JensS Posts: 739 Rating: (55)	you are using a wrong operator panel (BOP) If you plug a BOP to a MICROMASTER MM430, or a BOP2 to a MICROMASTER MM440 or MM420, then "- - - - -" is displayed. BOP Basic Operator Panel [6SE6400-0BP00-0AA0] for MM420 and MM440 BOP-2 optimized Operator Panel [6SE6400-0BE00-0AA0] for MM430 See FAQ: http://support.automation.siemens.com/WW/view/en/23623849
