• Web gateway• Extensions to FactoryLink (XYplot, Mathwork)
F.Momal / LHC-IAS-FS
What worked well
• General stability
• Easy to install
• Easy and fast applications development
• Easy to maintain
• Easy to extend
• Product evolved according to the market
• Bugs were generally solved in the following release
F.Momal / LHC-IAS-FS
Problems• Instability with the X Windows sessions.
• Impossibility to have a session at home.
• Some hardware failures.
• Hard to write reusable code.
• Backward compatibility was not perfect.
• Difficulties to debug network problems.
• Difficult to use built-in database connection

Why changing ?
• Europeans systems were now existing.
• Market trend seemed to be drifting towards Windows NT.
• Windows NT stability OK.
• PCs are powerful enough.
• Windows based standard appearing (OPC).
• Cost
F.Momal / LHC-IAS-FS
Windows advantages• Cheaper: hardware, software and
maintenance
• People are used to the system
• Large amount of programs to add functionality– compilers– drawing programs– math tools
• Interoperability standards
F.Momal / LHC-IAS-FS
Market Survey’s Criteria Run under Windows NT. Client-server and modular structure. Implement the mainly used automation protocol. Offer a complete API. Have an object-oriented RTDB. Use a standard computing language as the integrated
programming language. Possible set-up using an external description source. Follow the Microsoft interoperability standards (OLE,
ActiveX and DCOM). Export the archives in a standard format. Be European.
