SCANport Command
Reference
For applications where a digital communications network interface is
the preferred interface, one of the Allen-Bradley 1200 series SCANport
adapter modules must be used. Regardless of the control network the
method of passing data to and from the drive is the same. Figure 4.2
illustrates the nature of the data exchanged. The illustration uses
DeviceNet as an example of a open communication network.
