NOTE:

1)Each DN-3000 can support up to 32 PLCs/Devices (if they are network addressable internally).

2)The DeviceNet Host can address a maximum of 63 DN-3000 units.

3)Multiple Brands of PLCs or Devices may be addressed by the DeviceNet Host by using multiple DN-3000s, but only one PLC/Device Protocol may be used on a single DN-3000 unit.

4)If multiple DN-3000s are to be used, each DN-3000 must be configured with a unique node address (MAC ID) on the DeviceNet network.
