IoT Integration and Machine Monitoring Software
Your machines generate data. Most manufacturers either can't capture it or can't act on it. IoT integration closes that gap -- connecting your equipment to a central platform so you can see machine uptime, cycle time, and OEE in real time from any device.
We connect PLCs, SCADA systems, and industrial sensors via OPC-UA, MQTT, and Modbus TCP to custom monitoring dashboards, downtime alerting, and the data pipelines that power predictive maintenance and Industry 4.0 initiatives.

RaftLabs builds custom IoT integration and machine monitoring software for manufacturers -- connecting PLCs, SCADA systems, and industrial sensors via OPC-UA, MQTT, and Modbus TCP to real-time OEE dashboards, downtime tracking tools, and predictive maintenance data pipelines. The software gives plant managers and maintenance teams live visibility into machine availability, cycle time, and performance without manual data collection. Most IoT monitoring projects deploy in 10 to 16 weeks at a fixed cost.

The data is already there -- the problem is capturing it
Modern manufacturing equipment generates more data than most plants know what to do with. PLCs log cycle counts, fault codes, and run states. Sensors measure temperature, vibration, pressure, and energy draw. SCADA systems record process variables by the second. Almost none of that data reaches the people who could act on it. It stays in the machine controller, overwritten by the next shift, never analysed.
The gap between the data your machines produce and the decisions your managers can make is an operational and financial problem. Every hour of unplanned downtime that could have been predicted, every OEE calculation done on a spreadsheet the morning after the shift, every energy anomaly that ran for weeks unnoticed -- these have a cost. IoT integration doesn't add sensors to your machines. It connects what already exists to a system that makes the data usable.
We work with your engineering team to understand your existing equipment, protocols, and network topology. We design the integration layer to fit your environment -- edge computing where bandwidth or latency makes cloud-first impractical, direct connectivity where the infrastructure allows it. The result is a monitoring platform your operations and maintenance teams can act from, not just observe.
What we build
PLC and SCADA connectivity
We connect to your industrial equipment using OPC-UA, MQTT, Modbus TCP, and REST APIs where available. Data normalisation converts signals from heterogeneous machine protocols -- different PLCs, different vintages, different manufacturers -- into a single consistent data model that feeds your monitoring platform. For environments where bandwidth is constrained or where cloud latency would affect real-time response, we design edge computing nodes that process and buffer data locally before uploading to the central system. Older machines without digital interfaces can be monitored via low-cost I/O modules attached to existing machine signals such as cycle complete relays or motor run contacts.
Real-time OEE dashboards
Overall Equipment Effectiveness is calculated continuously for each machine, production line, and shift -- availability multiplied by performance multiplied by quality -- using live data from your PLCs and operator inputs, not from manual shift reports. Supervisors see a live floor view showing which machines are running, idling, or in downtime. Plant managers get shift and daily production summaries with trend lines. The dashboards are accessible on any device so visibility isn't tied to a control room screen. Targets and benchmarks are configurable per machine so performance is measured against what that specific asset should produce.
Downtime tracking and alerting
Downtime events are detected automatically from machine signals -- no operator action needed to start the clock. When a machine stops, operators are prompted on a shop floor terminal to record the reason code: planned maintenance, unplanned breakdown, material shortage, changeover, or a category specific to your operation. Mean time between failures and mean time to repair are calculated from this data per machine and per failure mode. Alert thresholds are configurable -- SMS and email notifications go to the right people when a machine has been down longer than the defined threshold, when a shift's downtime rate crosses a target, or when a specific failure code recurs.
Predictive maintenance integration
The condition data captured by IoT monitoring is the foundation of predictive maintenance. We build trend monitoring for the parameters that indicate equipment degradation -- vibration amplitude, bearing temperature, motor current draw, cycle time drift, and pressure variance. When measured values approach the threshold that historically precedes a failure, the system raises an alert and, where your CMMS supports it, creates a work order automatically. Integration with SAP PM, IBM Maximo, Infor EAM, UpKeep, and custom maintenance management systems means the right maintenance action is triggered without a manual step between the alert and the work order.
Energy and utilities monitoring
Electricity, gas, water, and compressed air consumption monitored per machine and per production area. Energy cost is allocated by product and shift so you can see the energy cost contribution to each product's unit cost, not just a plant-wide utility bill. Consumption anomaly detection identifies equipment drawing more power than normal during a production run -- a motor running hot, a compressed air leak, or a heating element that's lost efficiency. Alerts go to the maintenance team before the anomaly becomes a breakdown or a quality problem. Shift-level energy reports give production managers data to act on, not just an end-of-month utility invoice.
Multi-site monitoring and reporting
Consolidated OEE, downtime, and energy reporting across multiple plants in a single platform. Site comparison dashboards let operations directors see which plants are performing above target and which need attention, without waiting for site managers to compile and submit weekly reports. Centralised alert management routes notifications by site with local escalation paths so the right people at each plant are alerted for their own equipment. Inter-site benchmarking of machine availability and cycle time gives your engineering team data to identify best practices at one plant and apply them at others.
Frequently asked questions
We work with OPC-UA, MQTT, Modbus TCP, and REST APIs as the primary connectivity methods. OPC-UA is the preferred protocol for modern industrial equipment as it carries rich metadata alongside process values. MQTT works well for high-frequency sensor data and constrained network environments. Modbus TCP covers the large installed base of older PLCs and drives. For machines that pre-date digital interfaces, we assess whether signals such as motor run status, cycle complete, or fault relay outputs are accessible and design an I/O bridge accordingly. We document the connectivity approach for every machine type during the discovery phase so there are no integration surprises during build.
Overall Equipment Effectiveness is the product of three factors: availability, performance, and quality. Availability is the proportion of scheduled production time that the machine was actually running -- planned downtime and unplanned breakdowns both reduce it. Performance is the ratio of actual cycle time to ideal cycle time -- slow running reduces it even when the machine is technically available. Quality is the proportion of output that meets specification first time -- rework and scrap reduce it. OEE combines these three factors into a single percentage that reflects how effectively a machine is being used relative to its theoretical maximum. The software calculates each component from live machine signals and operator inputs rather than from manual shift reports, so the number is current and accurate.
IoT monitoring provides the data layer that predictive maintenance models run on. Without a reliable stream of condition data -- vibration readings, temperature trends, cycle time measurements, power draw -- predictive maintenance is guesswork. The monitoring platform we build captures and stores this time-series data per machine. Predictive models are then trained on historical data from that platform to identify the patterns that precede specific failure modes. Once trained, the models run against the live data stream and flag when a machine's condition is trending toward failure. The monitoring platform is both the data source for model training and the delivery mechanism for predictive alerts. Building it correctly from the start determines how effective predictive maintenance can eventually become.
An initial deployment covering connectivity, OEE dashboards, downtime tracking, and alerting for a single plant typically runs $25,000 to $60,000 depending on the number of machines, the mix of protocols involved, and whether edge computing infrastructure is needed. Plants with a small number of machines on a common protocol sit at the lower end. Plants with many machines across multiple protocol types, or where edge nodes are needed for network topology reasons, sit higher. Multi-site expansion after the initial plant is lower cost per site as the platform infrastructure is already in place. We scope every project before pricing it, with a fixed project cost rather than hourly billing.
