OB1 Program Download Problem

Hello Dear Experts

I have a problem when I start writing a simple program in OB1 but the button for download is deactivated.

before writing the program I downloaded hardware configuration on PLCSim.

Thanks in advance

Best regards

I did but still doesn't work 

It seems you are checking it in simulation mode.

Before checking, have you download OB1 in CPU? 

Please check

The problem is that I can not download OB1 on the CPU.

When I double-click on OB1 in the Blocks folder in Simatic manager and open OB1 in "LAD, STL, FBD Program" the download button is not active.  I can not write a program in the LAD language and download it, but if I write a program in CFC, it works Perfectly and I can download it.

I really don't understand this.

 Hello,

Please go to properties of your Project.

Then you see tab 'general' -> uses  (this should be STEP 7) in stead of PCS7

 Hello,

I have no explanation for this.

But when you mentioned about CFC, I thought about this setting.
