• General (includes Project Password)

  

   

  Note ♦

  Password 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.

  ♦

  Selecting Images: use the VisiLogic Navigation Panel When you place images in your application, the default navigation dialog box is proprietary to VisiLogic. To use a standard Windows dialog box, deselect this option.

   

• Download

  

  Parameters	Function
  Disable Project upload	If you select this, no user will be able to upload the project from the PLC, even with a password.
  Rebuild, then Download	Select this if the project was originally created in another VisiLogic version.
  Warn about Vision 120 Snap-in conflicts	This option is checked by default, causing, VisiLogic to issue a compilation warning message if the Vision120 selected in Hardware Configuration is different from the one to which you are downloading. Uncheck this option to disable such warnings.
  Compiled Ladder Allocation	If your application requires, you can select this option and enter a different amount.
  Back up and Restore PLC RAM Data	Backup a project together with all of the current values in Data Tables and all memory operand values. If this option is selected: At project upload, the PC will upload all of the current values in Data Tables and all operands--except for system operands. To back up system operand values, store them to memory operands. At project download, the PC will download the complete project, including all of the current values in Data Tables and all memory operands. Note that this option is not part of the project. It affects all the projects downloaded from the PC.
  Save Unit ID in Project	When you select the Save Unit ID option, the ID number of the controller selected in Connection>Communication & OS>Vision-PC Communication Settings is saved together with the project. You will not be able to download the project to another controller until the number is changed.
  Display OnLine Tools	Keeps the Test Tool bar from being displayed during Test Mode   .
  Check Digital Signature	Select this to check the digital signature of the project in a PLC every time PC-PLC connection is established.
