Architecture
Connectivity across every layer of your operation.
SPA™ is not a point-to-point integration tool. It is a symmetrical operational data fabric designed to solve aggregation across the full technology stack — from field instrumentation at Level 0 through enterprise and cloud systems at Level 5. Unlike conventional architectures that move data upward through rigid, sequential pipelines, SPA™ enables information to flow symmetrically across layers, systems, and domains. Each data element is precisely timestamped, validated, contextualized, and recorded with a persistent chain of integrity.
The result is temporal coherence across the operation: field conditions become immediately meaningful at the machine, process, enterprise, and cloud layers while preserving fidelity, provenance, and operational context.
L5 — Enterprise
ERP, Business Intelligence, Executive Dashboards
The enterprise tier connects operational data directly into ERP systems, BI platforms, and executive dashboards — giving leadership real-time visibility into OEE, quality, and throughput without manual reporting.
L4 — Site Operations
MES, Historian, Site-wide Analytics, Scheduling
Site Operations aggregates plant-wide data for production scheduling, MES integration, and Historian archival. SPA™ ensures every event is timestamped and immutably logged as it passes through this layer.
L3 — Operations Management
MIP, Dashboards, OperationalIQ™, ReflexIQ™
The SPA™ Hub lives at L3 — the intelligence nerve center that routes, validates, and orchestrates data bidirectionally between edge devices and enterprise systems. MIP dashboards and AI Copilots operate here.
L2 — Supervisory Control
SCADA, HMI, Alarm Management, Batch Control
SCADA and HMI systems at L2 translate raw control signals into operator interfaces. SPA™ validates every alarm and batch event in real time, feeding contextual data upward while distributing setpoints downward.
L1 — Basic Control
PLCs, PACs, DCS, Motion Control, Safety Systems
PLCs, PACs, and DCS systems execute the physical control logic. SPA™ captures every state change at millisecond resolution with zero-trust validation — ensuring safety system events are permanently auditable.
L0 — Field Devices
Sensors, Actuators, Analyzers, Drives, Instruments
At the edge, sensors, actuators, drives, and instruments generate the raw process signal stream. SPA™ ingests this data with semantic structuring, creating a causally-correct lineage from physical reality to enterprise insight.
Security Posture
SPA™ implements zero-trust principles at every layer boundary. No component is trusted implicitly — every connection is authenticated, every message validated by ReflexIQ™.
