Industrial IoT Solutions — Your Factory, Digitised

Most factories operate with a frustrating paradox: their PLCs and SCADA systems contain rich operational data — cycle times, reject counts, energy consumption, downtime reasons — but this data is locked inside proprietary historians and control networks that operators can only access through HMI panels on the factory floor. Production managers rely on manual data collection, spreadsheets, and end-of-shift reports that arrive hours or days too late for actionable decisions. Meanwhile, competitors with real-time OEE dashboards are optimising production cycles in minutes, not shifts. Industrial IoT bridges this OT/IT gap without replacing any existing equipment. Opsio's industrial IoT solutions connect your existing PLCs and SCADA systems to cloud analytics platforms via standard industrial protocols. OPC-UA for modern controllers (Siemens S7-1500, Allen-Bradley ControlLogix, Mitsubishi MELSEC), Modbus TCP/RTU for legacy devices, and MQTT for additional sensor networks. We maintain strict ISA-95 (Purdue model) architecture principles with clear security boundaries between OT and IT networks — ensuring IIoT connectivity never compromises operational technology network integrity or production control system reliability.

The smart factory transformation delivers measurable outcomes from the first production line: real-time OEE tracking replacing manual data collection with automated availability, performance, and quality metrics updated every cycle. Per-machine energy consumption monitoring enabling ESG reporting and waste reduction. Statistical process control (SPC) with automated out-of-control alerts catching quality deviations before they produce scrap. Predictive maintenance signals from equipment sensor data preventing unplanned downtime. And MES/ERP integration providing complete production visibility from customer order to shipment.

Industrial edge gateways are the critical architectural component that makes IIoT reliable in factory environments. We deploy industrial-grade hardware from Siemens IPC, MOXA, and Advantech in DMZ network zones — handling protocol conversion between OT protocols (OPC-UA, Modbus) and IT protocols (MQTT, HTTPS), buffering data locally during network outages with guaranteed delivery when connectivity returns, and performing real-time edge analytics for latency-critical alerting that can't wait for cloud round-trips. Edge gateways ensure your IIoT system works reliably even in factories with challenging network infrastructure.

Common IIoT challenges we solve: legacy PLCs with no modern connectivity options that require Modbus RTU serial extraction, SCADA historians that can't export data in real time, OT security teams that (rightly) refuse to allow any cloud connectivity from the production network without proper segmentation, MES systems that need bi-directional data flow for production order tracking, energy monitoring that must attribute consumption to specific products for accurate costing, and quality systems that need real-time SPC data from production equipment for automated control charting. If your smart factory initiative has stalled on any of these obstacles, Opsio has the manufacturing-specific expertise to solve them.

Opsio's Industry 4.0 approach starts with a factory survey — mapping every piece of equipment, its communication protocol, existing network infrastructure, and the production data it generates. From this survey, we design a phased IIoT deployment starting with one production line as a pilot, demonstrating value with real-time OEE dashboards and energy monitoring before scaling to the full factory. This pilot-first approach lets your operations team build confidence with the technology, validates data quality and accuracy against existing manual records, and generates the ROI evidence needed to justify full-scale investment. Wondering about IIoT costs, whether your legacy equipment can be connected, or how to convince your OT security team that cloud connectivity is safe? Our factory survey answers all three questions with a concrete architecture proposal.
