Data Transfer Function
1.6 Precautions
• An error message is displayed if the project upload or download fails.
For details, refer to Chapter 36 “1.1 Errors Displayed on the Screen” on page 36-1.
• While the project transfer function is running, the MICRO/I stops processing other functions.
• When project data is downloaded using the project transfer function, the HMI Keep Registers and the HMI Keep
Relays are cleared.
• If a file exists with the same name in the save destination when uploading a project, the file is overwritten with the
uploaded file without displaying an overwrite confirmation message.
• When using the project transfer function, make the project name alphanumeric characters. Note, the file name
must not contain the following characters:
\ / : * ? " < > |
• While running the project transfer 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
will run.
• When running the project transfer function, the external memory device must have enough free space equivalent
to the size of the ZNV Project File(.znv). Check that there is sufficient free space on the external memory device
that will be used with the project transfer function. If the device does not have sufficient free space, the project
upload or download may fail.
