Is there a version of Siemens software that can be used to view only the installed program logic and diagnostic buffer to determine system and bus faults. I don't necessarily want to be able to write or change a program - only view. Our machine manufacturer from Italy connected to our machine and told us that there were no faults in the PLC but the System Fault (SF) LED is on steady and the Bus Fault (BF) LED flashes on/off. So, I just want to view the PLC error log to see what is causing these LEDs to show faults.
