Access control

Access control
Operator input is allowed without restriction if no users are configured.
The following settings or functions are performed, depending on the logged on user and the
authorization levels configured for SFC Visualization:
● Operator input buttons are activated or deactivated.
● Operator input is subject to verification.
This input is either accepted or discarded, depending on the result.
● The change of the allocation status of equipment modules. The "Allocation" operation of
the "Higher process controlling" authorization level is required to perform this change.
The authorization levels set on the Engineering Station are transferred to the OS server (OS
> Load target system), where they are used in runtime operation.
● Global and SFC-specific authorization levels can be configured on an OS server. However,
these are overwritten the next time the function OS > Load target system is used. If SFC-
specific authorization levels exist on the OS server, these are used at runtime. If no SFC-
specific authorization levels are configured, the global authorization levels of the OS server
are used.
● On an OS multiclient, only SFC-global authorization levels can be configured. If SFC-
specific authorization levels exist on the OS server, these are used at runtime. If no SFC-
specific authorization levels are configured, the global authorization levels of the OS
multiclient are used.
● An OS Web Server does not have its own authorization levels. The relevant authorization
levels are transferred depending on whether it is an OS multiclient or an OS server.
● An OS Web Client does not have its own authorization levels. The authorization levels of
the OS Web server are used at runtime.
Note
If button or a setpoint is not enabled although the user has the necessary operator
authorization, then operation may be disabled on the block (for instance ENSTART = 0).
