2-1-3 Switch Settings
Node Address Switches
Set the DeviceNet node address using the rotary switches on the front of the
NE1A-series Controller.
Note 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.
IMPORTANT
• Turn OFF power to the NE1A-series Controller before setting the rotary
switches.
• Do not change the rotary switches while the power is ON. The 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.
Note
• Use a small flat-blade screwdriver to set the rotary switches, being careful
not to scratch them.
• Refer to 4-1 Initial Setting for software setting procedures.
Baud Rate Switch
The DeviceNet baud rate is set using the DIP switch on the front of the NE1A-
series Controller. The baud rate settings are shown in the following table:
Note The baud rate is set to 125 kbit/s at the factory.
