completion of
Standby transition by
MESFactory.
STANDBY MESFactory is in
STANDBY state event
published by the instance of
MESFactory.
All component managers,
machines and material are
idle and in a safe state.
6 STANDBY void makeOperating

MESFactory
OPERATING void startup ( ); sent to an
instance of Component-
Manager.
Since standby means nearly
available for immediate
use, this startup transition
should be minimal.

As an action, messages
delegated to component
managers. The Resource
inherited interface also
implements

6.7.4 Area Interface
Module: FactoryOperations
Interface: Area
Inherited Interface: OwnedEntity
Description: Area is the interface corresponding to a physical or logical grouping of factory resources
(the complement of machines and/or personnel assigned to it). Area may represent a
singular entity or it may represent a collection of other Areas. For example, an Area may
represent an entire facility for maintenance purposes, or an Area may represent a
processing area such as a “bay” which is comprised of “zones.”
SEMI E97-0200A © SEMI 200037
The association between an Area and its composite Areas may be hierarchical or there
may simply be a collection of peer Areas without any explicit or implicit relationship.
Area may or may not be an optional construct, depending on such issues as security.
