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.
OSSS-EA’2006
Shortage
a. Compute module should be imported in the SCADA system.
b. Developing the SCADA system based on scientific computation software.

Developing SCADA System based on Scientific Computation Software Scilab
OSSS-EA’2006
To Solve the Shortage of Traditional SCADA
We propose a method
The Design of SCADA System Based on Scilab
1. Costs, Scilab is free.
OSSS-EA’2006
Why choose Scilab? Not Matlab, etc.
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 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.

What we have done?
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.

The Realization of Data Acquisition with Scilab-OPC
OPC interface
With OPC technology, we can acquisition data from different device easily.
And not need to know physical structure.

Acquisition Data
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.

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.
OSSS-EA’2006
Conclusion
SciSCADA system is proposed based on Scilab.
It can …
Enhance the SCADA system’s scientific compute ability
Realizing control and optimization on-line
