3.8 Terminology
The following terms are used throughout the document to refer to the various entities interfacing with the 7AF:
Equipment
The 7AF.
Operator
The person who physically has access to the equipment's material port(s) and control panel.
This is the person who is operating the 7AF.
Host
The computer which is connected to the equipment via the SECS interface
3.9 State Diagrams
This document uses several Finite State Machine diagrams to describe the current condition of the Equipment's SECS link,
material handling mechanisms, and process cycle. Each Finite State Machine diagram includes a State Diagram and a
complete description of the states and state transitions.
All Finite State Diagrams have been prepared in the format specified in the GEM standard. This notation is required as a
fundamental part of GEM compliance and must be included in the Equipment SECS Interface Documentation. This
notation is the "Statechart" notation developed by David Harel.
The following are the major characteristics of this notation as it is used in this document:
1. Each state is represented by a rectangle with rounded corners.
2. A collection of sub-states may be grouped into a super-state.
3. The entity described by the diagrams will be in one and only one of the sub-states at all times.
4. Variables representing the current state of an entity do not contain values for super-states, only the lowest sub-
state is represented.
5. State transitions are represented by single-headed arrows.
6. Each state transition is a Collection Event, and it has a unique Collection Event ID (CEID)
7. An arrow directly from a super-state to another state describes a Collection Event that can occur while the entity
is in any one of the sub-states contained in the super-state.
8. An arrow directly into a super-state to the H* (history) symbol describes a transition to the lowest sub-state
which described the entity just before the transition out of the super-state.
