hi, 3M system is very old more than 20years. i think the best way is to ask the former machine owner to get maintenece manuals you can also check the link below to download document for help but it is not easy for beginners i think your M/C may lost paramerters orPLC power broken or somePLC I/O broken or limit switches problems https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&aktprim=0&siteid=cseus&lang=en&siteid=cseus&extranet=standard&viewreg=WW&nodeid0=10805541
