hi mr hosseini
s7 v5.5 and os: windows7
i selected true block and folder for download
this problem exist in office pc , i send pic for you

thanks

Why is the Download button grayed out in the selected block folder?
This is probably due to the fact that the project is set as a PCS 7 project. Depending on whether a project is used for STEP 7 or for PCS 7, the SIMATIC Manager adapts PCS 7-related functions and menu commands. Only the entire S7 station can be loaded into STEP 7 when the project is configured as a PCS 7 project. In this setting, individual blocks cannot be loaded without the CPU going into Stop mode. The Download button or "PLC > Load" function cannot be activated (grayed out) in the block folder which is selected.

Remedy

1. Right-click on the project or project name.
2. Then select "Object properties..." in the pop-up menu that opens.
3. Go to the "General" tab in the "Properties - Project" dialog and define the setting for use. Change the use of PCS 7 to STEP 7 here.
4. After clicking OK to save, the Download button or "PLC > Load" function can be activated, and you can load individual blocks into the CPU.

Download icon in Simatic manager will be available if you click the block or open the block. but if it still gray, I Assume that you are opening project with PCS7 option selected. One thing you only need to do is you have yo switch option PCS7 to step7, You can follow this step.
