When the NE1A-SCPU01 is used in Standalone Mode, DeviceNet communications can be disabled. If De-

DeviceNet communications functions can be used.

Description
The unit starts in IDLE Mode after the power supply is turned ON.
To change to RUN Mode, the operating mode must be changed from the Network
Configurator.
Use this mode until device parameters have been verified.
If this mode is selected and the following conditions exist, the Controller will start in
RUN Mode after the power supply is turned ON:
• The configuration has been locked.
• The operating mode before the power was turned OFF was RUN Mode.
Even when Automatic Execution Mode is selected and the configuration has been locked,
the next startup will not be performed in RUN Mode if the power is turned OFF in IDLE
Mode. Turn OFF the power in RUN Mode to use automatic execution.
When disabling DeviceNet communications, connect the Network Configurator via the
NE1A-SCPU01USB port. If the parameters that disabled DeviceNet communications are
downloaded while connected via a DeviceNet Interface Card, an error will occur in the Net-
work Configurator because the DeviceNet communications of the NE1A-SCPU01 will
stopped.
