Hello. I have looked searched in the forum but gotten no conclusion. My question is whether it is possible to go online/login to monitor the code and check diagnostics, even though the software i have is not the same version as online. Without having to download the software or stop the plc.

Second question: How is the possibility to open project from live PLC? Is it machine code or possible to read? I know how to do it, but not what i will receive. It is an old machine that is acting up and needs to be diagnosed.
