Access to directories
The OPC UA NC Server enables read and write access to the TNC:
and PLC: drives.
During access, the permissions of the user to which
the certificate used is linked are active. The directories
and files displayed, as well as the access options, vary
depending on the permissions.
If user administration is active, the private data of others
users cannot be accessed.
Further information: "User administration", Page 427
The following actions are permitted:
Creation and deletion of folders
Reading, editing, copying, moving, creating, and deletion of files.
While the NC software is running, the files referenced in the following
machine parameters are locked against write access:
Tables referenced by the machine tool builder in the machine
parameter CfgTablePath (no. 102500)
Files referenced by the machine tool builder in the machine
parameter dataFiles (no. 106303, branch CfgConfigData no.

The OPC UA NC Server enables access to the control even if the
NC software is switched off. You can e.g. transfer automatically
created service files at any time as long as the operating system is
active.
Caution: potential damage to property!
The control does not automatically back up the files before editing
or deletion. Files that are missing cannot be restored. The removal
or editing of system-relevant files, such as the tool table, can
negatively affect the control functions.
System-relevant files must be edited only by authorized
specialists
