Hello everyone.
I used to read/write code in Ladders. While this time, when I read a program with Function Block Diagram, I had a puzzle about how the code execute in FBD.
Let's say there are 3 sheets in the FBD. Sheet 1,2,3. And in Sheet 2, there are two operations: move A to B at area C1; move C to D at area B2.
So when running, in which order will the three sheets execute? First sheet1, then sheet2 then sheet3. Or else?
And in sheet2, in which order will the two operations execute?
Thanks in advance!
