Who we build industrial IoT systems for

Plant managers and operations directors (200–2,000 employees)

You’re moving from a single IIoT pilot to plant-wide rollout, and the ROI has to land in under 18 months. You need a partner who speaks OT — OPC-UA, Modbus TCP, PROFINET — and who can connect aging machines without disrupting production. We instrument brownfield equipment, push the data to your historian or cloud, and build the dashboards your maintenance and quality teams actually use.

OEMs and industrial equipment manufacturers

You build machines and want to ship them connected — remote monitoring, usage-based service contracts, over-the-air firmware. We design the embedded electronics and gateway firmware, the secure cloud channel, and the fleet-management layer so your equipment becomes a recurring-revenue platform, not just a one-time sale.

System integrators and Industry 4.0 teams

You’re delivering a digital-transformation program and need an engineering partner to own a specific layer: an OPC-UA / MQTT edge gateway, an IEC 62443-aware network segmentation, or a custom predictive-maintenance model. We slot into your project and deliver an auditable, documented module.

Standards and frameworks we work to

Transparency note: Amotus does not hold a corporate IEC 62443 or ISO/IEC 27001 certificate. We engineer to the requirements of these standards and integrate into your organization’s OT-security and quality programs. Our deliverables (network segmentation plans, threat models, SBOMs, test records) are structured to be reviewed by your internal auditors, your OT-security team, and your insurers.

Our services for industrial & manufacturing

Industrial IoT edge gateways

Edge hardware and firmware that bridge legacy PLCs and sensors to the cloud: OPC-UA / Modbus / PROFINET on the field side, MQTT Sparkplug B or OPC-UA pub/sub northbound, local buffering for unreliable links, store-and-forward.

Deliverables: gateway hardware design or BOM, firmware source, protocol mapping document, edge-to-cloud architecture, commissioning guide.

Predictive & condition-based maintenance

Vibration, current-signature, temperature, and acoustic sensing on rotating and process equipment, with edge or cloud analytics that flag anomalies before failure. We start from your failure modes (FMEA), not from a generic model.

Deliverables: sensor selection & placement plan, data pipeline, baseline anomaly model, alerting integration, retraining playbook.

OT cybersecurity (IEC 62443-aware)

Network segmentation (zones & conduits), secure boot and signed firmware on edge devices, encrypted transport (TLS / OPC-UA security policies), Software Bill of Materials, and a defensible patch strategy for equipment that can’t be rebooted at will.

Deliverables: zone/conduit diagram, threat model, SBOM (SPDX or CycloneDX), hardening checklist, patch-management plan.

SCADA / MES / historian integration

We connect new IoT data to the systems you already run — Ignition, Wonderware/AVEVA, Kepware, OSIsoft PI, or a custom historian — using ISA-95 modelling so the data is contextualized, not just timestamped points.

Deliverables: ISA-95 data model, tag mapping, integration adapters, contextualized historian schema.

Brownfield retrofit & machine connectivity

Adding sensing and connectivity to equipment that was never designed for it — non-invasive current clamps, retrofit I/O, protocol converters — so you get data without re-certifying the machine or voiding warranties.

Deliverables: retrofit assessment, non-invasive instrumentation plan, converter selection, safety review.

Industrial connected-product firmware (for OEMs)

Embedded firmware for machines you sell: remote diagnostics, usage metering, secure OTA updates, and a fleet portal. Built for the long service life and harsh environments of industrial hardware.

Deliverables: firmware source with traceability, secure OTA mechanism, fleet/back-end architecture, long-term maintenance plan.

Our industrial methodology — pilot to plant-wide scale

1. Use-case & ROI framing — pick the failure mode or loss (downtime, scrap, energy) with the clearest payback, define the baseline KPI
2. Connectivity & security assessment — inventory protocols, map the OT network, identify IEC 62443 zones & conduits
3. Instrumented pilot — one line or asset class, real data, measurable target — typically 8–14 weeks
4. Validation against the baseline — does the pilot move the KPI? Decide go / no-go on facts, not vendor promises
5. Industrialization — hardening, security review, integration with SCADA/MES, repeatable deployment kit
6. Scale & operate — plant-wide rollout, monitoring, model retraining, support plan

The number-one reason IIoT pilots never scale is that they were never tied to a baseline KPI. We design step 1 so that step 4 is an objective decision.

Project example — connected industrial monitoring product

Project: turning a piece of field equipment into a remotely monitored, cloud-connected product with secure firmware updates and a fleet dashboard — the kind of hardware-to-cloud build behind Amotus’s own connected-product work (e.g. the Tero remote control & monitoring product).

What we engineered:

• Ruggedized edge electronics with industrial-temperature components and long-term availability
• Gateway firmware bridging field protocols (Modbus / OPC-UA) to MQTT
• Secure, signed OTA update mechanism with rollback
• Cloud back-end with fleet management, alerting, and historian-friendly export

Tech stack: STM32 / NXP i.MX · FreeRTOS & Embedded Linux · OPC-UA · MQTT Sparkplug B · Fundamentum IoT platform · TLS 1.3

Most of our industrial clients operate under confidentiality agreements, so project details on this site are kept at the technical level. We can discuss relevant, reference-checkable experience under NDA during a qualification call.

Frequently asked questions — industrial IoT

How do you handle data security?

Security is a first-class design requirement, not an afterthought. We work to SOC 2 Type II–audited practices (Groupe Vectanor), with zero-trust architecture, mTLS between devices and cloud, encryption in transit and at rest, and data residency in the region you require on our multi-region Fundamentum platform (Canada, US, Europe, and more). Your data stays yours, with clear ownership and open export.

OPC-UA or MQTT — which should I use?

They solve different problems and are often used together. OPC-UA is a rich, secure, vendor-neutral industrial standard with built-in information modelling — ideal at the machine and SCADA level. MQTT (especially with the Sparkplug B specification) is a lightweight publish/subscribe transport that scales well to the cloud over unreliable networks. A common pattern is OPC-UA at the field/control level and MQTT Sparkplug B northbound to the cloud. We pick based on your network, your existing systems, and your latency needs.

How much does a predictive-maintenance project cost?

A focused pilot on one asset class (say 10–50 similar machines) typically represents 400 to 900 engineer-hours, roughly CAD $60,000 to $150,000, including instrumentation, data pipeline, and a first anomaly model. Plant-wide industrialization is scoped separately once the pilot proves the KPI. These are industry-typical ranges; your actual quote depends on machine count, sensing complexity, and integration scope.

Can you connect old machines that have no network interface?

Yes — that’s the majority of real industrial work. We use non-invasive sensing (current clamps, external vibration/temperature sensors), retrofit I/O modules, and protocol converters to instrument equipment without modifying the machine itself, which avoids re-certification and warranty issues. The data then flows through an edge gateway to your historian or cloud.

How do you keep the OT network secure (IEC 62443)?

We design to IEC 62443 principles: segment the network into zones and conduits, keep IT and OT separated, use secure boot and signed firmware on edge devices, encrypt transport with TLS or OPC-UA security policies, and maintain a Software Bill of Materials. Because industrial equipment often can’t be patched on demand, we deliver a defensible, risk-based patch strategy rather than assuming downtime is available.

Why do IIoT pilots so often fail to scale?

The most common reason is that the pilot was never tied to a baseline KPI, so no one can prove it worked — and a project that can’t prove value never gets the capital to scale. Other frequent causes: choosing the hardest use case first, ignoring OT-security from day one, and underestimating SCADA/MES integration. We design the pilot specifically to produce an objective go/no-go decision.

Do you replace our SCADA or MES?

No. We integrate with what you run — Ignition, AVEVA/Wonderware, Kepware, OSIsoft PI, or a custom historian — using ISA-95 modelling so new IoT data is contextualized inside your existing systems. Ripping out working control systems is rarely the right move; adding a complementary data layer usually is.

Edge or cloud analytics — which is better?

It depends on latency, bandwidth, and connectivity. Time-critical anomaly detection and control belong at the edge (low latency, works offline); fleet-wide trending, model training, and reporting belong in the cloud. Most industrial deployments are hybrid: filter and react at the edge, aggregate and learn in the cloud. We design the split around your network reality.

What is the typical duration of an industrial project?

An instrumented pilot is usually 8 to 14 weeks. A connected-product firmware build for an OEM is typically 6 to 12 months depending on hardware and certification needs. Plant-wide rollout duration depends on site count and is scoped after the pilot validates the KPI.
