The board APCI-035 is equipped with 4 watchdogs which can monitor software and hardware tasks independently from each other. Watchdog 1 works with 2 alarm levels and can be programmed with 1 of 4 different time units (µs, ms, s, min). In case of error, watchdog 1 warns the PC or the peripheral.
If the error is not removed, the alarm level 2 is automatically triggered after a defined timeout and prepares the system and the peripheral for a hardware reset.
The alarm levels are controlled through 1 trigger channel and 4 different time bases. The internal PC temperature can be monitored through the onboard temperature sensor.
