Example

void Iso11783PDDOnDataChanged( dword ecuHandle, dword ddi, dword elNum, double value ){
  switch( ddi) {
    case 0x200:
      switch(elNum) {
        case 2:
          // set values of sections
          Iso11783PDDSetValue( Sprayer, 0x200. 3, value );
          Iso11783PDDSetValue( Sprayer, 0x200. 4, value );
          Iso11783PDDSetValue( Sprayer, 0x200. 5, value );
          gOutputPerArea[0] = value;
