64
Set the DeviceNet node address using the rotary switches on the front of the
NE1A-series Controller.
Method Two-digit decimal
number
Range 0 to 63
The node address is set to 63 at the factory.
Any node address in the setting range can be used as long as the same
address is not used by another node. If a value between 64 and 99 is set on
the rotary switches, the node address can be set using a software setting on
the Network Configurator.
Use the following procedure to set the node address using the Network Con-
figurator.
1. Turn OFF the power and then set the rotary switches to a number between
64 and 99 (software setting).
2. Turn ON the power. The NE1A-series Controller will operate using the pre-
vious node address (factory set to 63).
3. Reset to the default settings using the Network Configurator's RESET
command.
The configuration information held in the device will be initialized.
4. Set the node address from the Network Configurator.
From here on, the NE1A-series Controller will operate with the node address
set in the software setting.
• Turn OFF power to the NE1A-series Controller before setting the node
addresses.
• Do not change the rotary switches while the power is ON. The NE1A-
series Controller will detect this as a change in the configuration and will
switch to Abort State.
• A node address duplication error will occur if the same address is set for
more than one node. Communications will not start if this error occurs.
Use a small flat-blade screwdriver to set the rotary switches, being careful not
to scratch them.
