Configuring the 1769-ADN Series B Adapter
The 1769-ADN must be configured with RSNetWorx for DeviceNet software. This
configuration tool allows you to identify all of the devices (I/O modules, power supplies,
expansion cables, end caps) and their locations in your 1769 system. The 1769-ADN must have
the I/O configuration loaded into its’ memory to perform the network communication
function.
The 1769-ADN does not accept I/O connections if the programmed system configuration does
not match the actual system configuration. The 1769-ADN retains the programmed system
configuration in non-volatile memory so it can compare it with the actual system configuration
on power-up. For more information, refer to the Compact I/O 1769-ADN DeviceNet Adapter User

* = The amount of output data for each module is based on the configuration of each I/O module done as part of the 1769-ADN
configuration. Note that if an I/O module is configured to have 0 words of output data, then there are no output data words for that
module in the 1769-ADN’s output image.
