Zwatchdog timer is a single-width camac module providing a safety interlock input and a mechanism that determines network or computer failure in complex control or data acquisition systems. Once configured for a specific application and enabled by a controlling processor, the watchdog's warning features remain armed as long as there is dataway traffic within the selected timeout period, is used with modules that can be disabled by dataway inhibit (i), a known, well-defined shutdown state is guaranteed if the system fails. Optionally, the relay outputs can be included in safety interlock chains programmable controller inputs, or remote interrupts for automatic shutdown logic; both timeout and power monitor outputs may be used in this way
