China Releases AI Terminal Standard for SCADA/Digital Twin Systems

On May 15, 2026, China’s Ministry of Industry and Information Technology (MIIT), State Administration for Market Regulation (SAMR), and National Data Administration jointly issued GB/T 45287-2026 Technical Requirements for Interoperability of AI Terminals in Smart Water Services. The standard mandates DLMS/COSEM protocol conformance certification and IEC 62443-3-3 Security Level 3 (SL3) compliance for SCADA systems and Digital Twin platforms intended for export — making it highly relevant for smart water infrastructure vendors, industrial automation integrators, and cybersecurity solution providers serving Southeast Asian markets.

Event Overview

On May 15, 2026, MIIT, SAMR, and the National Data Administration published GB/T 45287-2026 Technical Requirements for Interoperability of AI Terminals in Smart Water Services. The standard stipulates that SCADA systems and Digital Twin platforms designed for export must pass DLMS/COSEM protocol conformance certification and support IEC 62443-3-3 Security Level 3 (SL3). It has been referenced as an implicit requirement in tender specifications by Singapore’s Public Utilities Board (PUB) and Vietnam’s Electricity of Vietnam (EVN) for smart water plant projects.

Industries Affected

Export-Oriented Industrial Automation Vendors

These vendors supply SCADA systems to overseas water utilities. The standard directly affects product certification pathways: DLMS/COSEM conformance is now a prerequisite for market access in jurisdictions adopting the standard as a de facto requirement. Non-compliant systems may be excluded from bidding processes even if technically functional.

Digital Twin Platform Developers

Developers offering simulation or operational twin solutions for water infrastructure must ensure their platforms integrate with DLMS/COSEM-based metering and control data sources — not only for protocol-level interoperability but also for end-to-end security alignment with SL3. This affects architecture design, third-party interface validation, and documentation requirements.

Cybersecurity Service Providers Supporting OT Environments

Providers delivering assessment, certification, or hardening services for operational technology (OT) systems must now align offerings with IEC 62443-3-3 SL3 implementation guidance specific to AI-enhanced terminal environments. SL3 compliance involves rigorous threat modeling, secure development lifecycle integration, and audit-ready evidence generation — beyond baseline OT security practices.

Systems Integrators for Smart Water Projects

Integrators bundling hardware, software, and networking components face increased due diligence obligations. They must verify DLMS/COSEM conformance certificates from upstream suppliers and validate SL3-aligned configurations across the full stack — including edge AI terminals, communication gateways, and cloud analytics layers.

Key Focus Areas and Recommended Actions

Monitor official interpretation documents and certification body announcements

The standard specifies requirements but does not yet define accredited testing laboratories or certification timelines. Exporters should track updates from China Certification & Inspection Group (CCIC), China Electric Power Research Institute (CEPRI), and international DLMS User Association-accredited labs for formal test procedures and SL3 assessment frameworks.

Identify and prioritize high-impact export markets and product lines

Singapore PUB and Vietnam EVN have already embedded the standard’s requirements into procurement criteria. Vendors should review active and upcoming tenders in these markets — especially for AI-powered leak detection, pump optimization, and real-time hydraulic modeling modules — and assess which SKUs require immediate protocol and security revalidation.

Distinguish between policy signal and contractual obligation

While GB/T 45287-2026 is a national recommended standard (not mandatory by law), its adoption by foreign utilities as a tender condition transforms it into a de facto commercial requirement. Companies should treat it as binding for targeted bids, rather than waiting for domestic enforcement mechanisms to emerge.

Initiate internal gap assessments and supplier engagement

Conduct protocol stack audits against DLMS/COSEM Edition 12 (IEC 62056-21/62056-62) and map existing security controls to IEC 62443-3-3 SL3 clauses. Engage component suppliers early to obtain updated conformance reports and SL3-aligned firmware roadmaps — particularly for embedded AI inference units and secure boot modules.

Editorial Perspective / Industry Observation

Observably, this standard functions less as a standalone technical rule and more as a synchronization mechanism — aligning China’s AI terminal development roadmap with internationally recognized utility communication and security frameworks. Analysis shows it reflects growing convergence between smart infrastructure procurement policies in Asia-Pacific, where interoperability and cyber-resilience are increasingly treated as inseparable attributes. From an industry perspective, the inclusion of DLMS/COSEM — a mature, field-proven utility protocol — signals a preference for standards-based integration over proprietary AI middleware. Current adoption by PUB and EVN suggests the standard is already operating as a market gatekeeper, not merely a future-readiness indicator. Continuous monitoring is warranted as other ASEAN utilities may follow suit in upcoming procurement cycles.

This standard marks a formal step toward embedding AI capabilities within interoperable, auditable, and security-assured operational frameworks for critical water infrastructure. It does not introduce entirely new technologies, but consolidates expectations around proven protocols and rigorously defined security levels. For stakeholders, it is best understood not as a one-time compliance milestone, but as an early marker of evolving regional procurement norms — where AI functionality is no longer evaluated in isolation, but only in conjunction with verifiable interoperability and resilience credentials.
