Service Commands

3.1

Using service commands

Overview
The service command 'sc' is a tool used for performing a range of service tasks on a
SINUMERIK NCU. The required action is written in the command line after the 'sc', e.g.: sc
help
This action produces a list of all actions with a short description. After the action, further
parameters or options can follow.
'sc' is available in both the NCU basic system and the service system (mostly in the form of a
USB memory.) However, some actions are only useful in one of the two systems
(NCU/Service). This is noted for each action.

The most important terms and abbreviations are explained in the glossary.
Privilege levels
The 'sc' command can execute its actions using more privileges than are normally granted to
the calling user. For example, starting or stopping subsystems requires root privileges, but
'sc' allows every user who belongs to the 'service' group to do this.
Each action of 'sc' is assigned a "privilege level". This is a user group to which the user must
belong in order to execute the action. As the groups are hierarchically nested, members of
"higher" groups can also use the action in question. For example, the group 'manufact' is
above 'service', which means that members of the group 'manufact' can call all actions that
require the privilege level 'service'.
The privilege level that the caller requires is noted for each individual action. The possible
levels are (in ascending order):
● none
● operator
● user
● service
● manufact
