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, DN912 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.
Power on all slave device before starting communication
with DN912.
If you start DN912 communication while the power of the slave
device is not turned on, the DN912 will display a non-response
error for the slave device that has not started.
Turn off the nv controller at the last, so that the master
device (DN912) will not disappear from the network.
If not, it may cause malfunction on slave devices.
