IT-OT (Information Technology–Operational Technology) convergence is the integration of enterprise IT systems (SAP, PLM, cloud platforms, analytics) with OT systems that control physical production processes (SCADA, DCS, PLC, MES, industrial sensors). Convergence matters for manufacturing because it enables real-time production data to flow from shop floor OT systems into SAP for automated production confirmation, into analytics platforms for OEE monitoring, and into AI programmes for predictive maintenance and quality intelligence — capabilities that require OT data but are impossible without IT-OT integration. The challenge is achieving this connectivity without creating cybersecurity exposure that puts OT systems — and the physical production processes they control — at risk from IT-originated cyber threats.

EMUG MERGE is the five-phase IT-OT convergence delivery methodology: Map — IT and OT landscape assessment with asset inventory and connectivity mapping; Evaluate — security gap analysis against ISA/IEC 62443 and integration requirements definition; Route — architecture design covering network segmentation, DMZ design, security controls, and integration data flows; Go-live — phased deployment and commissioning maintaining operational continuity throughout; Evolve — OT security monitoring, governance establishment, and convergence expansion. MERGE addresses the two most common IT-OT convergence failures: building integration without adequate security controls that creates OT cyber risk, and over-securing OT systems to the point where no useful data reaches IT systems.

ISA/IEC 62443 is the international industrial cybersecurity standard defining requirements for secure industrial automation and control systems (IACS). It defines a zones and conduits model: OT systems are grouped into security zones based on their criticality and security requirements, and communication between zones passes through conduits with defined security controls. EMUG MERGE applies ISA/IEC 62443 by: mapping existing OT assets to security zones, identifying unprotected zone boundaries and unsecured conduits, designing the target zone architecture with appropriate security controls at each boundary, implementing firewalls, unidirectional security gateways (data diodes), and DMZ architecture that meets the required security level for each zone, and documenting the security architecture for regulatory and cyber insurance compliance.

EMUG Tech integrates SCADA and OT data with SAP through a layered architecture: OT field data is collected by historian databases (OSIsoft PI, GE Proficy, Ignition) at the OT layer; historian data passes through a DMZ-hosted integration layer using OPC-UA, REST APIs, or MQTT protocols; SAP Manufacturing Integration and Intelligence (MII) or custom middleware receives the structured data and maps it to SAP objects (production orders in PP, maintenance notifications in PM, quality inspection lots in QM, goods movements in WM). This architecture keeps the OT historian on the OT network side of the DMZ while making the integrated data available to SAP without direct OT-to-SAP connectivity that would bypass security controls.

EMUG Tech deploys edge computing as part of IT-OT convergence where real-time local processing is required — AI quality inspection, predictive maintenance inference, local OEE calculation, and process analytics that cannot tolerate cloud round-trip latency on a production line. Edge hardware selection (NVIDIA Jetson Orin, Intel NUC, Advantech IPC) is specified in the MERGE Route phase based on compute requirements and production environment constraints. Edge devices are placed on a dedicated OT DMZ network segment with controlled connectivity to both OT sensors and IT data collection infrastructure. OTA update management ensures edge AI models can be updated without physical access to production line hardware.

IT-OT convergence is the data infrastructure prerequisite for predictive maintenance and manufacturing AI programmes. Predictive maintenance AI requires continuous vibration, temperature, and acoustic sensor data from OT equipment to reach the AI model training and inference infrastructure — impossible without a secure, reliable data pipeline from OT historians to the AI platform. Computer vision quality inspection requires camera data and production trigger signals from OT PLC systems to reach edge AI hardware — requiring OT network connectivity design. OEE analytics requires real-time production count, downtime, and quality data from SCADA and MES to reach SAP and analytics dashboards. EMUG MERGE designs the IT-OT data infrastructure that makes these AI programmes possible before EMUG PRISM or FORGE delivers the AI capability on top of it.

A focused IT-OT convergence programme for a single manufacturing site — covering landscape assessment, security architecture design, network segmentation implementation, historian-to-SAP integration, and security monitoring activation — typically takes 6 to 12 months from Map phase start to Go-live completion. A multi-site enterprise IT-OT convergence programme typically takes 18 to 30 months, phased site by site to manage operational risk and resource requirements. The MERGE Evaluate phase (8 to 12 weeks) produces a detailed architecture and business case that can be submitted for capital approval before the full convergence programme investment is committed.
