This tool downloads compressed control applications to local or remote Unitronics controllers. You generate a compressed application from within either U90 Ladder or VisiLogic. Your end user will be able to download the application, but will not be able to view or modify it. The tool can download applications and OS.
Sorry for lack of info at outset - New to this forum !
All sorted - appreciate help - HS inputs now properly defined, and Hardware setup now corrected
Quite a newby to Unitronics Vision, still getting my head around the basics !!
Thanks for your reply,
The card is formatted as Fat32
Card size is 32GB.
I have attached a screenshot of the SD cards properties, shown from unitronics.
There is a file within the folder Unistream_Files -> File_System.tar.gz which is 507.730kB so this 507730000 Bytes. This exceeds the size listed above.
But this file I think, is created by unilogic?
Some further information :
IF the SD Card has been formatted in FAT Format :
By design, FAT carries a few limitations:
Maximum file size is limited to 4,294,967,295 bytes.
Maximum files within folder is 65,536 (i.e. a directory must not be larger than 2,097,152 bytes).
A root directory on FAT12 and FAT16 can hold max 512 files/folders (there is no such limitation for FAT32)
That is a different issue, the details on the screen are different. In your case Fernanda, the PLC has lost it's Visilogic project. The most likely reason is that the on-board battery is flat (check the value of SB8) and the project was not originally downloaded with either the "download all and burn" or "Burn upload project" options.
