8.4.1 Sensor-BI-TH Object Attributes — The attributes provided by the Sensor-BI-TH object are defined in SEMI
E54.1. There are no additional attributes required for the Sensor-BI-TH object.
8.4.2 Sensor-BI-TH Object Services — The services provided by the Sensor-BI-TH object are defined in SEMI
E54.1. There are no additional services required for the Sensor-BI-TH object.
8.4.3 Sensor-BI-TH Object Behavior — The behavior exhibited by the Sensor-BI-TH object is defined in SEMI
E54.1. There is no additional behavior required for the Sensor-BI-TH object.
8.5 Sensor-BI-TH-EP Object — T he Sensor-BI-TH-EP (Endpoint) object inherits the attributes, services, and
behavior of the Sensor-BI-TH as defined in SEMI E54.1. The Sensor-BI-TH-EP is the device component
responsible for retrieving a reading, or readings, from the device specific signal-processing sensors, optionally
processing the readings with a manufacturer specified algorithm, or algorithms, and then making the endpoint result
available through the “Value” attribute.
8.5.1 Sensor-BI-TH-EP Object Attributes — The attributes provided by the Sensor-BI-TH object are defined in
SEMI E54.1. The Sensor-BI-TH object attribute content and its attribute extensions to support the Sensor-BI-TH-EP
object are listed in the table below.

NOTE 1: “*” Indicates that the specific attribute is nonvolatile. Nonvolatile requires that the current attribute value be maintained through a
component power cycle.
8.5.1.1 Value — The attribute that maintains the current endpoint event result. The value of the ‘Value’ attribute is
read as a Boolean (True or False) endpoint detection event result.
8.5.1.2 Reading Valid — An attribute which specifies whether the “Value” attribute contains a valid value. This
attribute is Boolean that can take on one of the following values:
0 = INVALID
1 = VALID
NOTE 3: The ‘Reading Valid’ attribute is identified as an optional attribute of the SBITH object class but is identified as a
required attribute for the SBITHEP object class.
8.5.1.3 State — An attribute that records the current state of the endpoint object. This attribute is an enumerated
byte. The possible enumeration and the requirement for support are as follows:
0 = ENDPOINT OFF (required)
1 = ENDPOINT IN PROCESS (required)
2 = ENDPOINT IDLE (optional)
3 = ENDPOINT SUSPENDED (optional)
4 = ENDPOINT FAILURE (optional)

5-63 = Reserved
64-255 = Manufacturer Specified (optional)
8.5.1.4 Status — An attribute which s pecifies whether endpoint detection event reporting is active based upon the
services ‘Endpoint On’, ‘Endpoint Start’, and ‘Endpoint Off or On’. This attribute is an enumerated byte that can
take on one of the following values:
0 = Endpoint Off
1 = Endpoint On
8.5.1.5 Minimum Time — An attribute that specifies the minimum time in milliseconds for an endpoint detection
event. No attempt to report an endpoint detection event will take place until the minimum time specified has
expired.
8.5.1.6 Maximum Time — An attribute that specifies the maximum time in milliseconds for an Endpoint detection
event before an alarm is reported.
8.5.1.7 Target Time — An attribute that specifies the expected time in milliseconds for an Endpoint detection
event.
8.5.1.8 Elapsed Time — An attribute that specifies in milliseconds the amount of time that has elapsed since the
beginning of the current endpoint detection event. This attribute will behave as a count up timer that is frozen when
the endpoint event is detected.
8.5.1.9 Time Stamp — An attribute that specifies the time when the endpoint detection event completed.
8.5.1.10 Recipe Identifier — An attribute that specifies a manufacturer specific endpoint algorithm or algorithms to
be utilized to determine the current endpoint detection event. The interpretation of this attribute is manufacturer
specific.
8.5.1.11 Step Identifier — An attribute that specifies a process recipe step that is associated with the current
endpoint detection recipe and/or event. The interpretation of this attribute is manufacturer specific.

8.5.2 Sensor-BI-EP Object Services — The services provided by the Sensor-BI-EP are inherited from the Sensor-
BI object defined in SEMI E54.1. The Sensor-BI-EP object supports the additional services listed in Table 15 below.

Type Description
Endpoint On S1 R Used to prompt the endpoint object to go from the ENDPOINT OFF state to
ENDPOINT ON/ENDPOINT IDLE state as defined by the State and Status
attribute.
Endpoint Off S2 R Used to prompt the endpoint object to go immediately to the ENDPOINT OFF state
as defined by the State and Status attribute. All endpoint detection processes are
aborted and all active timers are stopped.
Endpoint Start S3 R Used to prompt the endpoint object to go from the ENDPOINT OFF or ENDPOINT
IDLE (optional) state to the ENDPOINT IN PROCESS state and begin the endpoint
detection event process.
Endpoint
Suspend
S4 R Used to prompt the endpoint object to go to the ENDPOINT SUSPENDED state
from the ENDPOINT IN PROCESS state. All endpoint detection event processes
and active timers are suspended.
Endpoint
Resume
S5 R Used to prompt the endpoint object to go from the ENDPOINT SUSPENDED state
to the ENDPOINT IN PROCESS state. All endpoint detection event processes and
active timers resume from where they were suspended.

8.5.2.1 Endpoint On (Required) — Th is service is
used to prompt the endpoint object to go from the
ENDPOINT OFF state to the ENDPOINT ON /
ENDPOINT IDLE state as defined by the State
attribute. If the device does not support the ENDPOINT
IDLE state then the endpoint object goes immediately
to the ENDPOINT ON / ENDPOINT IN PROCESS
state. If the State attribute is already set to ENDPOINT
IDLE or ENDPOINT IN PROCESS, the endpoint
object is set to the appropriate state. If the device turns
on successfully, a “success” response is returned. If the
device fails to turn on properly, a “fail” response is
returned and the endpoint object remains in the
appropriate state.
8.5.2.2 Endpoint Off (Required) — This service is
used to prompt the endpoint object to go immediately to
the ENDPOINT OFF state from the ENDPOINT ON
state as defined by the State attribute. All endpoint
detection event processes are aborted and all active
timers are stopped. If the state attribute is already set to
ENDPOINT OFF, the endpoint object remains in the
appropriate state. If the device turns off successfully, a
“success” response is returned. If the device fails to turn
off properly, a “fail” response is returned and the
endpoint object remains in the current state.
8.5.2.3 Endpoint Start (Optional) — T his service is
used to prompt the endpoint object to go from the
ENDPOINT OFF or ENDPOINT IDLE state to the
ENDPOINT IN PROCESS state and begin the endpoint
detection event process with the initial endpoint
attribute parameter values. If the State attribute is not
currently in the ENDPOINT OFF or ENDPOINT IDLE
state, an “object state conflict” error response is
returned and the endpoint event remains in the
appropriate state.
8.5.2.4 Endpoint Suspend (Optional) — This service is
used to prompt the endpoint object to go from the
ENDPOINT IN PROCESS state to the ENDPOINT
SUSPENDED state and suspend the endpoint detection
event process. All active timers are suspended and held
at their current values. If the State attribute is not
currently in the ENDPOINT IN PROCESS state, an
“object state conflict” error response is returned and the
endpoint object remains in the appropriate state. The
Endpoint Suspend service is conditional on the
Endpoint Resume service being supported.
8.5.2.5 Endpoint Resume (Optional) — This service is
used to prompt the endpoint object to go from the
ENDPOINT SUSPENDED state to the ENDPOINT IN
PROCESS state and resume the endpoint detection
event process. The process resumes using the endpoint
attribute parameter values and timer readings that were
saved when the endpoint was suspended by the
Endpoint Suspend service request. If the Endpoint
Resume service is issued while the State attribute is not
in the ENDPOINT SUSPENDED state, an “object state
conflict” error response is returned and the endpoint
event remains in its existing state. The Endpoint
Resume service is conditional on the Endpoint Suspend
service being supported.
8.5.3 Sensor-BI-TH-EP Object Behavior — The
behavior exhibited by the Sensor-BI-TH-EP object is
