Connections to DeviceNet devices

In this example the controller uses two connections (one for status and one for

I/O) to communicate with the DeviceNet devices through the 1788-DNBO

module. The 1788-DNBO module uses a rack-optimized connection to the

DeviceNet devices.

The following table calculates the connections in this example.

The 1788-DNBO card does not establish connections to its devices; and

therefore, the controller does not establish connections with DeviceNet

devices. The 1788-DNBO module acts as a scanner that gathers all the data

from its devices and packs that data together into one image that is passed to
