7.5.4.2 Sensor, Actuator, Controller (SAC) Object –– The SAC object is the device component responsible for
coordinating the interaction of the device with the sensory/actuation/control environment as defined in the CDM
standard. Attribute values including SAC state are also as same as defined in the CDM standard. The presentation of
object instance attributes to the A-LINK network shall be as indicated in Table 3.

7.5.4.3 Assembly Object (Asm) –– The Assembly (Asm) object instances may be used to provide for grouping more
than one attribute from one or more object instances as defined in the CDM standard. Attribute values are also as
same as defined in the CDM standard. The presentation of object instance attributes to the A-LINK network shall be
as indicated in Table 4.

7.5.4.4 Local Link Object (Lnk) –– The Local Link (Lnk) object instances may be used to ‘link” an attribute of one
object instance to an attribute of another object instance as defined in the CDM standard. Attribute values are also as
same as defined in the CDM standard. The presentation of object instance attributes to the A-LINK network shall be
as indicated in Table 4.

7.5.4.5 Active Element (AE) Class –– The AE class is an abstract class generic to any device component as defined
in the CDM standard. Attribute values including AE state are also as same as defined in the CDM standard. The
presentation of object instance attributes to the A-LINK network shall be as indicated in
7.5.4.6 These attributes are inherited by any sensor, actuator and controller objects, and such further derived objects
as Sensor-AI and Actuator-BO objects.

7.5.4.7 Sensor (S) Class –– The S class is an abstract class generic to any sensors on device component as defined
in the CDM standard. Attribute values are also as same as defined in the CDM standard. The presentation of object
instance attributes to the A-LINK network shall be as indicated in Table 7. These attributes are inherited by any
sensor objects as Sensor-AI object. They also inherit AE class attributes. Attribute identifiers on A-LINK for such
direct and indirect inheritor classes of S class as Sensor-AI are assigned as ¶7.5.3.2 and Data Exchange
communication could give alternative access for the attributes.

7.5.4.8 Actuator (A) Class –– The A class is an abstract class generic to any actuators on device component as
defined in the CDM standard. Attribute values are also as same as defined in the CDM standard. The presentation of
object instance attributes to the A-LINK network shall be as indicated in Table 8. These attributes are inherited by
any sensor objects as Actuator-AO object. They also inherit AE class attributes. Attribute identifiers on A-LINK for
inheritor classes Sensor-AO are assigned as ¶7.5.3.2 and Data Exchange communication could give alternative
access for the attributes.

7.5.4.9 Controller (C) Object –– The C object contains structure and behavior common to all controller element
instances on device component as defined in the CDM standard. Attribute values are also as same as defined in the
CDM standard. The presentation of object instance attributes to the A-LINK network shall be as indicated in
Table 9. It inherits AE class attributes.

7.6 Services
7.6.1 A-LINK specifies standard mechanisms for the communication of data over the network. These mechanisms
are used to communicate attributes specified in the device on the A-LINK. Also they are used to request instructions
specific for component in the device on the A-LINK.
7.6.2 Service Requests and Response
7.6.2.1 The A-LINK attribute communications and instructions require specific definitions. They are described in
the following sections.
7.6.2.1.1 Service Request and Response Protocol
7.6.2.1.1.1 All service request messages, except Get_Attribute and Set_Attribute, are sent to a device using
Directive service functions of A-LINK. The responses to these message requests are specified by A-LINK.
7.6.2.1.1.2 The Service Request message is formatted, as defined by A-LINK, with the following information:
Location := Object ID
7.6.2.1.1.3 This service request message has no other information requested with the message. Response of the
request has following information:
Location := Object ID
Status := Response Information
NOTE 2: The Location information for the response message is optional (conditional) information. Representation of the Status
information is implementation specific. The Response Information is dependent on class and/or device. However if the first item
of the response information, i.e. Response Code, is zero, it always means successful. Additional data may follow.
