx2. Operators with Hexagon ecosystem commitments routinely use XMpLant.
