ISA Publishes New SCADA Systems Standard

Key Takeaways

• ANSI/ISA‑112 Part 1 offers vendor‑neutral SCADA lifecycle framework
• Applies to water, oil, power, transport, and defense sectors
• Guides design, operation, maintenance, expansion, and audit processes
• Supports security and connectivity upgrades for legacy systems
• Committee plans additional parts on review processes and architectures

Summary

The International Society of Automation (ISA) has released ANSI/ISA-112.00.01-2025, SCADA systems—Part 1, a vendor‑neutral, technology‑independent framework that defines the SCADA lifecycle, diagrams, and terminology. The standard targets utilities, system integrators, and operators across water, oil & gas, power, transportation, and other critical infrastructure sectors. It provides a functional architecture model and standardized workflows for designing, building, operating, maintaining, expanding, and auditing SCADA environments. ISA’s development committee, now over 350 experts, will extend the series with additional parts covering lifecycle review and architecture guidance.

Pulse Analysis

The release of ISA‑112 Part 1 arrives at a pivotal moment for supervisory control and data acquisition (SCADA) technology. As industrial operations become increasingly digitized, the lack of a common language and lifecycle methodology has hampered cross‑industry collaboration and slowed adoption of advanced security measures. By codifying diagrams, terminology, and a functional architecture model, the new ANSI‑approved standard gives engineers a reference point that transcends vendor lock‑in and regional regulatory quirks, fostering a more interoperable ecosystem.

For operators in water treatment, oil and gas pipelines, electric transmission, and transportation networks, the standard offers a clear roadmap to modernize aging assets. Its standardized workflows streamline the transition from legacy hardware to cloud‑enabled, cybersecurity‑hardened platforms, cutting engineering effort and reducing downtime. Moreover, the emphasis on end‑user standards and audit processes equips utilities with measurable compliance checkpoints, which can translate into lower insurance premiums and stronger stakeholder confidence.

Looking ahead, ISA’s commitment to expand the series with parts focused on lifecycle review and architecture signals a long‑term strategy to keep SCADA practices aligned with emerging technologies such as edge computing and AI‑driven analytics. The global volunteer committee—now over 350 experts—ensures the standard reflects diverse operational realities, increasing its appeal worldwide. Upcoming webinars and training sessions will help organizations translate the guidance into actionable projects, accelerating industry‑wide adoption and setting a new benchmark for resilient, future‑proof SCADA deployments.
