About this app

Turn your smartphone into a powerful Industrial Modbus RTU Master! Modbus RTU Station is a premium communication tool specifically designed for field maintenance engineers, System Integration (SI) experts, and hardware developers. No more carrying heavy, battery-draining laptops to cramped server rooms or up high ladders. With just your smartphone and a USB OTG cable, you can instantly check data, change values, and debug equipment on-site.
🔥 Key Differentiators:
• Laptop-Free Mobility: No need to open a laptop in precarious field conditions. Debugging is now as simple as taking out your phone.
• Rock-Solid Stability: Optimized with the usb_serial package to ensure stable communication with various USB-to-RS485/232 converters.
• Expert-Grade Settings: Supports detailed serial parameters (Baud Rate, Data Bits, Stop Bits, Parity) to handle any legacy equipment.
• Android-Exclusive Optimization: Strategically developed only for Android to provide deep hardware integration that iOS cannot offer.
🛠 Main Features:
• Comprehensive Function Code Support: Full support for FC01 (Coil), FC02 (Discrete Input), FC03 (Holding Register), and FC04 (Input Register).
• Built-in CRC-16 Logic: Features a high-reliability Modbus RTU standard CRC-16 checksum engine for accurate data transmission.
• Versatile Data Formats: Visualize data in Binary, Int, Hex, Float, or Double formats.
• Advanced Data Handling: Provides Word Swap (Inverse/Byte Swap) options for complex communication environments.
• Real-time Monitoring & Control: High polling speeds allow for real-time surveillance and immediate Write commands.
💎 Premium (Pro) Benefits ($19.99):
• Unlimited Profile Saving: Save the connection info and register settings for frequently used devices and load them anytime.
• Ad-Free Environment: Work in a clean, professional environment without any interruptions during critical inspections.
• Enhanced Security: A pure on-device tool that never sends your data to external servers, ensuring industrial confidentiality.
⚠️ Requirements & Important Notes:
• Recommended OS: Android 9 (Pie) or higher is strongly recommended for stable USB driver performance and communication.
• Hardware Requirements: A USB OTG adapter and a Serial converter cable (RS485/232) are required to connect to your devices.
• Device Compatibility: Please ensure your smartphone supports USB Host mode (OTG) before purchasing.
