6 User Management
SILworX can set up and maintain an own user management scheme for each project and
controller.
6.1 User Management for SILworX Projects
A PADT user management scheme for administering the access to the project can be
added to every SILworX project.
If no PADT user management scheme exists, any user can open and modify the project. If
a user management scheme has been defined for a project, only authorized users can
open the project. Only users with the corresponding rights can modify the projects. The
following authorization types exist.
Type Description
Safety Administrator
(Sec Adm) Safety administrators can modify the user management scheme:
setting up, deleting, changing the PADT user management
scheme, and the user accounts and user groups, setting up the
default user account.
Furthermore, they can perform all SILworX functions.
Read and Write (R/W) All SILworX functions, except for the user management
Read only (RO) Read-only access, i.e., the users may not change or archive the
projects.
Table 26: Authorization Types for the PADT User Management Scheme
The user management scheme allocates the rights to the user groups. The user groups
allocates the rights to the user accounts assigned to it.
Characteristics of user groups:
ƒ The name must be unique within the project and must contain 1...31 characters.
ƒ A user group is assigned an authorization type.
ƒ A user group may be assigned an arbitrary number of user accounts.
ƒ A project may contain up to 100 user groups.
ƒ If the name of a user group is modified, it might happen that the controllers can no
longer be loaded by performing a reload.
Characteristics of user accounts:
ƒ The name must be unique within the project and must contain 1...31 characters.
ƒ A user account is assigned a user group.
ƒ A project may contain up to 1000 user accounts.
ƒ A user account can be the project default user
6.2 User Management for the Controller
The user management for a controller (PES user management) is used to protect the
HIMax controller against unauthorized access and actions. The user and its access rights
are part of the project; they are defined with SILworX and loaded into the processor
module.
The user management can be used to set and manage the access rights to a controller for
up to ten users. The access rights are stored in the controller and remain valid after
switching off the operating voltage.
Each user account is composed of name, password and access right. The user data can be
used to log in once a download has been performed to load the project into the controller.
The user accounts of a controller can also be used for the corresponding remote I/Os.
Users log in to a controller using their user name and password.
