Creating Project files (.dvi, .vdf, .urc, .ura)
Project files contain application data in compressed format. There are several
kinds of files.
Clone Files:
These can contain complete applications in compressed format, including
Ladder and HMI applications and OS. Clone files are very convenient for
OEMs, or for those wanting to 'Clone' a PLC and its application. These files
can be created in VisiLogic as well as via SD Clone Ladder functions or in
Information mode.
Project Files: UniDownloader Designer
These files include both the Ladder and HMI applications, Data Tables, and
an Upload file.
-Standard Vision: .dvi files
-Enhanced Vision: .vdf
Note that the DownLoader files you create here are compatible with
UniDownloader 4.0.0 and later; provide your users with the correct
UniDownloader version.
Cache files: Remote Access and Remote Operator
These are compressed HMI Displays. They improve Remote Access
reaction times, and must be used to display graphic images when using
Remote Operator.
- Monochrome Vision (.ura files)
A .ura cache file enables Remote Operator to load Displays more quickly.
Note that V130, which loads displays quickly, does not use .ura files.)
- Color Vision (.urc files).
If a .urc is not used, images are not displayed and fonts may be
distorted.
A cache file includes fonts, and can include images.
If the file does not include images, a red 'X' displays in place of
graphics.
To create Project files:
1. Click on the Project menu and select Create Project files.
