How to Integrate PLC/SCADA Data with Energy Analytics
Fast Answer
You can integrate PLC/SCADA data with energy analytics by connecting machine-level signals to an energy portal using protocols like Modbus TCP or OPC, enabling real-time monitoring and cost optimization.
Introduction
Manufacturers often ask: “Can I use my existing PLC or SCADA system to monitor energy?” The answer is yes—and doing so can unlock powerful insights. Here’s everything you need to know.
Q1: Why integrate PLC/SCADA with energy analytics?
Because your PLC already collects machine data. Adding energy metrics gives you visibility into cost per batch, downtime energy waste, and predictive maintenance opportunities.
Q2: How does integration work?
- Use Modbus TCP, OPC UA, or MQTT to share data from PLCs to your energy portal.
- Map tags for power, current, and runtime to analytics dashboards.
- Combine production data with energy usage for true cost-per-unit insights.
Q3: What equipment do I need?
- Existing PLC or SCADA system (Siemens, Allen-Bradley, Mitsubishi, etc.).
- Energy meters or LoRaWAN sensors for real-time consumption data.
- Gateway or middleware for protocol conversion if needed.
Q4: What are the benefits?
- Cost allocation: Know exactly which line or machine drives energy costs.
- Efficiency improvements: Spot idle energy waste during downtime.
- Compliance support: Generate SECR/ESOS-ready reports automatically.
Q5: Is it complicated to set up?
Not at all. Most modern PLCs support Modbus or OPC. With the right integration guide, setup can be completed in hours—not weeks.
