Disappering SFC blocks

Robobob Posts: 5 Rating: (0)	I am using Step 7 ver 5.4.4 Today while doing some programming all of the SFB blocks disappered from the program elements window. I was going through it trying to find SFB-35 and there were many SFB displayed there.Then all of them were gone. When I click on the SFB icon in the elements window nothing is displayed. If you look at my screen shot you will see that there is no + sign beside the SFB blocks. Any ideas on how to correct this or how it happened. Did I fat finger somthing? Help I need to use them... I posted this in the wrong forum group this morning sorry for the cross post. thanks Bob Attachment STEP 7.JPG (153 Downloads)

In the Open Project window, you have four tabs User Projects, Libraries, Sample Projects, Multiprojects Click on Libraries 4. Select Standard Library 5. You will see a list of S7 Programs Click on System Function Blocks 6. You can find your SFB35 there. Regards, Behnam www.sigmaprocess.ca
