Overview Table of BACnet Object Types

A BACnet object type equates to a WinCC OA datapoint type. After the import of the BACnet datapoint list, the datapoint types (object types) are automatically created in the WinCC OA PARA. The object type defines the complexity of an object, e.g. data type, number of possible states, properties, etc.

A BACnet object equates to a WinCC OA datapoint. An object is imported from a BACnet device or EDE file and can be created in WinCC OA as a datapoint subordinated to the corresponding datapoint type.

A WinCC OA datapoint represents the data/information (BACnet properties) of an object by its WinCC OA datapoint elements.

For information on faceplates, tabs, symbols and the value input panel see Symbols and Faceplates - General.

Note:

The BACnet norm does not define whether a property is read-, write- or read/write-able. Due to this fact, the BACnet Add-on uses common predefinition that is set using the configuration of the master datapoint inside the ASCII file BACnet_All.dpl. The settings can be changed through adaptation of the configuration.

BACnet Objects


Datapoint Type / BACnet Object Type	Object Type ID	Brief Description
BACnet_AI	0	Analog input. Defines a standard object whose properties represent the externally visible characteristics of an analog input.
BACnet_AO	1	Analog output. Defines a standard object whose properties represent the externally visible characteristics of an analog output.
BACnet_AV	2	Analog value. Defines a standard object whose properties represent the externally visible characteristics of an analog value.
BACnet_BI	3	Binary input. Defines a standard object whose properties represent the externally visible characteristics of a binary input.
BACnet_BO	4	Binary output. Defines a standard object whose properties represent the externally visible characteristics of a binary output.
BACnet_BV	5	Binary value. Defines a standard object whose properties represent the externally visible characteristics of a binary value.
BACnet_MSI	13	Multi-state input. Defines a standard object whose Present_Value (present value) can take integer values.
BACnet_MSO	14	Multi-state output. Defines a standard object whose output is an integer value.
BACnet_MSV	19	Multi-state value. Defines a standard object whose properties represent the externally visible characteristics of a multistage value.
BACnet_Accumulator	23	Addition of impulse data of measurement devices over the time. Used for balancing, statement and energy performance management (for interval mass counter see Pulse Converter).
BACnet_Calendar	6	Calendar. Defines a standard object that is used to define a list of calendar entries (date list).
BACnet_Schedule	17	Time plan. Defines a standard object that is used to define a periodic timeplan, also with optional exceptions on arbitrary days or on arbitrary dates, which can recur within a certain period of time.
BACnet_NOC	15	Alarm class. Defines a standard object that contains the necessary information for the distribution of event alarms with BACnet systems.
BACnet_Program	16	Object for program controlling in a BACnet device (e.g. load and start).
BACnet_PulseConverter	24	Object for impulse conversion for mass counting in defined time intervals.
BACnet_TrendLog	20	Trend Log. Archives a property of a referenced object and, when predefined conditions are met, saves the value of the property and a timestamp in an internal buffer for subsequent retrieval.
BACnet_Device	8	BACnet device. Defines a standard object whose properties represent the externally visible characteristics of a BACnet device.
