RAP Systems SCADA Reporting
01 Overview
RAP Systems needed a way to turn raw SCADA and production data into reliable, scheduled reports without manual intervention. We built an n8n-driven automation layer that orchestrates the full reporting pipeline: collecting data from their SCADA server via OPC-UA, transforming it in a FastAPI/Python backend connected to Microsoft SQL Server, and triggering report generation automatically based on shift schedules or manual requests from a React frontend. n8n handles the workflow logic—scheduling, conditional triggers, PDF report delivery, and error notifications—while the underlying stack (FastAPI, SQL Server, Docker) manages data and rendering. The result is a hands-free traceability and compliance system that generates reports on demand or on schedule, covering full production-line traceability by lot number, ingredient, or recipe.

02 Challenges
- Manual, time-consuming report generation from SCADA data
- No automated scheduling or triggering for compliance reports
- Complex traceability requirements across multiple production variables
- Bridging legacy SCADA infrastructure with modern workflow automation
- Delivering reports reliably with error handling and notifications
03 Solutions
- Built an n8n automation layer to orchestrate the full reporting pipeline end-to-end
- Connected SCADA Server via OPC-UA into n8n-triggered workflows for real-time data ingestion
- Implemented automated and manual report triggers with n8n conditional logic
- Integrated PDF report generation and delivery directly into n8n workflow steps
- Added error-handling and alert notifications within n8n for reliable, monitored automation
