Connection between Factory I/O and S7 1215

Hello,

I made a project and Just wondering why not everything is working. I do have conveyor in Factory I/O and plug in to real s7 1215 Dc/Dc/Dc. In factory I/O my start button or stop button is working and real start and stop button is working too. But I do have switch (2position) and in Factory I/O dosent work same like sensors. I want to have some of sensors in factory I/O some of them in real plc but I think this can not work. When I plug in factory I/o to 1215 without real buttons etc. dosen’t work too (buttons etc.) Where can be problem?

Switch is on “TRYB Manual” but in Tia Portal is still NO… but sometimes have like 1s signal on…
