● Example for company network (X1):
sc_vncpwd set companynetwork mypasswd
● Command for system network (X2):
sc_vncpwd set systemnetwork mypasswd
The password must not be more than 8 characters long. Passwords are saved in encrypted
form in the following file: C:\ProgramData\Siemens\MotionControl\user\System\etc
\sinumerikvnc.ini
Note
Specification of the password is also required for remote access to an NCU (without PCU/IPC)
in the company network
As from SINUMERIK Operate V4.8 SP2 a password is required for access via VNC to an NCU
in the company network. The password is not yet defined in the factory settings. If the NCU is
to be accessed in the company network, you must specify a password as follows:
1. Call the command line of the NCU (TCU menu "Select service session > Show command
shell of NCU") or putty.
2. Log in as user "manufact".
3. Execute the "sc vncpwd set companynetwork mypasswd" command, whereby "mypasswd"
is a password with a maximum of eight characters.
Further information is displayed for the input of "sc vncpwd".
Further information
● Further information on the permissible network structures and network configurations can
be found in the Operator Components and Networking Manual.
