timer is 10 milliseconds to 1000 milliseconds. The default value for the watchdog timer is 200 milliseconds. The watchdog timer resets at the beginning of each sweep. The fail wait time is included in the watchdog check. The watchdog timer should be set to allow for the expected scan plus two fail wait times.

CPU Features

The CPU must reside in Slot 1 in rack 0, the main (CPU) rack. An illustration of the CPU 780 is shown in the following figure, followed by a description of the CPU features.
