call function block in a function

[Stuartjl 0]

Hi, i want to call a function block from within a function block. What I want to know is, what the syntax should look like and how you can use the output from the FB you are calling. Stu *in title it should be "call function block in a function block". Edited 30 Oct 2012 by Stuartjl

The syntax will be the same as calling the function blocke from a Program POU. I've just tested this: Create a FB in ladder. Crate a FB is FBD. Call the first FB from the second. Call the seconde FB from a Program POU. Outputs are used by right-click and "assign"... Compiles ok. Seems pretty straight forward so I'm guessing I've misunderstood the question?

Nice one, thank you very much. Sometimes the syntax can be very confusing
