CMMS and IIoT supervision: How to connect your maintenance tools to industrial monitoring
Thomas Peyron
•
CMMS (Computerized Maintenance Management System) and IIoT monitoring are two complementary tools that, in most factories, still operate in silos. The CMMS manages work orders, intervention histories, and spare parts inventory. An industrial IIoT platform collects and analyzes field data in real time. Each performs its function well, but operating separately, they miss out on substantial value.
Connecting the two means shifting from reactive maintenance to data-driven maintenance: field alerts that automatically trigger work orders (WO), intervention histories that enrich anomaly detection models, and availability indicators calculated from actual field conditions rather than manual reporting.
The Silo Problem Between CMMS and Monitoring
In traditional industrial organizations, maintenance managers run their CMMS based on available information: manual intervention reports, scheduled field rounds, and breakdown histories. Real-time monitoring continuously generates equipment status data, but this data is not automatically integrated into the CMMS.
As a result, preventive maintenance WOs are triggered on fixed schedules regardless of actual equipment condition, unanticipated breakdowns occur that could have been predicted with available data, and technicians arrive at interventions without knowing the context of the equipment's recent operating hours. This is precisely the type of system fragmentation we detail in our article on connected industry and its technical challenges.
What the CMMS / IIoT Connection Enables
Triggering WOs on Field Alerts
When DAT'Power or DAT'Process detects an anomaly—an IPE drift, exceeding a vibration threshold, abnormal motor behavior—the alert can automatically trigger a work order in the CMMS. There is no need to wait for the next day's rounds: the maintenance team is notified in real time, with the contextual data of the anomaly. We demonstrated this alert mechanism in action in our article on compressed air leaks in industry, where DAT'Power quantifies each drift in €/day to prioritize interventions.
Enriching CMMS History with Field Data
Conversely, when a technician closes a WO in the CMMS (part replacement, adjustment, cleaning), this information can be transmitted to the IIoT platform to contextualize the data. The post-intervention consumption curve is compared to the pre-intervention curve to validate the effectiveness of the action—a principle that directly aligns with our industrial metering plan methodology: a gain can only be validated if it has been previously measured.
Calculating Availability and Performance Indicators
Combining field status data and CMMS data allows for the calculation of reliable indicators: actual availability rate, MTBF, and MTTR. These KPIs are not self-reported; they are calculated from objective data and displayed in dashboards customized by profile (maintenance manager, production manager, management). For a deeper look at the value of field data applied to energy and operational performance, our article on the benefits of IIoT for energy management details nine concrete levers.

Technical Gateways: How It Works
CMMS / IIoT integration relies on bidirectional data exchanges via APIs or dedicated connectors. The general principle:
The IIoT platform exposes its alerts and data via a REST API or a message broker (MQTT, webhooks).
The CMMS receives these events and automatically creates the corresponding WOs, complete with contextual information.
Upon closing a WO, the CMMS sends the intervention details back to the IIoT platform.
This architecture is non-intrusive: it does not alter the internal operation of the CMMS and does not require changes to existing business configurations. These sensitive data exchanges (equipment status, intervention histories) naturally fit within the security framework detailed on our industrial cybersecurity page, managed with N-CyP for projects requiring comprehensive cybersecurity support.
The DATIVE × DIMO Maint Example
DATIVE has structured this approach with DIMO Maint, one of the leading French industrial CMMS providers. The DAT'Process / DIMO Maint integration allows field status data to flow to the CMMS and automatically trigger WOs based on defined thresholds.
Together, we have formalized this approach in a dedicated e-book, which details the methodology, use cases, and success conditions of a data-driven maintenance project.

Conditions for Success in a CMMS / IIoT Integration Project
Clearly define which alerts should trigger WOs: not every alert warrants an immediate intervention.
Train maintenance teams to interpret contextualized IIoT data within the CMMS.
Align equipment taxonomies between the CMMS and the IIoT platform (common identifiers)—a fundamental task we address in connected industry: meeting technical challenges.
Define WO closure processes to ensure return data is structured and usable.
What Changes for Field Teams
Technicians working with CMMS / IIoT integration describe a concrete change in their daily routines: they rarely work blind. Before an intervention, they consult the last 48 hours of field data for the relevant equipment in the CMMS. After an intervention, they quickly verify if their action had the expected effect on the indicators—a reliability logic that aligns with our case study on energy management in HVAC industries with DAT'Power, where centralized hypervision directly improved the responsiveness of maintenance and energy teams.
For maintenance managers, manual indicator calculations are eliminated: availability and performance KPIs are continuously available without manual entry. This approach applies to sensitive environments—as shown in our case study on DAT'Power deployment at a high-threshold SEVESO site—as well as machine fleets with DAT'Machine or mountain infrastructure with DAT'Mountain.
