DeviceNet Configurator.
Node address setting No setting required. Set using the rotary switches or
the DeviceNet Configurator.
Baud rate setting No setting required. Automatically detected: Uses the
baud rate set for the Master Unit.
Communications error output Set using the Setting Tool. Set using the DeviceNet Config-
urator.
