4.1 User administration

4.1 User administration
User administration
To establish a connection to the OPC UA Data Access interface, an authentication with user
name and password is required.
Note
Anonymous connection
You can also establish an anonymous connection, but none of the functions will be available
(feedback: "BadInternalError").
For an initial connection, you must use the administrator user and password assigned when
OPC UA was set up. Methods with the following functions will then be available under the node
"Sinumerik/Methods":
● Add own users
● Delete own users
● Assign rights
● Remove rights
Note
You can only add/remove users/rights if you are connected as administrator. If you call the
methods with a different user, you will receive the message "BadInvalidArgument".
After OPC UA was set up, the administrator user has read access to all data ("SinuReadAll")
but no write access. Use the methods "GiveUserAccess" and/or "DeleteUserAccess" to
adapt the access rights as required.
