Industrial Automation in Vijayawada — Intelligent Control for Every Line
Transform complex industrial processes into efficient, connected workflows. NarneTech engineers wired PLC / HMI / SCADA systems and custom LoRa wireless modules that bring machinery, sensors, monitoring and analytics onto one robust platform — with live dashboards your team can read from any device. Scale from a single line to a full facility, backed by dedicated support across India.
Deterministic, Real-Time Control for Industrial Processes
Robust wired architectures using PLCs, HMIs and SCADA for high availability, safety and predictable performance across your plant. We standardise on proven vendors and open protocols to keep your lines running and your data flowing.
The right controller for every I/O mix
Series we commonly deploy include Mitsubishi iQ-R/Q, Siemens S7-1200/1500, Delta DVP/AS and Schneider Modicon (M340/M580) — selected per I/O mix, cycle time and budget.
- HMI options. Panel HMIs sized per station for operator ergonomics and environment, with alarm banners, recipes, user roles, audit trails, multi-language screens and standardised navigation.
- SCADA platforms. ICONICS, Siemens WinCC and vendor-native suites for enterprise visualisation, alarm management and reporting — plus historian setup for trends, quality and traceability.
- Deterministic scan times and low latency for critical loops.
- High availability with redundancy options.
- EMI-resilient cabling and panelised control.
- Higher upfront cost for cabling and panels; less flexible for rapidly changing layouts.
PLC Panel
Controller + I/O, 24VDC PSU & MCBs, and industrial network switches — cleanly built and fully labelled.
Motor Control
Soft starters and VFDs, overloads & contactors, plus interlocks and safety relays engineered to your process.
Field Junctions
Numbered terminals, shielded I/O marshalling, glands and ferruling — built for fast fault-finding.
- Deliverables: GA drawings • panel schematics • cable schedule • I/O list • FAT/SAT • manuals.
Custom LoRa Modules for End-to-End Connectivity
We design and build custom LoRa edge devices and gateways that connect sensors, meters and actuators across large sites — long-range, low-power telemetry and control where wiring is impractical.
Sensor to SCADA, without the trenching
- Multi-I/O end devices (AI, DI, DO) and RS-485-to-LoRa nodes.
- LoRa gateways/bridges to PLC/SCADA via OPC UA, Modbus and MQTT.
- Over-the-air configuration, diagnostics and firmware updates.
Where it fits
- Spread-out plants, utilities, yards and tank farms.
- Condition monitoring, energy & water metering, environmental telemetry.
- Temporary setups and remote assets.
Strengths & trade-offs
- Long range, low power, fast deployment without trenching — scales from a few to hundreds of nodes.
- Throughput is lower than Ethernet networks, and link quality depends on site RF conditions and antenna placement — we survey first.
Typical LoRa Architecture
Field nodes report to a LoRa gateway, the gateway feeds PLC/SCADA via Modbus/MQTT, and an optional cloud relay powers remote dashboards.
Device Capabilities
Battery or 24V DC power options, ingress-protected enclosures, and built-in signal strength & health telemetry.
Commissioning Toolkit
Site survey and link-budget guidance, QR provisioning for nodes, plus firmware and configuration backups.
From Plant Floor to Dashboards — Secure Data Pipelines
Our edge gateways normalise PLC and LoRa data and publish via MQTT/OPC UA — powering role-based dashboards and alerts for maintenance, quality and energy teams without touching your control networks.
Edge Gateways
Protocol conversion (OPC UA, Modbus, MQTT), store & forward with local buffering, and on-prem historians and reports.
Dashboards & Alerts
OEE, downtime and energy views on any screen, with email/SMS/ChatOps notifications and role-based access control.
OT Security
Network segmentation (LAN/VLAN), least-privilege user roles, and audit logs with full change tracking.
Where We Fit — Across Processes and Utilities
Proven deployments across manufacturing, utilities, food processing and infrastructure.
Manufacturing
Assembly & material handling, machine interlocks and safety systems.
Water & Utilities
Pumps, VFDs and reservoirs with pressure and flow monitoring.
Food & Beverage
Batching & CIP skids, cold rooms and conveyor automation.
Infra & Buildings
DG/UPS integration, HVAC control and energy dashboards.
Wired vs. Wireless — Quick Guidance
Match the technology to the job: control on copper, telemetry over the air.
| Wired (PLC/HMI/SCADA) | Wireless (LoRa) | |
|---|---|---|
| Best for | Real-time control, interlocks, critical loops | Telemetry over long distances, retrofits |
| Latency | Very low, deterministic | Low–moderate (not for high-speed control) |
| Scalability | Panel & network capacity driven | Node-based; add devices as needed |
| Notes | Higher upfront cabling costs | Plan RF survey & antenna placement |
