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…
