Hello Friends,
I am new to Siemens programming and I am learning a bit of programming using LAD logic.
What I do now is use only the OB1 and do all my little programs there only and check by using the simulation feature. I am using Siemens S/w version 5.2 and mostly the CPU is S7 300: 315 2DP.
I desperately want to know how I can use the FC,SFC,SFB,DB for creating my programs with better flexibility.As of now I am using only the OB1 to write all my program in it.Can I use other Ob's also ?
How do I call the different Functions form my main program and how do they return the values ?
Any help with a small example would be most appreciated.
Is there any way I can get some real programming examples , easy enough for a beginner like me ?
Thanking you all in advance
