S7-1200 locked out by password

[mcmoney]

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!

You have to contact the original manufacturer and ask them for the program and password.

That said, IMO if this is a standard product from the vendor, then it should be so well-documented, debugged and with so much integral diagnostics that it should not be necessary for an end-customer to look into the code for troubleshooting.

If these machines are still under warranty the manufacturer may not want you connecting to the machine for any reason.

If this is a standard product and not a custom, I'd bet the manufacturer doesn't want anyone but their people making a change for liability reason.
