Applicable to S7 F/FH System: What do you mean by a "custom F-Block"?Do yo mean Block types in CFC?Normally you can use " F_BO_FBO (conversion from Bool to F_Bool) " to incoperate standard boolean variables into a F-Block in case of F-Bool data type.

Hi,hdhosseini Thanks for reply. I have a custom F-Block compile from CFC( using Compile as FB). I think i can use some input/output as standard data type with s7_m_c properties and than can create these variables in OS(In Manual it say can do this). But as you said, I use a convert block convert Non-F Data to F-Data then use these F-Data in my logic. But when i compile this CFC as FB, I got error, say standard block and f-block can't togrther, I'm not really know what that means. espacial in F-Type to Standard type(link F_FB_B), I know F_FB_B is a standard block, when i put it in my CFC, it should be in other OB( my F logic in OB35). How can I do?thanks. |

For F Block type, develop it in an S7-Program outside the current project.First try to use all F data types inside the block type.When you finished your task, copy the FB and other created blocks in to your main "Blocks" folder, import and assign standard BOOL with conversion to F BOOL from outside!
