BSEND/BRCV, creating instance DB definition

I have been trying to write an FB for 315F-2PN/DP(ethernet CPU) from scratch. I have not found how to use LAD/STL/FBD-editor to insert BSEND and BRCV to the Static Data -area like in this example:

https://support.automation.siemens....extranet=standard&viewreg=WW&load=treecontent

The only way to use these functions has been to copy DB105 and FB105 from the example and modify those. What I am missing here?

Hello Juo;
You could try to follow the tips in the following FAQ:
How do you create and update multiple instances?</B />

Hope this helps,

Thank You Very Much!
It was that I had to create multi-instance FB of the caller of FB12/13. Now selecting data type as FB<xx> works fine. I couldn't even see my problem on that level yesterday of my frustration...
