Fatal Error when going online from ControlBuilder Professional
800xA 5.1 FP3.
Something happened with ControlBuilder project. Message is appeared
"Fatal Call to ErrorHandler, see log file" and we can't go online. Log files and
screenshots of error messages are attached.
What could be a reason for this error? Could it be resolved? Or I have to go with system's full backup?

126.96.36.199 is a hardware channel somewhere. You should be able to find it in the hardware tree. The channel number is quite high (66) so I guess this is some user defined profibus device, not an IO module.
The compiler is trying to resolve the variable connection from that channel to something in your application and crashing at that point. I guess the problem is it cannot identify the correct application - hence "unknown" and this is why it crashes.
If you check your SessionLog you can also see there is a warning in compiling your Siemens _DP_DP_Coupler hardware definition ...

Maybe this is related ?

Try looking for something around here. Its likely that this is the last change that you made to the PLC program. Try backing it out and see if that fixes it.
