Note 1. All three power supplies can be turned ON simultaneously. It is also ac-
ceptable to turn ON the communications and Slave power supplies or the
Slave and PLC power supplies simultaneously.
2. Slaves may not be recognized if the communications power supply is
turned ON after the Slave power supply.

When the scan list is enabled, the user can check whether Slaves are par-
ticipating in the network from the PLC and verify that the DeviceNet net-
work is communicating normally.
