Step 7 V5.6 Sp2 project compatibility with Lower versions

Hello s_vb;

Up to v5.5, Simatic Manager was backwards compatible, which means that you could use a later version (v5.5, for example) to upload a v5.4 program on a CPU. The contrary (reading a V5.5 program with v5.4) was not possible.

I have little experience with v5.6 and its different upgrades, so I cannot be totally sure that you can do what you want, opening a v5.6 SP2 program with a v5.6 HF5. If development of Simatic Manager followed the same structure as before, you probably can not. A service pack is generally a big step in software development, and often implicates changes in the databases they use from an earlier version, which can cause problems on opening a project.

Basically, we can give you no guaranties.

Why don't you simply open your project with the version you have and you tell us how it went? Do not be satisfied with simply seeing the hardware configuration or a few lines of programming, try to go online and do a few VAT tests, maybe a new upload. This is the only way you will be sure that what you want to do is possible.

Hope this helps,
