Upload and Download Logic
Upload Logic
To upload logic, select Communications > Upload. The logic
configuration in the device is read and displayed in the old Ladder
Editor. Any unsaved changes will be discarded and Online Animation
begins.
Note that because a device has limited memory to store logic, the
layout of the configuration is not downloaded to the device.
Therefore, the information that is uploaded from the device will not
match in appearance the information you downloaded to the device
(that is, the user interface will look different although the logic is the
same). If you want a record of the layout of your configuration, we
suggest that you print a copy of your logic configuration before you
download it to the device.
Also note that uploaded information is not automatically stored in the
RSNetWorx for DeviceNet softtware .dnt file. In order for updated
information and any other changes you make in the logic
configuration to be retained, you must use the Save function in
RSNetWorx for DeviceNet software after you exit the old Ladder
Editor.
Download Logic
To download logic, select Communications > Download. The logic
configuration in the old Ladder Editor is duplicated and transferred to
the device. Before a download can be performed, the logic must pass
the verification process. See Verify Logic for more information.
