3 File Copy Function
29-38 WindO/I-NV4 User’s Manual
3.5 Precautions
• When the MICRO/I is under the Run Mode, the maximum size per single file that can be read or written with the
File Copy function is 256 MB.
• Access to the file being copied is not allowed while the file copy function is running. Therefore, data may be
missing when copying files used by the running project such as log data. When copying a file used by the running
project, use File Manager on the MICRO/I under the System Mode.
• While running the file copy function using a Key Button, Multi-Button, or Multi-Command, if a data transfer function
(project transfer, PLC program transfer, or file copy) is initiated, the only function that will work is the currently
running function. If two or more data transfer functions are configured to a Multi-Button or Multi-Command, only
the data transfer function displayed at the top of the function list on the parts property dialog box is run.
