Automotive & Industry 4.0 Software

Software for the Connected Factory and Connected Vehicle

The automotive and manufacturing industries are undergoing a digital transformation that touches every part of the value chain. Production lines generate millions of data points per hour. Connected vehicles stream telemetry to cloud platforms. Supply chains span continents and require real-time visibility. Quality control increasingly relies on computer vision and machine learning.

But the software that manages all of this is often stuck in the past. Legacy SCADA systems with green-on-black terminals. Excel spreadsheets tracking production KPIs. Disconnected data silos that make it impossible to get a unified view of operations.

At proreactware, we build the modern web applications that sit on top of your industrial data. Real-time dashboards, production control interfaces, fleet management tools, and analytics platforms that turn raw data into actionable decisions.

Discover how a development subscription provides continuous development capacity for industrial software projects that evolve alongside your operations.

Core Challenges in Automotive and Industrial Software

Real-Time Data at Scale

A modern production line generates data from hundreds of sensors, PLCs, and controllers. A fleet of connected vehicles produces gigabytes of telemetry per day. The challenge is not collecting this data (your OT systems already do that) but making it accessible, visualizable, and actionable in real time.

Scale of data we handle:

Source	Data Volume	Latency Requirement	Protocol
PLC sensors	10,000+ data points/second	Sub-second	OPC UA, Modbus
Vehicle telemetry	1-50 MB/vehicle/hour	Near real-time (1-5s)	MQTT, HTTP
Quality cameras	10-100 MB/image	Near real-time	HTTP/gRPC
Environmental sensors	100-1,000 points/second	1-5 seconds	MQTT
Energy meters	1-10 points/second	5-15 seconds	Modbus, MQTT
MES/ERP events	Event-driven	Seconds to minutes	REST/webhooks

IT/OT Convergence

Industrial environments have a clear separation between IT (information technology: business systems, databases, web applications) and OT (operational technology: PLCs, SCADA, DCS). Building modern dashboards requires bridging this gap without compromising the safety and reliability of OT systems.

Our approach:

Read-only access to OT data through established gateways (OPC UA, MQTT brokers)
Edge computing for data preprocessing before cloud transmission
Network segmentation that keeps OT networks isolated
Protocol translation at the edge, not in the cloud
Fail-safe design where loss of the dashboard never affects production

Legacy System Integration

Automotive and manufacturing companies have decades of investment in existing systems: MES (Manufacturing Execution Systems), ERP (SAP, Oracle), PLM (Product Lifecycle Management), QMS (Quality Management Systems), and custom internal tools.

We do not replace these systems. We integrate with them, pulling data from APIs, databases, and message queues to create unified views that span multiple systems.

Architecture Patterns for Industrial Applications

Edge-to-Cloud Data Pipeline

Industrial data flows from sensors through edge devices to the cloud. We design data pipelines that handle this flow efficiently:

Edge layer: Data collection from PLCs and sensors via OPC UA or Modbus
Edge processing: Filtering, aggregation, and anomaly detection at the edge
Transport: MQTT or Kafka for reliable data transport to the cloud
Ingestion: Time-series database for raw data, relational database for events
Processing: Stream processing for real-time alerts, batch processing for analytics
Presentation: React dashboards with WebSocket updates for live data

Multi-Plant Architecture

Global manufacturers need dashboards that span multiple plants, time zones, and data sources. We build multi-plant architectures with:

Plant-level data aggregation with standardized schemas
Corporate-level dashboards with drill-down to individual plants
Role-based access control per plant, region, and function
Data normalization across different equipment and sensor types
Time zone handling for shift management across regions

Offline-Capable Applications

Factory floor environments do not always have reliable connectivity. We build progressive web applications (PWAs) that work offline:

Local data caching for recent sensor data and configurations
Offline form submission with sync when connectivity returns
Service workers for application availability without network
Conflict resolution for data entered offline by multiple users

Industry Standards and Protocols

We work with the standards and protocols common in automotive and manufacturing:

Standard/Protocol	Purpose	Our Experience
OPC UA	Machine-to-machine communication	Gateway integration for dashboard data
MQTT	Lightweight IoT messaging	Real-time sensor data transport
AMQP	Enterprise messaging	Integration with MES and ERP systems
VDA standards	German automotive quality	Quality dashboard implementations
IATF 16949	Automotive quality management	Quality data visualization and reporting
ISO 50001	Energy management	Energy monitoring dashboards
OEE (ISO 22400)	Equipment effectiveness	Production KPI dashboards

Why a Subscription Model Works for Industrial Software

Industrial software projects are inherently long-running. Production environments change, new equipment is added, new KPIs are needed, and regulations evolve. The traditional model of specifying a project, building it, and handing it over does not work when the requirements are continuously evolving.

A development subscription provides:

Continuous development as your operations evolve
Deep domain knowledge that accumulates over time
Predictable costs for IT budget planning
Flexibility to shift priorities between projects and plants

Subscription vs Full-time Hire: The challenge of hiring developers with industrial domain knowledge

Frequently Asked Questions

Do your developers have experience with industrial protocols?

Yes. Our senior engineers have experience integrating with OPC UA servers, MQTT brokers, Modbus devices, and various MES and ERP APIs. We build the web application layer that consumes data from these sources; we do not program PLCs or configure SCADA systems.

Can you connect to our existing SCADA or MES system?

Yes. We integrate with SCADA systems, MES platforms (Siemens Opcenter, Rockwell FTPC, MPDV, custom), and ERP systems (SAP, Oracle) through their APIs, databases, or message queues. Our API Development service covers these integrations.

How do you handle the security of connecting factory systems to web applications?

We follow IT/OT security best practices: read-only access to OT data through established gateways, network segmentation, encrypted communication, and fail-safe design. The web application never has direct access to control systems.

What about data volumes from thousands of sensors?

We design for high-throughput data ingestion using time-series databases (InfluxDB, TimescaleDB) that can handle millions of data points per second. Dashboard queries are optimized with pre-aggregation, materialized views, and intelligent caching.

Can you build mobile apps for factory floor use?

Yes. Our Mobile Development service includes native apps for iOS and Android. Factory floor apps are designed for rugged tablets with large touch targets, offline capability, and integration with barcode/QR scanners.

Do you support on-premise deployment?

Yes. While we typically deploy to cloud infrastructure, we understand that some industrial environments require on-premise or hybrid deployment. We containerize applications with Docker and Kubernetes for flexible deployment options.

How do you handle multiple time zones for global operations?

All data is stored in UTC. The frontend handles time zone conversion based on user preferences or plant location. Shift definitions, production schedules, and reporting periods are configurable per plant.
