A template-driven system for decoding industrial device registers (Modbus/OPC-UA) and routing data to Unified Namespace architectures.

In Simple Terms: This project reads data from industrial devices (power meters, PLCs, sensors) and makes sense of it. Instead of seeing raw binary numbers, you get:

• "Temperature: 23.5°C, Health: Good"
• "Alarm: High Voltage on Phase A, Priority: Critical"
• "Manufacturing Date: 2024-03-15"

Then it routes this meaningful data to the right places in your industrial data infrastructure.
