Hello,
I have a FB that accepts an array of booleans, 16 entries. How can I programmatially check their value (e.g., if MY_Array()[7] == false)?
I tried with the following snippet but it doesn't work. Also, there is no similar example in the current repo, it seems.
if(RESET_Array()[i] == false) {
x = i;
break;
}
Thank you for your support!
Agostino

Hi,
The syntax for accessing variables and arrays from C++ is not that clear. We had to do here some tricks to make our ST code generation easier. Therefore I can recommend to test such cases in ST generate the C+++ code and look there for reference. Or even better, if possible write your FB's algorithms in ST.
For your example the code would be:
if(RESET()[i] == false) {
x = i;
break;
}
Cheers,
Alois
