good day everyone.
right now i troubleshoot a STACKER MACHINE. the fault in the PLC CPU315-2 pn/dp is BF1 and SM fault. I check all the profibus cable and i found no problem. So i make it online in step 7. I uploaded the program and check the hardware configuration, then online. I scratched my head because in the actual field there are 2 Interface modules and 6 phoenix profibus modules and 15 micromasters 440 inverters link to profibus. The uploaded hardware configurations in the profibus show only 1 interface module and the 6 phoenix profibus modules, and all the micromaster 440 are all missing. I wonder what happen, why the plc hardware configuration in the plc program did match the actual field, in fact the machine was running normal on the other day. Is there is any possibility that the plc program was corrupted? need your help on this. thank you in advance.
