The Unified Namespace: Real-Time Factory Telemetry Without the Enterprise Price Tag

Legacy Modbus PLCs bridged to MQTT and Grafana delivered live OEE and downtime alerts at a fraction of SCADA licensing — fully owned infrastructure, zero subscriptions.

The Client's Problem

A local manufacturing facility was operating blind. Legacy machines on Modbus produced no real-time data — management relied on manual end-of-shift paper reports for downtime and production rates. Enterprise SCADA vendors quoted astronomical licensing fees for basic dashboards.

The OceanSoft Solution

Implemented an Industrial IoT stack on Unified Namespace (UNS) architecture: bridged legacy Modbus PLCs to a lightweight MQTT broker and surfaced real-time machine telemetry through secure, custom Grafana dashboards on infrastructure the client owns outright.

The Measurable Outcome

Delivered real-time OEE tracking and automated downtime alerts for a fraction of traditional SCADA costs. Management moved from end-of-shift paper reports to live factory visibility overnight — no vendor licensing fees and no subscription dependency.

From Paper Reports to Live Telemetry

Shop-floor PLCs spoke Modbus but had no path to operations dashboards. Supervisors filled end-of-shift forms while management discovered downtime and throughput problems hours too late. Quotes from enterprise SCADA vendors priced basic visibility out of reach.

UNS Architecture at a Glance

We adopted a Unified Namespace pattern so every machine state change publishes to a single MQTT topic hierarchy — no point-to-point integrations per machine.

  • Modbus gateway — edge device polls legacy PLCs and normalises registers to JSON payloads
  • MQTT broker (Mosquitto) — lightweight, on-prem, no per-tag licensing
  • InfluxDB — time-series store for cycle counts, fault codes, and run states
  • Grafana — custom OEE, downtime Pareto, and shift comparison dashboards

Operators see live line status; management sees cross-shift rollups without waiting for paper handoffs.

Why Not Traditional SCADA?

Per-seat licensing, historian modules, and annual maintenance contracts scaled poorly for a single-site plant that only needed OEE and downtime alerts. The self-hosted stack delivers predictable capital cost with dashboards and alert rules the client controls — no vendor roadmap dependency.

Automated Downtime Response

Threshold rules in Grafana route SMS and email when lines stop unexpectedly or cycle times drift beyond SPC limits. Maintenance gets signal while the event is still happening, not at the end of the shift.
