Before turning on the DeviceNet device, be sure to supply
network power. Some slave devices use the network power
as the operating power of the own node, and some devices
enter an error state when the network power is not
supplied. The network power has to supplied first.
Without network power, DN611B will not be able to communicate
with slave devices.
Ensure that there are no nodes that connected to the
network but not supplied with network power.
A node that is not receiving network power can cause malfunction
with other nodes' communication.
Turn off the nv type1 light controller at the last, so that the
master device (DN611B) will not disappear from the
network.
If not, it may cause malfunction on slave devices.
Do not shut down the network power while network
communication is running.
Refuse do so, the communication of entire network will stop and
whichever nodes will bused off.
