ARMxy+OpenPLC+HMI is designed for batch process control in industries such as chemicals, petroleum, and pharmaceuticals.
Case Details
This setup is designed for batch process control in industries such as chemicals, petroleum, and pharmaceuticals. Typical applications include:
- Reactor (Reaction Vessel) Control – Temperature, pressure, stirring speed, and ingredient dosing.
- Pipeline Flow Monitoring – Real-time flow measurement and control of liquids/gases.
- Batch Production Management – Tracking and logging each production batch for traceability and compliance.
System Architecture
ARMxy SBC: Central controller running OpenPLC runtime and Node-RED for logic and data processing.
OpenPLC: IEC 61131-3 compliant PLC software for industrial control logic.
HMI (Touch Panel): Graphical interface for operators to monitor and interact with the process.
I/O Modules: Y-series boards for analog I/O (temperature, pressure, flow) and digital I/O (valves, pumps).
Cloud/SCADA: Optional integration via MQTT or OPC UA for remote monitoring and data historization.
Key Functions
- Visualization of Process Flow
- PID Diagrams: Real-time process diagrams showing valves, pumps, sensors, and reactors.
- Trend Curves: Live and historical trends for temperature, pressure, flow rate, etc.
- HMI Screens: Built with Qt or web-based interfaces, accessible locally or remotely.
- Leak detection (via pressure drop or flow anomaly)
- Overpressure or underpressure alerts
- Temperature excursions beyond setpoints
- Audible and visual alarms on HMI and via email/SMS
- Data Logging and Compliance
- Records all critical process parameters (time, temperature, pressure, flow, operator actions)
- Exportable reports for FDA, GMP, ISO compliance
- Secure storage and audit trails
Benefits
- Unified Platform: ARMxy integrates control, HMI, and data logging in one device.
- Flexibility: Customizable I/O and software stack.
- Compliance Ready: Built-in data logging and secure access.
- Remote Access: BLRAT allows remote maintenance and updates.
