I got an answer to my recent question, but i still dont get my vi work properly. In the front panel you can use "data opperations" to reinitialize to default value,do there exist an simillar function in the wiering diagram. I tried to init the shift reg. with a constant, this works, the only problem is that the init. occures for each time the shift reg "shifts" even if I wired the init. constant from outside the monetoring vi......
