Hi people
I'm new to the forum and I'm in need of a little bit of advice if anyone can help, I've been tasked to make a small modification on one of our s7 300's, we currently do not have the programme for it so I have been able to create new project and upload the existing project to the new one. The question I have is that when I viewed the accessible nodes originally I noticed quite a few SFB and SFC blocks (which are protected) but when I view the blocks on the new project these haven't been uploaded, having managed to find what I'm looking for and make a small mod to one of the FC blocks when I download the programme to the PLC am I likely to download and basically screw up because there are no SFB and SFC blocks to download or are they a permanently in stored in PLC and it doesn't matter?
Thanks in advance
Jimmy
