currentStateName The Parameter, if any, that can be accessed to determine
the current state within the identified StateMachine.
Zero or one element of type Parameter,
described in Section 10.4 .
previousStateName The Parameter, if any, that can be accessed to determine
the previous state within the identified StateMachine.
Zero or one element of type Parameter,
described in Section 10.4 .
eventMaps The events defined by this StateMachine, and the
Parameters that are available for reporting with those
events.
One or more elements of type
EventToParameterMap, described in
Section 10.8.6.5 . There shall be one
such map for each event defined in the
identified StateMachine.
nestedStateMachines Any nested state machines defined within the identified
StateMachine.
One or more elements of type
StateMachineInstance. Although it is
possible to create more, only one level
of nesting of the StateMachineInstance
class is required to describe arbitrary
levels of nesting described by the
referenced top-level StateMachine.
10.8.6.5 EventToParameterMap — This class is used to provide a list of the Parameters available for a specific
event from a given StateMachine.

10.8.6.7.1 availableParameters — All transient Parameters (see Section 10.4.11) that are available for reporting
with an event generated by the entity providing the EventToParameter map shall be provided in this list. It is not
necessary to list any non-transient Parameters via this association. Non-transient Parameters are implicitly available
for reporting with any event.
10.8.6.8 Events may only be defined within the context of a Transition between two States within a StateMachine.
All events that the equipment can generate must have a StateMachine defined for them. It is not necessary to define
multiple StateMachines for a situation in which the same kind of events are generated by multiple sources.

10.8.6.10 SEMI Standard Events
10.8.6.10.1 name — If the Event represents a SEMI standard event, the value of this attribute shall be a URN of the
form: “urn:semi-org:event:<standard id>:<state machine>:<transition number>:<event name>”.
10.8.6.10.1.1 <standard id> shall be a string formatted according to the SEMI standard form for representing a
specific version of a standard document (for example, “E87-1101”), no spaces, upper-case alphanumeric characters
and hyphens only.
10.8.6.10.1.2 <state machine> shall be the name of the state machine in which the event is defined. If no such state
machine is defined, this field shall be equal to the text “None”. If there is a defined state machine, the name shall be
equal to the state machine name as it appears in the standard, with each word in the name concatenated. The state
machine name shall use the camel case capitalization convention (that is, only the first letter of each word in the
state machine name is capitalized). For example, the state machine name for the SEMI E87 LOAD PORT
TRANSFER state machine would be “LoadPortTransfer”.
10.8.6.10.1.3 <transition number> shall be a string representation of the transition number as it appears in the state
machine definition. If no state machine or transition number is defined in the standard, this field shall be equal to
the text “None”.
10.8.6.10.1.4 <event name> shall be the name of the event as it appears in the standard with no spaces,
alphanumeric characters only, using camel case capitalization. If no event name is defined, this field shall be
formed by concatenating the names of the source and target states for the <transition id>, separated by a hyphen.
The state names shall have no spaces, alphanumeric characters only, and use camel case capitalization. If either of
these states is an “initial” or “final” state, the words “Initial” or “Final”, respectively, shall be used for the state
name. For example, the event name for the E87 load port transfer history transition from the initial state to “OUT
OF SERVICE” would be “Initial-OutOfService”.

transitions The transitions to which this event is mapped. One or more elements of type Transition.
10.9 ObjTypes
10.9.1 Figure 21 shows how to describe SEMI ObjTypes (for example, the “Carrier” ObjType from SEMI E87) that
have been implemented by the equipment. An ObjType is similar to a class in that it describes attributes and state
machines that are common to all instances of the ObjType. Each ObjType instance maintains its attributes and state
machines independently of all other instances of the same ObjType. See Related Information 6 for examples using
the SEMIObjType class.

Describing Implemented SEMI ObjTypes
10.9.1.1 SEMIObjType — This class describes the attributes and events for a SEMI ObjType that has been
implemented by the equipment. If it is a SEMI standard ObjType then it is identified by the name of the SEMI
standard within which it was defined, and the name of the ObjType specified in that standard. Each ObjType
includes at least two attributes, corresponding to its type name and its instance id (see SEMI E39).

standardVersion The complete SEMI standard version number for
the document where the ObjType is defined, if
applicable.
Y Text, using the SEMI standard form for
representing a specific version of a
standard document (for example, “E87-
1101”), no spaces, upper-case
alphanumeric characters and hyphens
only. If not a SEMI standard ObjType,
then this attribute shall be empty.
objType The name of the SEMI objType. Y Text. Named using identical spelling and
case as the documented objType in the
corresponding standard.

ObjType instance.
