Errors When Downloading
Section 10-5
Connection failed.
Tried to configure a device on the DeviceNet network via the NE1A-series
Controller’s USB port, but connection failed. Check that power is turned ON to the
device and download again.
If the above cause does not apply, noise or other factors may be making
communications unstable. Check the following items.
• Do all nodes have the same baud rate?
• Is the cable length correct (trunk lines and branch lines)?
• Is the cable disconnected or slack?
• Is the terminating resistance only on both ends of the main line?
• Is there a lot of noise?
Program incomplete. Start Logic
Editor and check program.
There are open inputs or outputs in a function block used in the logic program.
Click the

Button on the Logic Tab Page to open the logic and perform the
following measures.
• Connect the open inputs or outputs.
• Change the number of I/O setting for the function block to delete the open
input or output.
