It is working again but I don't know really why.
I changed to connection from the rp usb to serial arduino (pin 0 and 1) and there was no change.
Then I started up the serial monitor on the computer (which I used as power supply) and suddenly it is working ??.
If somebody can explain this, it would help to trust this system. Maybe the voltage off the rp not high enough.
how do you drive the relays of the neco ? direct ?
Could it be that you consume more than the few
milli Amps the arduino gives at the pins ?

Hello Andreas,
Thanks for the reply.
The relays are not attached yet (LED's instead of relays to check if it is working). I think the voltage on the USB connection on the RP is/was to low and not high enough for the Arduino to make the logic difference. Now it is working.
