Hi Wizard,

I changed the local connection, but the com number does not change.

Hello,

It is NOT possible to back transfer project from OP77A and edit this project.

You can only make a Backup using Prosave, so you can Restore the project on the same type of panel.

You can NOT edit this backup.

When you want to make changes, you need the original project.

Best regards,

Wizard

really? I was known that if when we download program to hmi with option backtransfer function then after that we can use backtransfer again.

New question published by phuoc pha is split to a separate thread with the subject Can use back transfer function with model KTP600? .
