What we deliver
Twara Technologies engineers industrial IoT systems that bring data out of plants, workshops, utilities and process facilities and put it in front of the people who plan, maintain and improve operations. We work with the equipment you already have, respect the safety and availability demands of operational technology (OT), and build data flows that are useful to the business without exposing control systems to new risk.
Typical scope
- Survey of machines, PLCs, drives, meters, existing SCADA or historian systems and network topology.
- Selection of signals that matter: machine state, counts, alarms, energy, temperatures, pressures, vibration.
- Edge gateway design: protocol drivers, local buffering, time-stamping and pre-processing.
- Retrofit sensing where machines expose no usable data.
- Network zoning between control networks, the gateway layer and enterprise IT.
- Dashboards for overall line status, downtime reasons, energy use and maintenance indicators.
- Rules for alerts and escalation, and links to maintenance work orders.
- Integration with ERP, MES, historians or data platforms.
Technologies we work with
- Industrial protocols: OPC UA, Modbus TCP and RTU, and vendor protocols through established drivers. The OPC Foundation describes OPC UA as a platform-independent, service-oriented architecture, first released in 2008, with built-in security features such as encrypted sessions, message signing and certificate-based application authentication, plus a rich information model.
- Messaging: MQTT, an OASIS Standard, often with a structured payload convention so that devices and applications agree on topics and data types.
- Edge software: Node-RED for straightforward flows, containerised services on industrial PCs or gateways for more complex processing, and cloud providers’ edge runtimes where a cloud platform has been chosen.
- Storage and analytics: time-series databases, data lakes or warehouses, and dashboarding tools such as Grafana or custom web applications.
- Connectivity on site: wired Ethernet wherever possible; industrial Wi-Fi, private cellular or LoRaWAN for hard-to-cable areas.
How we choose: we prefer whatever the existing controllers already support well, read-only access before any write capability, and open protocols over proprietary ones when there is a genuine choice.
How we approach it
- Pick a focused problem. Unplanned downtime on one line, energy use in one building, or quality drift on one process is a better start than “connect everything”.
- Survey and inventory. Walk the site with your engineers, record signals and constraints, and agree shutdown windows for any physical work.
- Design zones and flows. Document which data moves where, through which components, and who can reach what.
- Pilot on one area. Install gateways and dashboards, validate readings against local instruments and gather feedback from operators.
- Scale site by site. Reuse templates for machine types and sites so each new rollout is faster and more consistent.
- Support and improve. Monitor gateways, maintain drivers through equipment changes and add analytics as data accumulates.
Security, privacy and quality
Industrial systems carry safety and availability risks that office IT does not. We align our designs with the ISA/IEC 62443 series, which addresses cybersecurity for industrial automation and control systems across their lifecycle and divides responsibility between asset owners, product suppliers, system integrators and service providers. In practice that means:
- Segmenting networks so that gateways and cloud connections never sit directly on control networks.
- Read-only data collection by default, with any write-back separately designed, reviewed and approved.
- Unique credentials, certificates and least-privilege accounts for every gateway and service.
- Documented change control for gateway software and configuration.
- Planning logging and incident reporting with India’s CERT-In directions, which list attacks on critical infrastructure, SCADA and operational technology systems, and attacks on IoT devices, among the incident types to be reported within 6 hours of noticing them.
Quality checks include validating collected values against local instruments, testing behaviour during network loss and gateway restarts, and signing off each machine’s data mapping with your engineers.
Engagement options
- Site assessment: a fixed-scope survey and reference architecture for one or more sites.
- Pilot deployment: connect a defined area and prove the value before wider investment.
- Multi-site rollout: templated deployment, integration and training across your estate.
- Ongoing support: monitoring, driver maintenance and new analytics as operations change.
