The
Data Collection Component
The Data Collection Component (DCC) features
comprehensive Statistical Process Control (SPC) analysis
capabilities including all traditional Shewhart and
Attribute charts, along with cusum and Exponentially
Weighted Moving Average (EWMA) control charts. The SPC
capability is offered as part of a data collection
system which accommodates capturing non-SPC context data
such as lot, wafer ID, process step, etc. The DCC
includes configurable, table-driven security services so
that privileged application features such as the
configuration of SPC run rules are password protected.
In the usual
client-server deployment, the DCC server communicates
with User Interface processes, equipment interface
processes, and java-enabled web clients, all using the
DMH message system. The DCC is capable of sending e-mail
messages, or placing telephone calls to notify
recipients when SPC alarms occur. The DCC includes a
Graphical User Interface (GUI) client application that
can be used to manage the configuration of data
collection items, to view charted data, or to view
tabular reports. The GUI also features the ability to
manage SECS Trace Report and Event Report data
collection by communicating with instances of the Hume
SECS/GEM applications. The GUI can be used as a
ready-to-run solution for managing automatically
collected data, or as an embeddable component for the
OEM or System Integrator.

The
Event Processing Component
The Event Processing Component (EPC) brings events and
context data up into a high-level processing framework,
where the table-driven configuration dictates how the
events are to be handled, and what their meaning is as
far as managing state, acquiring performance data, and
executing application logic. The EPC is designed to
serve as a single entity for both event-based business
rule execution, and for finite state machine execution.
The EPC is designed to scale well. It can be applied to
smaller problems such as coordinating the material flow
in a workcell, and to larger problems such as tracking
state-dependent performance data for dozens and dozens
of connected factory tools. In addition to configurable
logging and diagnostic tracing, the EPC features a
delightful new scheme for simplified high-performance
access to persistent data.

The
Scheduling Component
The Scheduling Component is a visual interface for
managing periodic or one-shot tasks. Screen shots and
an overview are viewed using the link. In addition to
serious uses such as periodic report initiation, the
component is handy as a musical alarm clock when
traveling with your laptop computer!
