How does the watchdog function in EC32/EC60 RTU achieve automatic fault recovery?

EC32/EC60 RTU remote terminals feature dual hardware and software watchdog automatic recovery mechanisms to ensure 24/7 stable operation of water monitoring systems. When system crashes or anomalies occur, the watchdog function automatically detects and restores normal device operation.

• Hardware Watchdog: Independent hardware circuits monitor main CPU status with fast response times
• Software Watchdog: Multi-level software monitoring mechanisms detect program anomalies and infinite loops
• Automatic Restart: Executes system restart automatically upon anomaly detection without manual intervention
• Fault Logging: Records watchdog trigger times and causes for fault analysis
• Tiered Protection: Different recovery strategies based on fault severity levels
• Communication Monitoring: Monitors 4G communication module status with automatic reconnection during communication failures

This function is particularly suitable for remote LGF electromagnetic flow meter and HZ-KSLF radar flow meter data acquisition, significantly reducing on-site maintenance frequency and improving system reliability. After watchdog recovery, status reports are automatically sent to the monitoring center.
