Industrial automation is moving fast, and data is the new currency.
Sundar Techno Solutions (STS) proudly introduces the ultimate breakthrough in edge computing and Unified Namespace (UNS) bridging: The STS Nexus Industrial IIoT Edge Gateway Appliance. 

Say goodbye to expensive middleware applications, recurring annual software subscription renewals, and restricted vendor platforms. We have engineered a plug-and-play, hardware-embedded appliance that seamlessly bridges your physical factory floor directly to corporate cloud environments.
In standard manufacturing setups, shop-floor machines speak local operational protocols, while cloud platforms speak web-based protocols. Converting OPC-UA to MQTT solves the ultimate industrial data challenge:
• Protocol Bridging: It takes heavy, stateful, and complex industrial machine data (OPC-UA) and instantly converts it into lightweight, payload-agnostic, publish-subscribe data packets (MQTT).
• Bandwidth Reduction: Instead of constantly polling machines for data, MQTT uses a report-by-exception framework. Data is only transmitted when a value actually changes, reducing network congestion.
• Cloud Readiness: It makes legacy factory floors instantly compatible with modern IT architectures, industrial historians, and enterprise analytics platforms.
To build a modern digital pipeline, you need to connect two distinct worlds:
• OPC-UA Devices (The Shop Floor): These are operational technology (OT) assets inside the factory. They include Programmable Logic Controllers (PLCs), SCADA systems, CNC machines, and heavy field controllers (e.g., Siemens S7, Rockwell ControlLogix, Omron, Schneider) that host data points locally.
• MQTT Devices / Clients (The Cloud & Enterprise Network): These are information technology (IT) components. They include cloud platforms (AWS IoT Core, Azure IoT Hub), local or enterprise MQTT brokers (like Mosquitto or EMQX), MES/ERP applications, and data analytics dashboards that consume the streamlined data.
This conversion is the baseline engine of Industry 4.0, Smart Manufacturing, and the Unified Namespace (UNS). Industry 4.0 requires breaking down traditional data silos. By embedding this protocol conversion directly into a secure edge appliance, factories can successfully achieve:
1. Vertical Integration: Allowing a sensor on a physical conveyor belt to talk directly to an enterprise planning system.
2. Predictive Maintenance: Moving real-time high-capacity data (up to 15,000 points) to cloud-based AI modules to predict machine breakdowns before they happen.
3. Mass Scalability: Laying the structural foundation for an agile, data-driven smart factory.
Built inside a rugged, heavy-duty fanless aluminum chassis, this server-grade appliance is explicitly built to handle massive enterprise data pipelines.
• Massive 15,000 Tag Data Capacity: Purpose-built to ingest, process, and map up to 15,000 real-time active data tags simultaneously without latency or data drops.
• Server-Grade Architecture: Packed with a high-performance 12th Generation Intel® Core™ i5 Processor and a massive 32 GB RAM buffer to ensure bulletproof data caching during temporary cloud disconnections.
• Physical Network Isolation (Dual LAN): Dual dedicated Gigabit Ethernet ports guarantee maximum security. LAN 1 isolates your internal OT factory network, while LAN 2 securely routes encrypted streams to your IT corporate firewall or cellular routers.
• Zero Software Licensing Overhead: A single, one-time investment for a complete physical conversion powerhouse. No per-tag hidden fees, no annual software subscription renewals—ever.
• Hardware Excellence: As a premier manufacturer of high-end, fanless industrial box PCs, we don’t just sell software configurations; we own and build the robust physical hardware platform.
• Turnkey Engineering: We deliver a single, locked-down, plug-and-play appliance. You do not need to piece together separate hardware and software modules—it arrives 100% ready to run out of the box.
• Disruptive Total Cost of Ownership: We eliminate the thousands of dollars in annual recurring license bills that international software giants charge, passing the direct savings to you.
