2. AWS IoT SiteWise — Best Pay-As-You-Go IIoT

AWS IoT SiteWise is the most cost-transparent option in this guide. Its pay-as-you-go model charges per message ingested, per computation, per data point stored, and per monitor dashboard user — no platform fees, no minimums, no multi-year commitments. For plants that want to start a pilot without a six-figure purchase order, SiteWise removes the financial barrier. The platform collects data from OPC-UA servers, Modbus devices, and Ethernet/IP sources through the SiteWise Edge gateway (data collection pack is free). Asset models let you build equipment hierarchies and calculate metrics like OEE, uptime, and energy consumption. SiteWise Monitor provides no-code web portals for operations teams. The broader AWS ecosystem — Lambda, SageMaker, S3, Timestream — gives data teams powerful tools for advanced analytics and machine learning once the data is in the cloud. For maintenance teams, SiteWise can be configured to stream equipment condition data to Amazon SNS or SQS, which can then trigger work orders in connected CMMS platforms via API. AWS also offers IoT Events for rule-based alerting and anomaly detection through SiteWise's built-in ML capabilities. Best for: Plants already on AWS wanting transparent pricing, flexible scaling, and access to the full AWS analytics ecosystem. Pricing: Pay-as-you-go. Data ingestion: $1.00 per million messages. Computations: $0.20 per million. Data storage: $0.029 per GB/month. Edge data collection pack: free. Typical small-to-mid plant deployment: $500-$5,000/month depending on asset count and data frequency. Protocols: OPC-UA, Modbus TCP/RTU, Ethernet/IP via SiteWise Edge gateway Edge capability: SiteWise Edge with free data collection and paid data processing packs CMMS integration: Via AWS Lambda, SNS/SQS, or direct REST API to CMMS platforms

3. Microsoft Azure IoT — Best for Microsoft Ecosystem

Azure IoT is the natural choice for manufacturers running Microsoft infrastructure. IoT Hub handles device connectivity and message routing. Azure Digital Twins enables virtual modeling of physical plants and equipment. Azure IoT Edge pushes intelligence to the plant floor. And the entire stack connects natively to Power BI for real-time dashboards, Dynamics 365 for ERP and supply chain, and Azure AI for predictive analytics. The platform's unique strength is how seamlessly operational data flows into business systems. A vibration anomaly detected at the edge can trigger a Power Automate workflow that creates a work order in Dynamics 365, notifies the maintenance planner in Teams, and logs the event in Power BI — all within the Microsoft ecosystem. For maintenance and reliability teams already using Dynamics 365, Azure IoT provides the tightest integration between equipment condition data and maintenance management. For teams using standalone CMMS tools, Azure's REST APIs and event-driven architecture support integration with most modern platforms. Best for: Manufacturers in the Microsoft ecosystem wanting unified IoT, analytics, and business system integration. Pricing: Pay-as-you-go. IoT Hub: free tier available (8,000 messages/day), Standard tier starts at $25/month per unit (400,000 messages/day). Azure Digital Twins, Stream Analytics, and storage billed separately. Enterprise deployments scale from $1,000-$20,000+/month depending on message volume and services used. Protocols: MQTT, AMQP, HTTPS; OPC-UA via Azure IoT Edge modules Edge capability: Azure IoT Edge with containerized workloads, AI at the edge CMMS integration: Native with Dynamics 365 Asset Management; API-based with third-party CMMS

4. PTC ThingWorx — Best Enterprise IIoT Development Platform

ThingWorx is the most mature purpose-built IIoT development platform. With Kepware connectivity (supporting 150+ industrial protocols), rapid application development tools, built-in analytics, and Vuforia augmented reality integration, ThingWorx provides the most comprehensive toolkit for enterprises building custom IIoT solutions. Gartner has recognized PTC as a Visionary in Industrial IoT for two consecutive years. Important context: In late 2025, PTC announced the sale of ThingWorx and Kepware to private equity firm TPG for up to $725 million. The deal is expected to close in the first half of 2026. TPG also acquired GE Vernova's Proficy manufacturing software business, signaling an intent to build a consolidated industrial software portfolio. Existing ThingWorx customers should experience business as usual in the near term, but the ownership transition introduces uncertainty around long-term roadmap and support. For maintenance teams, ThingWorx's asset monitoring and predictive analytics capabilities are strong — remote condition monitoring, anomaly detection, and threshold-based alerting are core use cases. Kepware's protocol breadth means it can connect to virtually any equipment on the plant floor, regardless of vendor or vintage. Best for: Large enterprises building custom IIoT applications that need the broadest protocol support and a full development platform. Pricing: Custom, not published publicly. Named-user and device-based licensing. Industry benchmarks suggest mid-size deployments start at $100,000+/year. Enterprise deployments with Kepware, analytics, and Vuforia can reach $500,000+/year. Protocols: 150+ via Kepware (the broadest in the industry) Edge capability: ThingWorx Edge with local compute and store-and-forward CMMS integration: ThingWorx Flow connects to SAP, Salesforce, and other enterprise systems; REST API for CMMS platforms. Now also part of Rockwell FactoryTalk ecosystem.

5. Rockwell Automation FactoryTalk — Best for Allen-Bradley Plants

FactoryTalk is Rockwell Automation's software suite spanning MES, analytics, IIoT, and edge computing. For plants running Allen-Bradley PLCs and Rockwell automation, FactoryTalk provides the most direct path from controller data to actionable insights. FactoryTalk Optix delivers modern HMI and visualization. FactoryTalk Analytics LogixAI embeds anomaly detection directly into the control layer. FactoryTalk Hub provides cloud-based analytics and remote monitoring. Rockwell's 2023 integration of PTC ThingWorx into the FactoryTalk ecosystem (branded as FactoryTalk InnovationSuite) added IIoT development capabilities and Kepware connectivity to the portfolio. With Fiix CMMS also in the Rockwell portfolio, there's a natural integration path from equipment monitoring through maintenance execution — though in practice, these products are still somewhat siloed and integration requires configuration. For maintenance teams in Rockwell-heavy plants, FactoryTalk + Fiix represents the most vertically integrated OT-to-maintenance stack from a single vendor. Best for: Plants running Allen-Bradley PLCs and Rockwell automation wanting native OT connectivity and a path to maintenance integration through Fiix CMMS. Pricing: Custom, based on modules and scale. Sold through Rockwell distributors and partners. Typical deployments start at $25,000-$100,000+ depending on modules selected. Protocols: Native EtherNet/IP and Allen-Bradley connectivity; OPC-UA and 150+ protocols via Kepware/ThingWorx Edge capability: FactoryTalk Edge Gateway, LogixAI embedded in controllers CMMS integration: Fiix CMMS (Rockwell-owned); API-based integration with other CMMS platforms

6. GE Vernova Proficy — Best for Process and Heavy Industry

GE's industrial software portfolio — now under the GE Vernova brand — includes Proficy Historian (one of the most widely deployed industrial historians), Proficy SCADA (iFIX and CIMPLICITY), and Proficy Manufacturing Execution Systems. For process industries (oil and gas, chemicals, power generation, water treatment) where SCADA, historian, and MES infrastructure are critical, Proficy provides enterprise-grade data infrastructure that most IIoT-native platforms cannot match. Note: GE Vernova sold the Proficy business to TPG in late 2025, the same private equity firm acquiring PTC's ThingWorx and Kepware. This consolidation under TPG could create a powerful integrated industrial software platform, but the long-term product roadmap is still developing. For maintenance teams in heavy industries, Proficy's historian and analytics capabilities provide the deep historical trending and process data analysis needed for reliability engineering — failure pattern identification, process correlation analysis, and long-term equipment health tracking. Best for: Process and heavy industries with existing SCADA/historian infrastructure needing enterprise-grade industrial data management. Pricing: Custom, based on tag count and modules. Historian pricing scales with the number of data tags. Contact vendor or authorized distributor for quotes. Protocols: OPC-UA, OPC-DA, native GE controller connectivity, Modbus, MQTT Edge capability: Proficy Edge with on-premise historian and analytics CMMS integration: API-based; commonly integrated with SAP PM, Maximo, and other enterprise asset management platforms

7. Litmus Edge — Best Vendor-Neutral Edge Platform

Litmus takes a fundamentally different approach than the other platforms on this list. Rather than trying to be an end-to-end IIoT solution, Litmus focuses on the hardest part of industrial IoT: getting data off heterogeneous plant floor equipment and making it available to any cloud, analytics, or business system. With support for 250+ industrial protocols and pre-built connectors for AWS, Azure, GCP, SAP, and other platforms, Litmus eliminates vendor lock-in at the connectivity layer. The platform runs on edge hardware at the plant, collecting data from PLCs, CNCs, robots, sensors, and legacy equipment regardless of vendor. Data is normalized, contextualized, and can be routed to any destination — cloud platforms, on-premise historians, data lakes, or directly to CMMS and ERP systems. For maintenance teams, Litmus's value is in unlocking equipment data that was previously trapped in proprietary systems. Once data flows through Litmus, it can feed condition monitoring analytics, trigger CMMS work orders, and support predictive maintenance programs regardless of which cloud or software stack the organization runs. Best for: Plants with mixed-vendor OT equipment wanting to avoid cloud lock-in while connecting legacy and modern assets to any analytics platform. Pricing: Per-gateway licensing model. Pricing is not published publicly — contact vendor for quotes. Pilot programs available. Protocols: 250+ industrial protocols (the broadest native support among edge platforms) Edge capability: Edge-native architecture with containerized applications, local analytics, and store-and-forward CMMS integration: API-based; connects to any CMMS via REST API or middleware

2. What's your cloud strategy? If already on AWS, SiteWise fits naturally. If Microsoft, Azure IoT. If no cloud preference, evaluate based on use case rather than cloud provider.

3. Do you want to build or buy? ThingWorx and Azure IoT are development platforms — powerful but require engineering resources. Insights Hub and FactoryTalk offer more out-of-box applications. Litmus focuses specifically on connectivity.

4. What's your primary use case? For condition monitoring and predictive maintenance, evaluate how easily the platform integrates with your CMMS. For OEE and production analytics, evaluate built-in manufacturing KPI dashboards. For energy management, evaluate metering and reporting capabilities.

5. Start with a pilot. Every platform listed here supports focused pilot deployments. Start with 5-10 critical assets, prove value in 90 days, then scale.

How Industrial IoT Connects to Maintenance and Reliability

For maintenance and reliability professionals, IIoT is the technology layer that enables the shift from calendar-based preventive maintenance to condition-based and predictive maintenance. Here's how the integration works in practice:

• Data collection: Sensors on equipment (vibration, temperature, pressure, current, ultrasound) feed data to the IIoT platform through edge gateways or direct cloud connectivity.

• Edge processing: The edge gateway filters noise, aggregates data, and runs first-level analytics — baseline comparisons, threshold checks, and anomaly detection — before sending summarized data to the cloud.

• Cloud analytics: Advanced analytics and machine learning models identify degradation patterns, predict remaining useful life, and flag assets requiring attention.

• CMMS integration: When an alert or prediction triggers, the IIoT platform creates or updates a work order in the CMMS with the equipment ID, diagnosis, recommended action, and supporting data. The maintenance planner reviews and schedules the work.

• Feedback loop: Maintenance completion data from the CMMS feeds back into the analytics models, improving prediction accuracy over time.

The key evaluation question for maintenance teams: how easily does this platform create a work order in my CMMS when it detects a problem? The fewer manual steps in that loop, the more value the IIoT investment delivers.
