mode (CommandRegister.Run is 1) in the scanner control output
word = 0.
The scanner status should display only the node address of the scanner.

IMPORTANT
When setting the AutoScan mode from Disable to Enable, the
1769-SDN scanner clears all existing configuration.
IMPORTANT
With 193-DNCT terminal, version 2.1 and higher, the
active nodes line on the Network Who screen should
show a number that exactly matches how many slave
devices are on the DeviceNet network.
If the number on the active nodes line doe not match the
number of slave devices on the network, the cause
typically is one of the following:
• The consume I/O data size of a device is greater than the
selected I/O allocation size.
• The slave device is not on the network.
