Hello I am relatively new to PLC programming and even newer to siemens. Our company purchased 4 concrete batch plants which came complete with S7-1200 hardware and a PC used for HMI. I have had not been able to access the program on the PC which is locked by an O-key USB dongle and the manufacturer is no help. I have V11 TIA portal on my lap top and when I try and download the program connected direct to the PLC I am again locked out by password.
I really need to at least view the program for troubleshooting purposes and even better would be the ability to edit.
Does anybody know a simple method around this. Please help!
