Introduction to SCADA - Shortage and Solving
Methods

• Only implement the functions of data acquisition
  and data monitor, having no enough scientific
  computation ability to do complicated control and
  optimization.

Shortage

• Compute module should be imported in the SCADA
  system.
• Developing the SCADA system based on scientific
  computation software.

The Design of SCADA System Based on Scilab
To Solve the Shortage of Traditional SCADA
We propose a method

• Developing SCADA System based on Scientific
  Computation Software Scilab

OSSS-EA2006

The Design of SCADA System Based on Scilab
Why choose Scilab? Not Matlab, etc.

• 1. Costs, Scilab is free.

2. Source, Scilab open its Code source, which
allow us modify the software according to our
opinion, or integrate Scilab to our own software.
3.Toolbox, Scilab provides much toolbox in
control and optimization area.

• 4. OS, Scilab support Linux operating system.

The Realization of Data Acquisition with Scilab
The Key Technology
Realizing exchange data between factory and Scilab
What Should Do?
Developing Scilab Interface with Factory Device
According to Some Industrial Protocol, Such as
OPC, Field Bus, Industrial Ethernet, etc.
OSSS-EA2006
17
The Realization of Data Acquisition with Scilab
What we have done?

• OPC interface
• Modbus-ASCII interface
• Industrial Ethernet (Modbus-TCP)

OSSS-EA2006

The Realization of Data Acquisition with
Scilab-OPC
OPC interface
The OPC Foundation has established a set of
standard OLE/COM interface protocols intended to
foster greater interoperability between
automation/control applications, field
systems/devices, and business/office applications
in the process control industry.

19
The Realization of Data Acquisition with
Scilab-OPC
What can OPC give us?
With OPC technology, we can acquisition data from
different device easily. And not need to know
physical structure.
OSSS-EA2006
20
The Realization of Data Acquisition with
Scilab-OPC
Developing OPC Interface
Through writing OPC DLL to extend Scilab OPC
function.
OSSS-EA2006
21
The Realization of Data Acquisition with
Scilab-OPC
With SciSCADA toolbox, we can easily acquisition
data from OPC server.
Acquisition Data

22
The Realization of Data Acquisition with Scilab
We also developed Modbus Protocol Interface, and
Industrial Ethernet Protocol Interface. They can
let Scilab acquisitive data easily from device
through Serial Port and Ethernet. Also, to
storage the data to database, we developed Mysql
interface.

23
The Realization of Data Acquisition with
Scilab-Modbus
With SciSCADA toolbox, we can easily exchange
data with Modbus device.

Applications in a Water Enterprise
Water Supply Enterprise ask us to acquisitive
data from device and storage data according to
their need. Also advanced control should
included in the project.
Problem

With SciSCADA Toolbox, we can easily acquisitive
data from device, and Scilabs compute ability
enable us realizing advanced control.

Conclusion

• In the past, Scilab only can used in discrete
  and off-line control in laboratory. Through the
  SciSCADA toolbox, Scilab can exchange data with
  device layer and Ethernet layer convenience. It
  transforms Scilab from discrete and off-line
  control to continuous and on-line control.

Conclusion

• SciSCADA system is proposed based on Scilab.
• It can
• Enhance the SCADA systems scientific compute
  ability
• Realizing control and optimization on-line
