Configured 1769-ADN

Powerup Behavior

On powerup, the 1769-ADN, with a previous valid configuration, will

compare the saved system keying configuration with the actual

devices to determine if all of the keys match the actual devices (as

defined in the Comparison Feature section on page 4-29).

If they match, the 1769-ADN will complete the configuration of all I/O

modules and then wait for a DeviceNet master/scanner to make a

connection. If any of the keys do not match, the 1769-ADN will not

permit a DeviceNet master/scanner to make an I/O connection and

will wait for a valid configuration.
