Array transfer with variable lengths

Create functions (FUN) or function blocks (FB) according to IEC 61131-3 3rd Edition, to which you transfer arrays with variable lengths. Declare a VAR_IN_OUT with the star operator "*" in FUN/FB and read out the transferred array boundaries with the global functions "LOWER_BOUND" and "UPPER_BOUND". FUN/FB created in this way can be called and used with arrays of different lengths.

Larger Arrays (Clip)

The CODESYS Development System displays a maximum of 1000 fields of arrays in the online view in the declaration part. If you use larger arrays, you can freely select the area of the 1000 displayed fields by double-clicking on the array.
