Hi ian,
Try

http://www.odva.org

it is the official DeviceNET website, they have some documentation in the downloads section that might help.
What PLC's do u use? That will make replies to the trends easier.

If you know other bus systems it shouldn't be to hard learning and understanding DeviceNET, the diffucult part is knowing your PLC configuration software.

I have application knowledge of Devicenet and believe an easy system to use is AllenBradley. But you do need the software Rsnetworx.
The web site has some dood info

Omron Device Net configurator is far easier to use than AB. I use both and prefer Omron.

Device Net is very stable. Most problems arise from not abiding by the rules. Use the right cable, check with your supplier as to allowable lengths of cables, speed etc.

Abide by the rules and it works well.

I have not used AB for Device Net in standard off the shelf mode. I expect they would have a similar mode to Omron. Omron standard mode for digital I/O does not even need a configurator for a simple syste. Just plug in and the PLC scanner will pick up and automatically allocate digital I/O to default channels on the PLC.
