neoLog: industrial data logger

Every device. Every protocol. One platform.

neoLog is NeoTAQ's universal data logger — solar, telecom and industrial data logging on one edge device. Every protocol, every brand, across Asia, GCC and Africa.

Point it at your inverters, meters, gensets, batteries and sensors; neoLog discovers them, reads them, logs them, and streams them to the neoSphere cloud. Offline-first. Always on.

Data export and visualisation

  • Locally over USB
  • Locally via Modbus Gateway: connects to third party EMS and SCADA
  • Locally via FTP Push
  • Remotely via API integration

Core capabilities

Broad multi-protocol connectivity

  • Connects over Modbus RTU (RS-485 serial) and Modbus TCP (Ethernet) on the same gateway, simultaneously.
  • OPC UA compatibility extends neoLog into the SCADA and historian world through one secure endpoint.
  • Reads the full range of industrial data types and value formats, with per-device handling so different makes coexist cleanly on one bus.

Automatic device discovery

  • A discovery engine sweeps your network, identifies what's connected, and matches each device to its profile.
  • Discovered devices register live. Logging begins within seconds, with no service restart.
  • Manufacturer-aware discovery narrows the search and speeds up commissioning.

Profile-driven, zero-code onboarding

  • Add a new device model from the device library. No software change, no redeployment.
  • Each profile defines what to read, how to interpret it, which standard measurement each value maps to, and which conditions are alarms.
  • Site-level overrides tailor any installation without touching your master library.
  • Profiles are validated before they go live, so a bad configuration can't disrupt a running site.

High-integrity data acquisition

  • Each device is read on its own schedule, with bus access managed so there's no contention or corrupted readings.
  • Efficient batch reads group data into optimised requests, cutting traffic and improving responsiveness.
  • Error recovery isolates faulty points so one bad reading never stalls a device; per-device health is tracked continuously.
  • Hardware watchdog protection keeps the platform running unattended for years.

Smart aggregation

  • Raw readings consolidate into clean periodic records (averages for analog values, bounds for ranges, last-value for status), each tagged with how many readings backed it.
  • Aggregation behaviour is set per measurement, so power values average while fault codes capture correctly.

Built-in alarm engine

  • Any measurement can be an alarm with a severity level.
  • Alarms are captured with full trigger and clear history, de-duplication and fast retrieval.
  • Change-based reporting means the cloud only sees an alarm when something actually changes. No flooding.

Offline-first cloud sync to neoSphere

  • Every record is stored locally first and held until neoSphere confirms it.
  • If connectivity drops, data keeps accumulating on the edge and back-fills automatically when the link returns. Zero data loss.
  • Sync runs continuously with automatic retry and confirmation.

Monitoring and visualization

  • Real-time values, device status and alarm history stream to a built-in on-site dashboard for live local visibility.
  • In the cloud, neoSphere delivers multi-site monitoring, performance analytics, alarm management and executive overviews. Your whole fleet in one place.

Protocol compatibility

neoLog is protocol-agnostic by design. Beyond native Modbus RTU and TCP, OPC UA compatibility lets it bridge the field-device world and the enterprise world. No second system, no duplicated data.

Capability What it does
Expose over OPC UA Every connected device is available to your SCADA, historian or DCS through one standards-compliant, secure endpoint.
Ingest from OPC UA Bring data from existing OPC UA systems into the same logging, alarming and cloud-sync pipeline as everything else.
Secure access Authenticated, credentialed connections with configurable access control.

How it works

  1. Connect

    Point neoLog at the inverters, meters, gensets and batteries on your site.

  2. Log

    It reads, scales, aggregates and alarms every device, reliably, even when the internet is down.

  3. See

    Records sync to neoSphere automatically, so your whole fleet shows up in one place.

neoLog captures the data on the edge and keeps the neoSphere cloud in sync automatically: connect any device, log it reliably, see it everywhere.

Who it's for

  • Solar and hybrid plant operators who need one logger for every brand on site.
  • EPCs and system integrators commissioning mixed-vendor fleets fast.
  • Asset managers who need auditable, gap-free historical data and alarm trails.
  • OEMs wanting a white-labelable logging layer instead of building one.

The neoLog advantage

  • One gateway, every vendor. No per-brand integration projects.
  • Commission in minutes: discover, match, log. No restarts.
  • Never lose a data point. Offline-first by design.
  • Extend by configuration, not code: new devices from the device library.
  • Fits any estate: Modbus and OPC UA, field to enterprise.
  • Built for the field: watchdog-protected, self-healing, runs for years on low-power edge hardware.

What is a universal data logger?

A universal data logger records data from every asset on a site — solar inverters, telecom rectifiers, industrial meters and gensets — over open protocols. neoLog handles Modbus, OPC-UA and more on one edge device across Asia, GCC and Africa.

Does neoLog work for solar, telecom and industrial sites?

Yes. neoLog is protocol-agnostic and profile-driven — one edge unit logs solar, telecom and industrial data and syncs to neoSphere without rip-and-replace.

Part of the NeoTAQ platform

One edge hardware, one platform. What you log you can control; what you control you can store, all feeding the neoSphere cloud.
