Hi Be True, I think that I know wat is happening. [:o] First of all I have give in the AND-port and after that the OR-port, you may notice that in the AND-port 1/1 is there and that in the OR-port 1/2 is there. Now there is now problem. But when the two ports are switched so that the OR-port is first and the AND-port is second, when the OR-port have now a “ You can see in which order the different blocks are worked thru when you look in the Runtime editor. Here you can see that the AND is done before the OR. When I change the sequence then it looks like the way it is under here. Now the OR is 1st and the AND is 2nd. So the blocks have to be composed in the right order, “Optimize RUN Sequence” from the “Options” menu would not help you here! See the pdf for the pictures that are described before...

I hope that the answer will help, if you have still questions, don't hesitate to ask me. |

[quote user="be.true"]Unfortunately, Imet withanother problem similar to the AND and OR sequence problem. This time, it is an RS_FF and OR sequence problem. I believe I need to know more about CPU's internallogicsolving mechanism or principles. Could you tell me where to find such instructions or reading materials? Hi Be true, Our friend from Brasil have give you some FBD handbooks, there is also a handbook for CFC: CFC for S7 V6.1please consider that the SCL source is not the end of the compiler, that code is translated to STL.
