8-8 Communicating with Devices on a DeviceNet Link

The rack-optimized connection creates a DINT element for mapped data for

each DeviceNet module connected to the card “dnet.” The array dnet:I.Data

contains the possible input elements; the dnet.O.Data contains the possible

output elements.

The index number on the array element refers to the same numbered word

mapped to the device in RSNetWorx for DeviceNet. Depending on the device,

there can be several words mapped to on device. You can create aliases to the

elements you actually use to more identify the data you need.
