Hello everyone

ADD 1 Free function block cannot read the value of r2050[1] pzd word 2 from r20099.

In the ADD 1 function in the picture, pzd word 2 connected to the x0 input does not add the r2050[1] value with other inputs. It returns the result of other values connected at the x1 and x2 inputs of the ADD 1 block, but does not add the result of the r2050[1] value. I can read the results in x1 and x2 entries in r20099, but why doesn't it add r2050[1] in x0 entry to them.

Does anyone have an idea about this.
