Sum of 4 values in the HMI with a macro


A simple example of macro in the HMI for to do a sum of values.

If I want to do somthing like this : LW4 = LW0 + LW1 + LW2 + LW3

Note: LW is the HMI words register.

#include "MacroInit.h"
void Macro_main(IN *p)
SumLw = LW0+LW1+LW2+LW3;

You can download this HMI project example: Macro sum of LW values
