Streamlining equipment maintenance operations is possible! Introducing the solutions of the 'ST Series products.'
The "Device Self-Monitoring Function (WDT)" is a feature that monitors whether the main devices inside the equipment are operating normally. If an anomaly is detected, the device is automatically reset to recover from the abnormal state. The device self-monitoring function is designed with a fail-safe mechanism that can detect anomalies even when the CPU has stopped. Minor system anomalies that occur in unmanned equipment, such as roadside cameras, are automatically recovered, allowing for labor-saving in equipment maintenance tasks. 【Target Devices】 ■ST13528M ■ST13512M ■ST13520 ■ST13116M ■ST13512PW・ST13518PW ■ST13908M ■ST12500M *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Device Self-Monitoring Function Processing】 1. The CPU periodically accesses the main IC to perform status monitoring. 2. Responds to accesses from the CPU. In case of an anomaly, it either does not respond or displays internal parameter anomalies. 3. When both the main IC and the CPU are normal, the internal counter of the reset IC is reset. If an anomaly in the main IC is detected, the internal counter of the reset IC continues to count up (if the CPU itself is abnormal, it cannot execute the counter reset process). 4. The internal counter is reset by the counter reset from the CPU, allowing the device to continue operation. If there is no counter reset from the CPU, the internal counter will reach a threshold and execute a device reset. *For more details, please refer to the PDF document or feel free to contact us.
