SCADAPack X70 logic Functions Blocks in ST

[AlbertoArdila]

Hi

I created a function block and I want to use it in a program / section in structured text (ST)

The code of my function in the section is:

FB_Division_0 (Numerateur := A,

               Denominateur := B,

               Division => C);

I am looking for best and simple way to write this function in my section, like:

C := FB_Division_0(A,B)  

But it gives me the Error E1064 call of non-function.

Can someone tell me please what I am doing wrong?

Thank you.

The error message has it spot on:

---

Error E1064 call of non-function.

You are trying to call something that is not a function, as though it were a function.

You have created a Derived Function Block.  The Function Block may only have a single 'Output', but this doesn't matter, the format of a Function Block is such that it shouldn't be expected to 'return' a value that can be assigned like this.

So the way that you should probably be calling this is:

FB_Division_0(A,B);

C := FB_Division_0.Division;

I actually may even be wrong on the parameter passing, it's possible that you have to set the inputs individually, i.e.

FB_Division_0.Numerateur := A;

FB_Division_0.Denominateur := B;

FB_Division_0();

C := FB_Division_0.Division;

Hi BevanWeiss

Yous solution works well

.

FB_Division_0(A,B);

C := FB_Division_0.Division;

Thanks for the answer.
