Thanks for everybody, problem got fixed now. But after all outputs was released and machine start working, some of outputs and function still not working. Looks like some parameters is missing, after I restored program from the EEPROM card. Machine has an HMI, but nobody knows what to change.One of the most critical - the Stop Bottom not working any more, in the stand by position, the input from the Stop Bottom(INC) is present in input module, but after machine start moving by the regular Start bottom - the input from the Stop bottom disappear from the Input module and only one way to stop machine, is E-Stop. Any suggestions,please? P.S.How can I place the sample PLC code, that I pulled out from the EEPROM card, here?
