Siemens SINUMERIK 840DE sl Commissioning Manual page 1365

As explained above, an SMB file system is connected as the specified user. To prevent a third
user from executing file operations on the control in the name of the connected user, the local
directory can normally only be accessed by the latter (and all members of the same group).
However, if you do want to make the remote directory available to further local users, you can
use the "-public" option to make the MOUNTPOINT belong to the "operator" group, and this
access is therefore guaranteed.
2.5.6 Disable
Description
Syntax:
Alternative names:
Authorization level:
The "sc disable" command switches the specified subsystems off. These subsystems are then
not loaded again at the next cold restart. You can also switch several subsystems off with a
single "disable" command. "hmi", "nck" or any other subsystem names can be used for the
subsystems.
Note
The "sc disable" command acts on the parameters in the basesys.ini file located in the card/
user/system/etc/basesys.ini directory.
"sc disable IPAlias" deactivates the second alias IP address for the X120 network interface.
See also
"InternalIP_Alias" and "InternalNetMask_Alias" parameters in the "basesys.ini" file.
Special subsystems
The "DHCPSvr" name is a special case. This does not switch a normal subsystem on or off,
but specifies whether or not a DHCP server should be started on a network interface. The
interface is entered in the standard form.
The synchronization of the DHCP server is switched on and off with "DHCPSync". The
synchronization is only possible in the system network.
The "sc enable" and "sc disable" commands function by changing certain variables in the /user/
system/etc/basesys.ini file. The associated variable is "DisableSubsystems" or
"DisableDHCPD<INTERFACE>" for subsystems and DHCPSvr, respectively.
