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.
