10 Application Example on Constructing DeviceNet Network

In this section, we will present an application example, illustrating how to construct a DeviceNet network and the

configuration of the network.

Target Using an X point of DVP28SV to control RUN/STOP of the remote VFD-L AC motor drive.

10.1 How to Construct a DeviceNet Network

1) The connection
