Configuring Your Compact
I/O System Online If your 1769 I/O system physically exists, you’ll save time by
configuring the Compact I/O system online. By configuring online,
you simply upload the entire I/O layout including end caps, cables,
and power supplies. Then, you only need to modify the configuration
parameters for each I/O module and re-save (download) the final
configuration back to the Series A 1769-ADN adapter.
Online configuration is completed in the same way as the offline
configuration with the addition of the following features:
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 3-22 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 A adapter configuration and the configuration of
all of the 1769 devices.
