Guidelines For Defining Scope Of Responsibility - Honeywell Experion LX Client Manual

Enterprise models
Details of a server's point counts are available on the Server License Details display (see the
topic titled "Checking your Experion license" in the "Configuration overview" section of the
Station Configuration Guide).
Develop a systematic and user-friendly naming convention for your assets
You need to develop a systematic and user-friendly naming convention, which complies with
the naming rules for assets. A well-designed naming convention makes it much easier for
operators to navigate their way through your system, and to respond to alarms.
A systematic naming convention is also essential if you want to make use of generic
displays—for example, use the same display for every holding tank in your plant.
Define appropriate assets as assignable assets
An assignable asset is one that can be assigned to an operator or Station for the purposes of
scope of responsibility.
As a general rule, we recommend that you restrict assignable assets to the two top levels of
your asset model. (By default, assets at the top level are assignable.)
If you make a lower level asset assignable, you should, for the sake of simplicity, also make
all its ancestors assignable. Otherwise, it may be harder to understand the behavior of the
assignment displays.
An asset model must not include more than the maximum number of assignable assets, which
is documented in the Experion Specification.
You should only change an asset from assignable to non-assignable (or from non-assignable
to assignable) before you engineer your data points. If you make such a change after you
have engineered your data points, you will need to reconfigure your scope of responsibility
displays.

Guidelines for defining scope of responsibility

It is essential that you define scope of responsibility (SOR) so that operators can access those
parts of the system for which they are responsible.
Experion system security comprises oth:
Windows operating system security
n
Station security: Station-based or operator-based
n
System security enables you to control who has access to the system and to control what users
can do within the system when access is granted.
