I have connected 6ES7901-1BF00-0XA0 cable to com1 of my laptop and to IF2 connector on MP270B. Laptop serial is set to 8 data bit, 1 stop bit, no parity, baud 115200, no protocol. MP270B setup has Channel1 enabled and Remote Control enabled. WinCC flex transfer setting is set to Com1, baud 115200. But I am getting message FILE NOT FOUND when I try to activate Backup function from Transfer menu in WinCC flex andcommunication with the screen can not be established. What I am missing here? I have also PC-USB/PPI-RS485 cable 6ES7 901-3DB30-0XA0 for communication with S7-200(222). Can this cable be used to backup touch screen file? (PLC-MP270B communication cable has back socket with terminating resistor at the PLC side).

Since there is no check mark at "Enable back transfer" option in theTransfer Setting of the copy of the project I have I assume it was not transferred. So does it mean there is no way to retrieve the project the touch screen is actuallyrunning or compare it to the one I have on my laptop?And why Siemens' screens require two copies of the project: one to run it and second as a file for back transfer? Why isn't it the same as with PLC?

Nemo Posts: 3149 Rating: (172)	Hi, if you download your project to your panel WITHOUT the option backuptransfer your customer will not be able to change your engineering. He is just able to use the Runtime-version => your engineering know-how cannot be accessed/copied/modified [:D]... nemo

Nemo Posts: 3149 Rating: (172)	Hi, as I´ve tried to explain in my previous post..... If you are giving your customer just the Runtime-project your engineering knowhow is protected - that´s certainly the intention of most engineering companies. And if you are handing over the engineering project as well, your customer can do any changes/modifications. In software-developing business it´s quite common, that you don´t get the sources...or have you ever seen Microsoft handing over its sources for MS-Excel?[:D] nemo

And insituation when copyrights protection is not an issue it makes life much easier for theuser. No worries about making sure I have the right copy of the project to make changes. Just walk to the HMI/PLC and upload it. But hey, if you don't have what you like you must like what you have.
