Application Scenario
In large-scale breweries, precise temperature and process control is essential for consistent flavor and product quality. This application demonstrates how the ARMxy industrial controller, combined with OpenPLC, enables intelligent automation of a beer fermentation tank.
System Configuration
ARMxy Controller for central logic and communication
Y-AI Analog Input Module to monitor fermentation parameters
Y-AO Analog Output Module to control refrigerant valves
Implementation Details
The Y-AI module captures:
• PT100 temperature signals (3-wire configuration)
• Brix/dissolved sugar levels via an online refractometer (4–20mA)
The system performs multi-stage cooling, precisely following a fermentation curve (e.g., 12°C gradually reduced to –1°C)
OpenPLC handles all logic and timing, including the generation of fermentation trend curves
During fermentation, parameters such as phase durations and control setpoints can be remotely updated through BLRAT, allowing the OpenPLC logic to adapt on the fly
Advantages
✔️ Remote recipe tuning via mobile app for brewmasters
✔️ Valve position feedback supported by Y-Series AO modules for fine control
✔️ Ensures consistent quality through repeatable, programmable fermentation profiles
This flexible and scalable system brings digital transformation to the traditional brewing process, helping breweries optimize efficiency and quality.
