Description

Is your feature request related to a problem? Please describe. When trying to compile code with a comparison statement which tries to compare incompatible types, we currently do not validate against it and the compilation will fail during codegen.

FUNCTION main : DINT
        VAR
            x1 : ARRAY[0..2] OF TOD;
            x2 : STRING;
        END_VAR
            x1 > x2;  
            GT(x1, x2);
END_FUNCTION

Describe the solution you'd like We should validate if the two types in the binary expression can be compared to each other
