Development Time Line for Proprietary Controllers Microprocessor Selection/Design First Product Release Operating System Selection/Design I/O and Network Selection/Design Useful Product Life 1 2 3 4 5 6 7 8 9 10 Time in Years

Development Time Line for Proprietary Controllers Open Microprocessor Selection/Design First Product Release Operating System Selection/Design I/O and Network Selection/Design 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 Useful Product Life 1 2 3 4 5 6 7 8 9 10 Time in Years

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.

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

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

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
