5 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. Before constructing a network, you have to first know clearly what the network is for and start a preliminary planning for the data to be exchanged. The plan shall include the maximum communication distance, slaves to be used, total length of data to be exchanged and so on. These information will decide whether the network you construct is a reasonable one, or if it satisfies your needs, and even affect the later-on network sustainability and flexibility of network capacity upgrade.
