Could you please give us some detail on what type of "reset" you did (e.g. power off/on OR Stop/Start of individual CPU etc.) and what you mean by "the3 cpu go alsointo default". Apart from that, there are two manuals that you should consult and which have the required info on how to do a coordianted/synchronised Multi CPU startup in an S5 which in your case are: S5-135U Programmable Controller CPU 921, CPU 922 SIMATIC S5-135U/155U System Manual I hope this helps
