4-28 Configuring Your Compact I/O Series B DeviceNet Adapter
Apply/OK Button
When you choose Apply or OK, the software downloads the
configuration of the desired devices to the 1769-ADN if the key check
on the system keying configuration has passed.
If the downloaded system keying configuration (the configuration that
identifies all the devices present, their location, and keying option)
does not match the keys of the actual 1769 devices, the 1769-ADN
will reject all downloaded configuration and you’ll see an error
message. You’ll then need to return to the appropriate section of the
configuration tool and make your changes or change the actual
hardware/device on the 1769 bus.
Refer to the Comparison Feature section on page 4-29 for more
information on matching system keying configuration and keys of the
actual 1769 devices. The 1769-ADN will not accept I/O connections
from any scanner until the system keying configuration is successfully
downloaded.
Once all configuration is successfully downloaded, RSNetworx has the
1769-ADN save all the configuration in non-volatile memory. This
includes the Series B adapter configuration and the configuration of
all of the 1769 devices.
