Network Modules
SPC data collection over a local area network is simplified using our
DataLyzer® Spectrum Network modules.
The DataLyzer® Spectrum-SPC Stand-Alone software is used to
create files and print reports for the larger network system. Hub and
Satellite modules are added to allow system-wide monitoring and remote,
real-time data collection.
The Hub Module allows hundreds of processes to be monitored from a
single location. Satellite stations provide simplified data entry.
Operators with little computer experience quickly grasp the use of this
system, minimizing the need for training.

Server
IT Area: Network Server
The main DataLyzer® database resides on the
server (software versions are available for Access, SQL and
Oracle.) The hub or satellites connect to the central server to
access the DataLyzer® system database for system-wide monitoring
and data entry.

DataLyzer® Adminstrative Hub
Quality Area: Administrative Level
Stephen’s unique network scenario starts by
adding an Administrative HUB module to the Standalone package.
Using the Standalone’s analytical power as a foundation, the HUB
adds two primary capabilities:
1) The ability to assign charts to specific stations for data
collection on the plant floor.
2) The HUB also automatically monitors status of these charts
through a unique, color-coded status screen refreshed at
user-defined intervals. One HUB Administrative station can
monitor hundreds or control charts assigned to scores of
satellite computers throughout your facility*. The HUB status
screen is organized by satellite to indicate the locations where
charts are assigned.
Processes are represented on the Hub’s Status screen by
color-coded blocks. Color-coding reflects various statistical
control conditions and beyond that whether data is being
collected and when. These colored blocks are organized in rows
corresponding to the “Satellite” station where they have been
assigned on the network by the administrator. The HUB’s color
coded status screen is interactive allowing administrative users
to click any process block to instantly display the latest
control chart, histogram or summary statistics from the shop
floor or QC labs. The HUB administrator can edit a satellite’s
data, display process notes or print any one of numerous
reports.
Beyond that, the administrative HUB offers various preference
settings for its operation and permissions for the satellite.
The HUB’s preferences primarily define how its status screen
will appear and function. Additional permissions offered by the
HUB include to each satellite include: data editing, delete
data, add or edit process notes, stop and start process control
limits, print reports, change language of operation, enable or
disable automatic email alerts and requests to supervision.
Specific Hub reports: Data collection report (when and how much
data was collected by station and operator),
characteristic/sequence summary reports.

Executive Monitor
Quality Area: Supervisory Level
The Executive Monitor is often used by
upper management or supervisory personnel who need instant
system-wide status information and report printing priveleges
without the responsibility of system-wide setup and
administration. Executive monitors operate like read-only Hubs.
They display the same system-wide status screen like the Hub and
offers precise, comprehensive analysis, corrective action notes
review and printing for any one of 36 system reports. However,
the Executive Monitor has no administrative capabilities and
cannot reassign charts for remote data collection. These tasks
are performed by the administrative Hub. As an alternative the
Executive monitor can be setup to access only a departmental
subset of the HUB’s status so that individual department
supervisors can view the status for their specific area.
Executive Monitor and Satellite packages are the same price,
making them commercially interchangeable. There are virtually no
limits on the number of Execs which can be supported by the
DataLyzer® system+ (other than specific database
platform restrictions).

Data Entry Satellite
Quality Area: Data Entry Level
Satellites are used by production operators
and lab personnel whose responsibilities include data collection
and process adjustment. Satellites can be implemented wherever
data will be entered. Multiple, inexpensive Satellite packages
can be used+ for remote, real-time data entry and
basic analysis. Data entry is accomplished using graphical
control charts like X & R and P charts or Histogram. Tabular
(by-part) formats are also supported. Operators are encouraged
to enter notes for problem processes. Each Satellite maintains a
summary of its characteristics, organized by sequence. This
local status screen provides an overview of the station in terms
of 20 statistical and process control conditions. Satellite
users enter data instantly by accessing any displayed collection
sequence.
Reliance on the HUB
Charts are created at the Hub and assigned to the Satellites
through the network, so minimal database system access is
available to the satellite. Key statistics are user selectable
on reports and displays and recalculate each time data is
entered. Reporting is available by permission at the satellite
and direct interfacing is included for most RS-232 and USB
gaging systems. “Local backup” can be used in SQL Server® and
Oracle® systems to continue using local Satellites during
network or database failure. |
+MS Access systems should not exceed 10 stations. MS SQL and
Oracle systems are virtually unlimited.
