The read access level can be defined and changed in CARE only. In the Excel Web
HTML Interface, the read access level is displayed only.
The read access level assigned to a datapoint determines which user level can read
values (properties) of that particular datapoint on the Excel Web HTML Interface.
A user who has a user level equal to or higher than the assigned read access level
of the datapoint, will have this access right enabled in the Excel Web HTML
Interface, all others will not (for further details, please refer to the User
Administration section).

The reference property of a reference input point provides the source (BACnet
object) which passes the value to the reference input point. The reference property
of a reference output point provides the source (BACnet object) which passes the
value to the reference output point.
Sources can be any point of any Excel Web controller and 3
of the project.
Reference points are a type of software point that can share point information
across plants. If plants are located in different controllers, the point information will
be automatically transferred across the BACnet bus.
Reference input points receive information from a point in another plant of the same
controller (internal reference) or of another plant in another controller or 3
device (external reference). Controllers and 3
same or in different projects (for detailed procedure see CARE User Guide EN2B-
0182GE51).
Each reference input is associated with a physical or value datapoint (source point)
somewhere in a plant residing in a controller on the bus. The source point cannot be
a receiver point and source point and receiver point cannot reside in the same plant.
