Lisa,

I recently discussed this concept with Norm Provost ( he was instrumental in 
the preparation of 1326 ), and I'm not sure that we agree.... but he is the 
Guru.

We have taken the definition of network to mean devices sharing the same 
source of power. For example, on a large machine, a single large dc power 
supply may deliver power to a controller, PLC, relays, valves, motor drives 
etc. We treat this as a dc network, because we think this is the responsible 
thing to do. We know others do not share this point of view.....

To discuss this further, contact Norm directly.

Best regards,

Derek Walton
