Getting Started Downloading/Uploading a Project
VisiLogic: Getting Started 25

To upload a project from a controller:
1. Connect the controller to the PC.
2. Select Upload icon from the Connection menu; the Vision Communication
PC Settings window opens.
3. Select the connection type and click Exit; the uploading process begins.
Upload copies the complete project from the controller into the PC.
Via Project Properties, you can apply upload and download options:
Assign a project password. Password protection requires users to enter a
password before uploading a project to a PC.
Prevent project upload.
Note
•
Security restriction: if a PLC operator enters a wrong password
9
times, the PLC automatically disables program upload for that
program.
Resetting the PLC will enable you to try another 9 times.
The limit set on password entry is intended to provide an additional
layer of security. For example, this can prevent a hacking script from
entering a networked PLC, since the number of attempts is limited
and such a script would not reset the PLC.
Why can't I upload a project from the PLC?
Project upload may have been disabled. In this case, the controller
displays the following message at upload: "This project cannot be
uploaded because:
- the option 'Burn Upload Project' was not selected when the project was
downloaded,
or
- due to incomplete data in the PLC", and upload fails.
You are not entering the correct Upload password set in the Project
Properties of this project.
Are USB port adapters available?
If your PC contains only USB ports, and your OPLC does not offer a USB port,
you can connect a Unitronics OPLC via a compatible, external USB-to-serial
converter.
Unitronics offers a USB-to-serial converter that has been tested for compatibility
with OPLC controllers. This converter can be ordered from local Unitronics
distributor, using part number MJ10-22-CS35.
