Server Object Instance
No
: This property defines the object instance number of the
underlying BACnet server object.
Server Object Description
: This property defines the object description of the
underlying BACnet server object. It can be left blank.
Server Object Device Type
: This property defines the object device type of the
underlying BACnet server object. It can be left blank.
Server Accumulator Offset Correction
: This property is available for accumulator
objects only. It is activated as a default. It ensures that the written data point value is
corrected in the Present_Value as soon as the Value_Set property is written and
requests a certain Present_Value. That correction offset is then added to the written
data point value, e.g., when received over a connection.
Get Active Priority
: Set this check box to let the data point reflect the active priority
of the local or remote BACnet object. The priority is a number between 1 and 16. This
property is only applicable for commandable BACnet objects.
Allocate Server Object
: This Boolean property defines, if a server object shall be
allocated for the data point. This option is useful, when a local server object shall be
allocated for a client mapping.
Allocate Client Mapping
: This Boolean property defines, if a client mapping shall be
allocated for the data point. This option is always set, if at least on client mapping is
attached.
Client Map Count
: This property defines the number of client mappings attached to a
data point. A data point can have one read client map or
n
write client mappings.
Client Map [n]
: This is a list of client mappings. The property shows a summary of the
client mapping parameters.
Client Confirmed COV
: This Boolean property defines, if a client map subscribes
with the confirmed COV service. If not enabled, the unconfirmed COV is used.
Client Map Type
: This property determines the type. It can be one of the following:
Poll, COV, Auto, Write, or Value (see Section 6.6.1).
Client Write Priority
: For a write or value client map, this property defines which
priority is used for writing.
Remote Instance Number
: This property specifies the object instance number of the
remote server object. The object type cannot be edited.
Value Read Mode
: For value client mappings, this property defines the read mode:
Poll, COV, or Auto.
7.7.11 User Registers
User registers are data points on the device that do not have a representation on the
network. Thus, they are not accessible over a specific technology. A register merely serves
as a container for intermediate data (e.g., results of math objects). Since a register has no
network direction, it can be written and read. Therefore, it is created as a value data point.
For back-ward compatibility, it is still possible to generate two data points for each register,
one for writing the register (output) and one for reading the register (input).
