Windows restart
USB device is not detected after Windows restart due to blue screen
If the message "USB Device not recognized" appears after a Windows restart due to blue screen, disable the "Restart
automatically" option after a system error.
Restart Windows with the system function "SHUT_DOWN".
Windows restart during operation of the software controller
Depending on the state of the Windows system, proper restarting of Windows is not possible in rare cases. In very rare
cases, furthermore, the Windows restart can result in a defective state of the software controller. You should therefore avoid
Windows restarts of a machine or plant during productive operation.
If several PROFINET interfaces are assigned to the CPU, use separate subnets for each real-time end (I/O communication)
and Windows end.
If Windows fails to start correctly after a restart or an (HMI) communication to the controller is faulty, you can still operate the
software controller as long as you want until your application permits a short-term shutdown. Remedy the situation with
Power Off/On of the complete PC (Windows and software controller).
During a Windows restart, remove the CD/DVD from a permanently installed DVD drive.
Note
To ensure trouble-free restarting of Windows, observe the information about BIOS, image and driver versions in the
Reference data (Page 28) for the supported IPCs.
Windows restart with external graphics adapter
For the "Windows restart" functionality to be supported, configure the Intel graphics adapter as the primary graphics adapter.
Use of the Windows recover menu after a Windows crash
Selection in the Boot menu
To ensure real-time capability during the boot phase of the system, the USB ports are disabled during the Windows boot
process. In order to run the Windows recover menu properly, restart the complete PC including software controller and
select the "Windows only" option in the Boot menu.
Avoiding loss of data
To avoid loss of data, select the "Start Windows normally" option in the Restore menu.
Jitter during Windows restart on SIMATIC IPC with TPM
Jitter can occur on a SIMATIC IPC with TPM module during a Windows restart.
Checking return values in isochronous mode
If you use the software controller in isochronous mode, you may experience timeouts during a Windows restart. Check the
return values of the isochronous SFCs (126 and 127).
To keep the number of timeouts as low as possible, use a high send clock for isochronous mode.
Recognizing Windows restarts
During the start, termination or crashing of Windows a diagnostic buffer entry is generated and a diagnostic interrupt (OB 82)
is started.
Reset to factory settings
Use the TIA Portal to restore the factory settings of the CPU.
