Copying string from array of structures

[pabspagg]

Hello!

I am trying to copy a part of a structure to an array. This is how my structure looks like:

The variable that contains the structure:

I want to move only the first variable ("nome") to an array of strings. I tried move, arymove, memcopy, left,mid ,right, everything I could think of. But nothing worked.

I think the problem is the string was typed in the nb designer IHM and saved on the plc. But what NB designer does when u type a string? Is it converted?

I did a test and this is how it looks:

 

The first part (Receitas[1].nome)  was typed  on the NB designer and the instruction move doesn´t work.

The second one I forced the value on plc and it worked. What am I missing here?

Thank you!

I can't see where you are using the variable ARRAY_RECEITAS ? is that ladder screenshot in a function block?

It looks like you may have declared 2 variable arrays 1 called RECEITAS and another called ARRAY_RECEITAS

Sorry. I have a function block which takes Receitas -> ARRAY_RECEITAS(Input from the fuction block). I should have printed outside the function block!

I think the problem it's about typing the string in the NB designer.  When I do and goes to plc (Receitas[X].nome), maybe it's not a string at all? Maybe array of words? Not sure though. 

If I force a string in the structure, I can copy easily. But if I get the string from the NB Designer I wasn't able copy it.

If I'm not clear , just tell me. I will try to explain a better way.

Well, I have just found out a document which explains what's happening.  

I will test tomorrow if It works!
