WEB-FAQtory
is the first and only Distributed SCADA System. All
other SCADA applications are essentially standalone,
at best only communicating with a database and require
separate, expensive, licenses to run on different PCs.
WEB-FAQtory,
on the other hand, allows unlimited copies of the equivalent
of other SCADA applications (the WEB-FAQtory
Client) to run on unlimited PCs at unlimited sites/plants.
All communicating with each other and the central Server.
WEB-FAQtory
is designed to use the Internet as its communication
medium and by utilizing the unique WEB-FAQtory
TCP/IP based Network OS, the bandwidth requirements
are at the absolute minimum. Coupled with the WEB-FAQtory
DNS (Domain Name Service) and full buffering for network
failures, allows the components of the WEB-FAQtory
system
to use cheap, readily available dial-up Internet accounts.
No dedicated IP addressees are required.
The WEB-FAQtory
system consists of the following seperate applications:
The Server. The Server receives all data changes
from all Clients and saves them in a RDBMS (SQL Server,
Oracle, MySQL, Access and Foxpro). Each database type
is fully optimized for minimum data size and maximum
flexibility. Full use of Stored Procedures in the SQL
Server and Oracle databases allow for the maximum possible
database utilization (the MySQL database is still faster
then SQL Server/Oracle and is the recommended database
for WEB-FAQtory).
Access and Foxpro are included for maximum compatibility
with existing SCADA installations. Unique WEB-FAQtory
database design allows for unlimited historical trending
of any combination of tags (from any Client), irrespective
of the frequency of individual tag updates. The Server
is also an OPC Server, allowing the display, in an OPC
Client, of all the tags connected to the Server irrespective
of how the tags are connected to the originating Client.
Full display and trending of all tags, grouped by Client.
The Server is also the central security system for connections
by Clients and Monitors with fully configurable groups
for maximum flexibility in user access/privilages. Full
SNMP node for integration with Network Monitoring applications.
A WAP interface to the Server allows the display/update
of any tag from a WAP enabled mobile phone. More
The Client. The Client is the equivalent of a
conventional SCADA/HMI application but vastly more capable
and advanced. The schematics/pages built by the Client
are separate runtime applications and all building/changing
is done in realtime. Unlike all other SCADA applications
where the user has to constantly swap between the development
and runtime environments, the Client is 100% runtime
only. Everything is done in the runtime environment
with just a few clicks of the mouse. This means that
the Client is several orders of magnitude easier to
use then any other SCADA application and no matter what
changes are being made to the Client it is always communicating
with the Server and the other Clients. No need to stop
the plant to change the schematic. As all schematics
are separate runtime applications, they are always live
and saving data/checking for alarms irrespective of
their being displayed or not. Each Client can connect
to unlimited tags either via OPC,DDE or one of the several
hundred included WEB-FAQtory
drivers. Unlike all other SCADA applications, there
is no tag limitation to WEB-FAQtory
and unlimited PCs running unlimited copies of the Client
can connect to the Server with no additional license
requirements. More
The Monitor. The Monitor is basically a remote copy
of the Client with exactly the same facilities (apart
from making changes to the schematic). Unlimited Monitors
can connect to a single Client. The WEB Monitor is the
Monitor running in a Web Browser and for the first time
for any application (SCADA or otherwise), allows for
pixel perfect display of the original schematic with
the full facilities of the Monitor. More
In addition to the above, WEB-FAQtory
includes a full SDK (Software Development Kit), for
the building of user defined applications based on the
WEB-FAQtory
suite. The SDK consists of a DLL for building ASP pages
and several ActiveX controls for advanced standalone
applications using virtually any development environment
(VB, Delphi, VC++, Access, VFP, etc.). |
