watchdog timer
An error-checking system that examines the processor state, software timers, and program-
related counters when the CRBasic program is running. The following will cause watchdog
timer resets, which reset the processor and CRBasic program execution: processor bombed,
processor neglecting standard system updates, counters are outside the limits, voltage
surges, and voltage transients. When a reset occurs, a counter is incremented in the
WatchdogTimer entry of the Status table. A low number (1 to 10) of watchdog timer resets is
of concern, but normally indicates that the situation should just be monitored. A large
number of errors (>10) accumulating over a short period indicates a hardware or software
problem. Consult with a Campbell Scientific support engineer.
