Design
your SCADA solution like an airport, not like a fortress!
Have you ever wished
you could design a bullet-proof SCADA solution without worrying
about how many points and users it will be able to serve
eventually or its future enterprise connectivity? personalSCADA™ has
all the flexibility that you need to build that solution
today for
tomorrow.
Figure: Unlike conventional SCADA products, personalSCADA's
enterprise information architecture enables you to
build secure and flexible solutions that can be implemented
rapidly!
Conventional SCADA model
The conventional SCADA model is limited in handling the
needs of enterprise users:
Enterprise Information Management
- Traditionally, SCADA systems were used for supervisory
automation and control functions rather than information
management
- Also, most SCADA systems do not cater to multiple user
types especially non-SCADA, enterprise users
Information security
- Conventional SCADA systems provide perimeter security,
which is susceptible to holes when the SCADA system is
expanded or integrated with other systems
- In addition, SCADA systems generally do not address the
need for high-level of granularity in managing authorization
for multiple types of users
Presentation is often mixed with processing
- This creates challenges when offering different types
of user interfaces to different operational and business
users who need to access the SCADA system
- Most SCADA systems provide rigid user interfaces that
can not be personalized easily to meet different needs
of different user profiles
Configuration is tied to hardware structure
- Often, the first step in configuration is to determine
the hardware infrastructure that hosts the SCADA system,
and then the configuration is tied to the specific infrastructure
structure. Thus, system expansion is always a new project
- Being tied to a specific infrastructure makes it very
difficult or expensive to create standby (failover) configuration
Key Concepts of personalSCADA™
personalSCADA™ is designed to suite the new information
age by eliminating the above mentioned limitations of the
conventional SCADA model.
Designed to manage information
- personalSCADA is built upon Eutech's patented real-time
information management framework. Service Agents are responsible
for managing backend processes whereas Personal Agents
deliver personalized views of the system
- Unlike conventional SCADA systems, information exchange
between SCADA and enterprise-level applications is done
through open databases or XML
Simple user interface that can be personalized
- personalSCADA offers a 'zero code development' environment
with drag-and-drop configuration to allow rapid deployment
as well as personalization by different users
- It is designed to hide backend complexity and allow a
homogeneous working space across multiple subsystems
- User views can be personalized without compromising system
security
Information security
- personalSCADA's information security model is built into
the product architecture
- personalSCADA offers secure remote access through patent
pending 'Catseye™ Agent
for SCADA' for greater security for Internet access
to the SCADA system
- Also, because of CatseyeAgent's application-level authentication,
there is no requirement to 'punch holes' in the security
system to allow 3rd party integration
Project-based expansion
personalSCADA is designed for system integration engineers.
It has multiple ways to expand it functionality to fit complex
project solutions.
- C++ & VB Application Programming Interface (API)
for real-time data access
- Ability to plug-in custom-built drivers
- Ability to plug-in user interface and application components
to expand the functionality
Designed to handle real world SCADA problems
personalSCADA is not 'just another SCADA system'. It is
specially designed to handle hard system integration problems,
especially in complex projects. Among the key capabilities
in this regard are:
- Single central configuration while the backend processing
is distributed among many computers. This means, it is
possible to add processing power dynamically without changing
the configuration
- It allows easy implementation of standby operation (redundancy
and failover strategies)
- It allows implementation of control strategies using
external expert-systems
