8.2.2 Device Manager Object Services — The services provided by the Device Manager object are defined in
SEMI E54.1 [1]. The Device Manager object supports the additional services listed below.
Table 7 Device Manager Object Services
Service Service Identifier Type Description
Laser On S1 R Used to prompt the device to take the laser from the
LASER OFF state to LASER ON AND STABLE state as
defined by the Laser Status attribute.
Laser Off S2 R Used to prompt the device to take the laser immediately to
the LASER OFF state as defined by the Laser Status
attribute.
Reserved S3–S64 — Reserved for future expansion
Manufacturer Specified > S64 — Manufacturer Specific services
8.2.2.1 Laser On (Optional) — This service is used to prompt the device to take the laser from the LASER OFF
state through supported laser states 1 and/or 2, to state 3, as defined by the Laser Status attribute. If the laser turns on
successfully, a “success” response code is returned. If the sensor is missing or interlocked off, a “object state
conflict” error response is returned and the laser remains in the appropriate state.
8.2.2.2 Laser Off (Optional) — This service is used to prompt the device to take the laser to the LASER OFF state
immediately. If the laser turns off successfully, a “success” response is returned. If the sensor is in an interlocked
state, a “object state conflict” error response is returned and the laser remains in the interlocked off state.
8.2.3 Device Manager Object Behavior — The behavior exhibited by the Device Manager object is defined in
SEMI E54.1 [1]. Additional behavior is detailed below.
8.2.3.1 Device Manager EXECUTING State Behavior — Required sub-states within the EXECUTING state,
descriptions of these substates, and a transition matrix associated with these sub-states are given in Figure 2, Table
8, and Table 9 respectively.

Table 8 Device Manager Behavior EXECUTING Sub-State Description
State Description
EXECUTING Laser is in one of the following enumerated states as indicated in the Laser Status Device Manager
attribute: LASER INTERLOCKED (optional), LASER MISSING (optional), or LASER OFF. Device
will respond to Laser On and Laser Off services as appropriate to move between sub-states within the
EXECUTING and LASER ADDRESSABLE states.
LASER
ADDRESSABLE
Laser is in one of the following enumerated states as indicated in the Laser Status Device Manager
attribute: LASER OFF, LASER ON AND STABLE, LASER TURNING ON (optional), or LASER ON
BUT NOT STABLE (optional). Device will respond to Laser On and Laser Off services as appropriate
to move between sub-states within the LASER ADDRESSABLE state.
LASER OFF This is the entry sub-state to LASER ADDRESSABLE; Laser is Off; Laser Status Device Manager
attribute is in the enumerated state: LASER OFF. Device is not performing the “counting” process.
(See NOTE 1.)
LASER ON AND
STABLE
Sub-state of LASER ADDRESSABLE; device is “counting” (See NOTE 1); Laser Status Device
Manager attribute is the enumerated state: LASER ON AND STABLE. Laser is performing the
“counting” process.
LASER
INTERLOCKED
Laser is Interlocked off; Laser Status Device Manager attribute is in the enumerated state: LASER
INTERLOCKED. Device is not performing the “counting” process. (See NOTE 1.) Sensor may or may
not be missing. Device cannot move to the LASER ADDRESSABLE or SENSOR MISSING states
until the interlock is removed.
SENSOR
MISSING
Laser sensor is missing; Laser Status Device Manager attribute is in the enumerated state: SENSOR
MISSING. Device is not performing the “counting” process. (See NOTE 1.) Device cannot move to the
LASER ADDRESSABLE state until the sensor is replaced.
LASER NOT OFF Laser is in one of the enumerated states as indicated in the Laser Status Device Manager attribute:
LASER TURNING ON (optional), LASER ON AND NOT STABLE (optional), or LASER ON AND
STABLE. Device will respond to Laser Off service as appropriate to move between sub-states within
the LASER ADDRESSABLE state.
LASER
TURNING ON
An optional sub-state of LASER NOT OFF. This is a conditional entry sub-state to LASER NOT OFF.
Device is preparing to turn on. Device is not performing the “counting” process. (See NOTE 1.)
LASER ON Laser is in one of the enumerated states as indicated in the Laser Status Device Manager attribute:
LASER ON AND NOT STABLE (optional) or LASER ON AND STABLE. Device will respond to
Laser Off service as appropriate to move between sub-states within the LASER ADDRESSABLE
state.
LASER ON AND
NOT STABLE
Sub-state of LASER ON; device is not “counting” (See NOTE 1); Laser Status Device Manager
attribute is the enumerated state: LASER ON AND NOT STABLE. Laser is not performing the
“counting” process.
NOTE 1: The “counting” process is defined in Section 8.8.3.1.
