7 Conventions
7.1 This document embraces the c onventions and
notations stated in section 6 of SEMI E54.1.
8 Device High Level Structu re
8.1 General Description
8.1.1 The high-level object view of an Endpoint
Device (EPD) profile is shown in Figure 1.
8.1.2 Note that the profile for an “EP D Device” object
is depicted in Figure 1 only for the purposes of
illustrating a high level view of the device and its
component objects. In the context of this document, this
object is not addressable, does not have addressable
attributes, does not have accessible services and, does
not exhibit any defined behavior.
8.1.3 In the remainder of this section , this document
defines in detail the component objects unique to the
EPD device. References, rather than definitions, are
included for the DM, the SAC and other objects defined
in SEMI E54.1.
8.1.4 Many of the objects defined in this document
inherit properties from other objects. The properties
inherited include attribute, service and behavior
definitions. These other objects are specified here or in
SEMI E54.1.
8.1.5 This document provides for future extensions as
well as manufacturer specific enhancements by
reserving object attribute identifiers and object service
identifiers. Specifically all object definitions in this
document specify or reserve the first 64 attribute
identifiers (A1 through A64) and the first 64 service
identifiers (S1 through S64) allowing manufacturers to
specify identifiers beyond these ranges. Additionally,
byte enumerated attributes are specified or reserved
from 0 to 63 allowing manufacturers to specify an
enumeration beyond this range (64 to 255).
8.1.6 Endpoint Device (EPD) Description — An
Endpoint device profile is composed of the component
objects and object relationships shown in Figure 1.

NOTE 1: The Sensor-BI-TH, DM, SAC, and Assembly are defined in the CDM. Additional attributes and services are added to
support the EPD.
NOTE 2: Assembly-EPD #1 object is required. Other Assembly-EPD objects are optional.

8.1.7.2 Object Services — Not all object services listed in this document can necessarily be requested over the
network. They are included in this document because their behavior may generate network activity.
8.1.7.3 Object Behavior — A network specific service error response is generated for all service requests received
over the network that are not supported by the object, or contain a parameter value which is beyond the supported
range, or which is otherwise invalid.
8.2 Device Manager Object (DM) — The Device Manager object is the device component responsible for
managing and consolidating the device operation as specified in SEMI E54.1. The following sections specify the
components of the DM object that are not specified in the Common Device Model or require further definition than
specified in SEMI E54.1.
8.2.1 Device Manager Object Attributes — Required and optional DM object attributes are listed in Table 3.

8.2.1.1 Device Type — An attribute th at uniquely identifies the type of the device on the network. The device type
attribute is assigned as follows:
Endpoint Device = “EPD”
NOTE 2: If the “Endpoint Device” functionality is implemented by another Sensor/Actuator Network Specific Device Model, the
‘Device Type’ attribute value may be specified by the manufacturer to identify the other Specific Device Model.
8.2.1.2 Exception Detail Alarm (Optional) — An attribute that identifies the detailed alarm status of the device.
Table 4 defines the bit assignments associated with the alarm exception detail.

8.2.2 Device Manager Object Services — The services
provided by the Device Manager object are defined in
SEMI E54.1. There are no additional services required
for the Device Manager object.
8.2.3 Device Manager Object Behavior — The
behavior exhibited by the Device Manager object is
defined in SEMI E54.1. There is no additional behavior
specified for the Device Manager object.
8.3 Sensor Actuator Controller Object (SAC) — The
Sensor Actuator Controller object is the device
component responsible for coordinating the interaction

environment as specified in SEMI E54.1. The following
sections specify the components of the SAC object that
are not specified in the Common Device Model or
require further definition than specified in the Common
Device Model.
8.3.1 Sensor Actuator Controller Object Attributes —
The attributes provided by the Sensor Actuator
Controller object are defined in SEMI E54.1. Table 7
