Hello friends

Please I need your help , I've a new machine with S7-224 CPU, When I tried to backup the program from the CPU ( Uploading program ) , after typing the write password and communication is OK ,I get the message "The project file contains one or more old constructs that version 4.x does not support"

I tried to use all available previous versions of Microwin that we have starting from version 2 up to version 4 sp6 but I get the same message for the working versions which support CPU224

What could be the reasone and how can we solve this problem , by the way the system data and the data blocks are uploaded if selected alone without program block

many thanks for your great cooperation

I want to add some information that the machine is chinese , and the comments are in chinese , are there any relation about this in the mnetioned problem ?

Hello again,

So, I don't know if this new error regards CN version of CPU. But for sure you'll problem if you try to upload CN version with EU version of Microwin. Please, look at following thread - Chinese S7 200 CPU Support . There also you'll find link to another thread with more details about necessaries settings in Microwin EU version to be possible to upload CN version of CPU.

Hope this will helps.

Best regards,
