The design cycle for proprietary systems can be 3-6 years. By the time of introduction and given a 3-6 year product life cycle, your CPU can be 8-10 years old when you buy it new. Plus, it is not easily “upgradable”
Computer technology moves quickly so PC's are designed to be very upgradable!
To design a proprietary system, designers must design the operating system, backplane communications, network system… and then concentrate on the programming tools.
Open systems use the technology from Microsoft… the operating system is done, the network is done, we need only concentrate on providing the best programming tools in the market

12. P C based control Preserves your investment in Software Development
Proprietary systems are rarely upward compatible. To move to the next platform, you normally must rewrite your program
OPEN systems are upwardly compatible.

13. Better and Faster Networks
Proprietary systems
Limited network speeds 19kbaud - 2MB
Difficult to configure & use
Cost >R10,000
Ethernet is 10MB
100MB is here today
The technology is known, components are INEXPENSIVE

14. Faster & Easier Communications
Open systems
have standard tools application. (OPC/DCOM/ActiveX)
Driver development on standard protocols (IPX & TCP/IP)

15. PC-based Control is not just another Controller
It offers many control alternatives..
PC-Based provides built-in IT connectivity
PC-Based leverages high-volume PC technology to lower costs
PC-Based enables alternative programming methods (e.g. flowchart, C++, VB)
PC-Based has lots of power (e.g. Pentium IV)
THIS SLIDE OUTLINES THE CASE FOR PC-BASED CONTROL AS THE PREFERRED SOLUTION
There are many controls solutions to choose from, many based on proprietary architectures, hardware and software
Choosing PC-based ensures IT connectivity through standard interfaces and allows for the integration of common PC-based databases
Intel and Microsoft spend more on R&D than most controls companies generate in revenue
The data processing and graphics power inherent in PCs allows for more intuitive programming that can be easily understood and modified, even by non-experts
For some time now PC-based control has been able to handle the higher end system requirements with off-the-shelf PCs and Windows NT
