i think i made a great misstake.
i use an arduino uno without atmel as ISP. now i connected the +5 V and the GND from arduino to the breadboar where also is a GND for 24V.... +5V (from arduino) and +24V never has contact.... but the two GND.
the the arduino want work as an ISP and also writing to his own Atmel did work.
Time for a new board ???
