On the medium HMI display, the single line diagram can be presented and
shows apparatuses that can be controlled locally using the control buttons.
To safeguard the interests of our customers, both the IED 670 and the tools that
are accessing the IED 670 are protected, subject of authorization handling. The
concept of auhtorization, as it is implemented in the IED 670 and the associated
tools is based on the following facts:
•
There are two types of points of access to the IED 670:
1. local, through the local HMI
2. remote, through the communication ports
•
There are different levels (or types) of users that can access or operate different areas
of the IED and tools functionality; the pre-defined user types are defined as follows:
The IED users can be created, deleted and edited only with the User Manage-
ment Tool (UMT) within PCM 600. The user can only LogOn or LogOff on
the LHMI of the IED, there are no users, groups or functionalities that can be
defined on the IED LHMI.
The display time out is set to 60 minutes at delivery. At delivery the default user
is the SuperUser. No LogOn is required to operate the IED until a user has been
created with the UMT. See Application manual for more details.
