A wastewater treatment plant use IOy Edge IO Modules to upgrade its outdated equipment monitoring system to enable real-time monitoring and remote control of flow rate and valve status.
Case Details
A municipal wastewater treatment plant needed to upgrade its outdated equipment monitoring system to enable real-time monitoring and remote control of key parameters such as flow rate and valve status. The goal was to improve operational efficiency and reduce manual inspection costs.
System Architecture
- Field Layer: BL190 Modbus TCP Edge I/O Module as the core controller
- Network Layer: BL190 connected to the plant's Ethernet industrial ring network
- Control Center: SCADA system (supporting Modbus TCP)
Hardware Configuration
- Host Model: BL190
- Expansion I/O Boards:
- Y31 (4-channel 4-20mA input module) for pH sensors
- Y13 (8-channel dry contact input module) for valve status monitoring
- Y22 (8-channel NPN output module) for valve control
- Y61 (4× RS485 module) for connecting multiple flow meters
System Features
- Real-Time Monitoring
- Remote Control
- Alarm Management
- Data Logging
System Advantages
- BL190 operates in -40°C to 85°C, suitable for humid environments
- 2KVrms isolation protection against electromagnetic interference
- 3 additional expansion slots for future sensors (turbidity, dissolved oxygen, etc.)
- Remote firmware updates via BLRAT tool
- Built-in web server for quick diagnostics
- Modular design for fast replacement of faulty components
- 30% lower hardware cost compared to traditional PLC solutions
- 50% reduction in field wiring effort
Thanks to BL190's edge computing capabilities, critical control logic runs locally, ensuring continuous operation even during network disruptions. This significantly improves system availability and safety.
