For decades the factory floor and the back office lived in separate worlds. Operational technology (OT) ran the machines: PLCs, SCADA, sensors and controllers, focused on uptime and safety. Information technology (IT) ran the business: ERP, analytics and the cloud. The two rarely spoke. OT/IT convergence is the work of connecting them so that real-time machine data and business systems finally share one language, and it has quietly become the prerequisite for everything modern manufacturers want to do, from accurate OEE to artificial intelligence.
You cannot calculate trustworthy OEE, automate maintenance or train a useful AI model if the data describing what your machines are actually doing never leaves the shop floor. Convergence is how that data gets out, in context, in real time.
When OT data meets IT systems, machine reality becomes live OEE and maintenance insight.
OT/IT convergence is the integration of operational technology systems (the equipment and control layer that runs production) with information technology systems (the software and data layer that runs the business). In practice it means machine-level data from PLCs and SCADA flows reliably and securely into systems where it can be analysed, reported and acted on, and business context flows back down to the floor.
The goal is not to merge the two teams or technologies into one, but to make them interoperate so a stoppage on a line and its cost, cause and fix can be seen as one connected story.
Real-time OEE. Availability, performance and quality can only be measured accurately when machine data is captured directly, not typed in after the shift.
Faster, smarter maintenance. Connecting equipment signals to maintenance systems means issues trigger action automatically instead of waiting to be noticed.
AI readiness. Models need a continuous, contextualised stream of operational data. Without convergence, that stream does not exist. As we explored in our piece on dark data in manufacturing, ungathered machine data is a dead end for AI.
One source of truth. Convergence is the practical answer to the data silos that keep production and business numbers from ever agreeing.
OT and IT were built for different priorities. OT prizes stability, safety and uptime, and runs equipment that may be decades old with proprietary protocols. IT moves fast and prizes connectivity and security patching. Bridging them raises real concerns: cyber-security exposure when once-isolated equipment goes online, protocol incompatibility, and the cultural gap between two teams that have rarely shared goals. These are solvable, but they explain why so many plants still leave machine data stranded.
Start with a use case, not a rip-and-replace. Pick one high-value outcome, such as real-time OEE on a critical line, and connect only what that needs.
Map your data sources. Identify which PLCs, sensors and systems hold the data, and what protocols they speak.
Use a platform that speaks both languages. Choose tooling that connects to the OT layer and to IT systems (ERP, cloud) without custom plumbing for every machine.
Secure the connection by design. Segment networks, control access and monitor traffic so connectivity does not become an attack surface.
Govern the data. Apply consistent definitions and ownership so the converged data is trustworthy, as covered in our guide to manufacturing data governance.
Fabrico is built for exactly this gap. It integrates directly with the OT layer (PLCs, SCADA) to capture real-time machine data, and connects through APIs to ERP and other IT systems for bidirectional data flow. That means machine performance, downtime, quality and maintenance are unified in one platform, with the business context attached, rather than scattered across the floor and the back office. The converged result is live OEE, automated maintenance triggers, and a clean, contextualised data foundation ready for analytics and AI.

OT (operational technology) is the hardware and software that runs physical equipment, such as PLCs, SCADA and sensors. IT (information technology) is the systems that run data and business processes, such as ERP and the cloud.
Accurate OEE depends on real-time machine data. Convergence is what gets that data off the equipment and into the systems that calculate and report it, replacing manual estimates.
It can be if done carelessly. Done properly, with network segmentation, access control and monitoring, the data benefits are achieved without exposing equipment to unnecessary risk.
