Function rights for server and client
The corresponding function rights for the client or the server must also be enabled for users
of the client function and users of the server function on an S7-1500 CPU. It is not enough
simply to save the user name and password centrally.
Here is an example to illustrate this type of rights use.
1.
Under "Security settings > Users and roles", you define a new role in the "Roles" tab with the
name "PLC-opcua-role-all-inclusive", for example.
Tip
: The tab may be covered by an information window ("The current status has not yet
been checked..."). In this case, first close the information window.
2.
In the "Function rights categories" section, you navigate to the runtime rights and then to
the CPU function rights, and select the CPU whose function rights you want to set.
