  • "Object access level" is a configuration property which can only be set up offline (ABT, application configuration).
  • "Object access level" is evaluated by client applications such as Technical Operator, DB-Import, and APOGEE Point Team mapping.

Object usage ✳

 

 

"Object usage" indicates whether the object is used or unused. The "Object usage" property can hide or display respective objects and their functionality in a client. For example, room functionality can be marked for flexible room arrangements as used/unused. An object that is marked as unused behaves as if the object does not exist.

"Object identifier" is a numeric code that is used to identify the object. It must be unique internetwork-wide.

Object name

 

 

"Object name" represents a name for the object that is unique internetwork-wide. The minimum length of the string is one character. The set of characters used in the "Object name" are restricted to printable characters.

Object type

 

 

"Object type " indicates membership in a particular object type class. E.g. "Analog input", "Binary output", "Event enrollment", "Trend log", etc.

Building automation profile ✳

 

 

"Building automation profile" is an enumeration that indicates a particular type of Siemens proprietary object. Siemens objects are based on standard BACnet objects. For example, Siemens Analog Input, Analog Output, Analog Calculated Value, and Analog Configuration Value are based on standard Analog Input, Analog Output, and Analog Value BACnet objects.

Profile name

 

 

"Profile name" indicates the name of an object profile to which this object conforms. To ensure uniqueness, a profile name must begin with a vendor identifier code followed by a dash. All subsequent characters are administered by the organization registered with that vendor identifier code.
