Industrial IoT

H2LooP.ai is building specialized Language Models (SLMs) tailored for system software engineers in high-stakes industrial automation environments. Our models are fine-tuned on real-world C/C++ codebases used in programmable logic controllers (PLCs), edge gateways, sensor networks, and SCADA systems. H2LooP enables deep code comprehension, system visualization, and auto-generation of documentation—accelerating engineering velocity while maintaining traceability and control. We help OEMs and industrial solution providers unlock insights from legacy control logic and transition confidently toward modern, interoperable platforms.

Challenges in Industrial IoT

Industrial IoT systems often rely on decades-old C/C++ code running on PLCs and edge devices, with little to no documentation. This makes maintenance, traceability, and integration with modern platforms slow and error-prone. Engineering teams spend weeks reverse-engineering legacy logic, increasing the risk of regressions and broken dependencies during platform transitions. Moreover, compliance with standards like IEC 61131, ISO/IEC 27001, and ISA/IEC 62443 requires full system visibility,something most legacy systems lack, leading to costly delays and audit risks.

Undocumented Legacy Code

Most PLCs and edge devices rely on decades-old C/C++ codebases with little to no documentation, making maintenance and traceability extremely difficult.

Slow Integration and Migration

Engineers spend weeks reverse-engineering legacy control logic, leading to slow, error-prone, and risky integration or platform migration efforts.

Broken Dependencies in Platform Transitions

Replatforming or refactoring without architectural clarity often introduces broken dependencies and architectural mismatches.

Risk of Regressions

Lack of visibility into legacy system behavior leads to unexpected regressions during modernization or system upgrades.

Costly Re-Certification Delays

Architecture gaps during platform transitions frequently result in failed compliance checks and delays in recertification cycles.

Stringent Compliance and Audit Demands

Standards like IEC 61131, ISO/IEC 27001, and ISA/IEC 62443 require full system visibility and traceability from logic to implementation—capabilities most legacy systems lack.

Why H2Loop ?

01 Legacy Code to Functional Docs

H2LooP auto-generates IEC 61131-style documentation and I/O flow diagrams directly from embedded C/C++ code, eliminating guesswork.

02 Full System Architecture Visibility

Gain deep insights into cross-layer behavior from RTOS tasks and interrupt routines to fieldbus driver interactions and protocol stacks.

03 Audit-Ready Technical Records

Support compliance workflows by generating traceable documentation directly from firmware, aligning with industrial cybersecurity and safety standards.

04 Faster Engineer Ramp-up

Equip new engineers with interactive system maps and code explanations, dramatically reducing onboarding time and dependency on tribal knowledge.

SLMs Purpose-Built for Industrial IoT System Software

H2LooP is purpose-built to support engineering teams developing reliable, real-time, and secure software for Industrial IoT environments. Our domain-specific specialized Language Models (SLMs) are trained on production-grade C/C++ code powering PLCs, edge controllers, SCADA systems, and sensor networks. H2LooP deeply understands legacy firmware, RTOS tasking, fieldbus protocols (e.g., Modbus, CANopen, PROFIBUS), and time-sensitive networking stacks. It equips R&D, maintenance, and compliance teams with an AI-native view of control systems—accelerating fault diagnostics, easing platform integration, and auto-generating documentation aligned with IEC 61131, ISO 21434, and ISA/IEC 62443 cybersecurity standards.
