SD Card Browser

Placing this variable on screen enables a user to press a button to display all of the files in the specified folder.

Touch Screen models: The user presses the Browse SD on-screen button. If file selection is enabled, the user touches files names to select them.
Non-Touch Screens (V130): The user presses the Enter button, and navigates between files using the arrow keys.

SD Ladder Functions enable you to read/write data between an SD Card and PLC memory operands, including blocks of file data, Data Tables, and Trend data.

You can also enable the user to delete files, or to copy the file name to an operand vector. You can control whether to display the Delete button by using the Hide Delete File MB.

Note ♦

The SD Card Browser only displays file types that are relevant for the requested folder. For example, when you view DT files, you will only be able to see .udt and .fdt files; if there are other files in the folder they will not be displayed.

In the Web folder, all file types are displayed

Note that in VisiLogic versions earlier than 8.0.46, EXCEL folders cannot display .txt

files. In addition, PLCs running an OS earlier than 3.0.59 do not support .txt display.
