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
of the EPD device with the sensory/actuation/control
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
contains the additional attributes required for the Sensor
Actuator Controller object.

8.3.2.1 Reset Endpoint (Optional) — This service is used to instruct all of the Sensor-BI-TH-EP objects to perform
a ‘Reset’ of their endpoint monitoring and measuring events. A one-time reset of their respective Sensor-BI-TH-EP
attributes is performed. There are no parameters required for this service.
8.3.2.2 Download Recipe (Optional) — This service is used to set the recipe parameters associated with the
endpoint sensor or a specific Sensor-BI-TH-EP object. The format and type of data comprising recipe data and the
mechanism implemented to interrupt recipe data and distribute its contents to the appropriate Sensor-BI-TH-EP
object is manufacturer specific. The parameter ‘Recipe Data’ may be a formatted data structure or a list of individual
data items. The following table describes the parameters specified for this service.
