7.1.4 An embodiment of a specific device type
represented as an aggregation of the object types listed
in Table 2 that is compliant with both the CDM
specification and the Modbus/TCP specification, is a
candidate for a SEMI SDM as well as a Modbus/TCP
device definition. Conversely, all SEMI SDM’s and
Modbus/TCP device definitions specified for operation
over a SEMI compliant Modbus/TCP network must be
an aggregation of the object types listed in Table 2, and
be compliant with both the CDM specification and the
Modbus/TCP standard specifications.
7.1.5 In the following sections the presentation to the
network of object addressing, object attributes, and
object services for each of the object types listed in
Table 2 is described in detail. Refer to the CDM
standard to determine if the object instance attribute and
service is specified as required or optional. Unless
otherwise noted, all attributes and services described
are instance level attributes (as opposed to class level
attributes). A class level attribute and service is
accessed as instance number zero.
NOTE 3: The formats of object attributes and services are
detailed in the CDM document; the presentation of object
attributes and services to the Modbus/TCP over a TCP/IP
network is detailed in the tables contained in the following
sub-sections and in the Modbus/TCP standard specifications.
7.2 Device Manager (DM) Object
The DM object
instance is the device component responsible for
managing and consolidating the device operation. Each
device must support one (and only one) DM object.
The DM object as well as its common required and
optional attributes, services and behavior are described
in the CDM standard. The presentation of object
instance attributes and services to the Modbus/TCP
network shall be as indicated in Table 3. Note that all
service ID values identified refer to the ID of the
request or notification component of that service.
Corresponding reply components to request/reply
services shall have a service ID value equal to the
request component ID plus one.

7.3 Sensor, Actuator, Controller (SAC) Object –– The
SAC object instance is the device component respons-
ible for coordinating the interaction of the device with
the sensory/actuation/control environment. Each device
must support one (and only one) SAC object instance.
The SAC object instance as well as its common
required and optional attributes, services, and behavior
are described in the CDM standard. The presentation of
object instance attributes and services to the
Modbus/TCP network shall be as indicated in Table 4.

7.4 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 in a device into a single data structure for
communication over the Modbus/TCP network. The
presentation of object instance attributes and services
shall be as indicated in Table 5.

one object instance to an attribute of another object
instance. Refer to the CDM for further explanation and
use of this object. The presentation of object instance
attributes and services are as indicated in Table 6.
