The card seems full with them, how did they get there? they're not part of my current project! The only possibility i can think of is that i have selected 'select all', for OB's in the step7 V5.2 blocks part of the project wizard one time. Thanks in advance. Ferdi.

The SFCs or SFBs you see in your block folder of your STEP 7 project are only providing the interface to program with (they have no size, as you can see in the block folder).
	Greetings, Chris
