-
Attribute. Enter the PLC variable attribute.
-
Object Name. Enter the BACnet object name. Use a
meaningful description, such as Damper Angle.
-
Object Type. Click on the field and select the relevant
object type for the PLC tag:
-
Object ID. This is the BACnet object instance. Valid
range is from 0 to 63, which means you can define 64
object instances of each object type. Each object is
uniquely defined by object-instance and type. Support is
provided for 256 BACnet objects. Click on the field and
type in the ID value.
-
Present Value. Not editable (from user interface). When
the BACnet module requests the PLC report a specific
value, the PLC returns the present value in the specific
index. Example: When the PLC receives a BACnet
command to report the present value of Analog Value
Index 1, the PLC sends the present value of AV 1 back
to the requester. This value is displayed in the Present
Value column.
