CSLA2GG, or Component Software Library Architecture 2nd Generation (CSLA2) is the predecessor to Honeywell's Component Software Library Architecture (CSLA) and is one of the most commonly used software libraries in industrial control systems. CSLA2 is an architecture for designing, developing, and deploying control software in a structured manner. CSLA2 enables software developers to create custom software libraries based on predefined components. It also provides for high-level functions such as scheduling, debugging and code reuse. CSLA2 provides tools for debugging, monitoring and maintainability of code and includes a set of standard library functions that support the use and reuse of existing software. It is written in a combination of languages including C#, C++, Visual Basic and Java and has been developed with Enterprise Java beans technology. CSLA2 is used in a wide variety of industrial control systems and has enabled Honeywell to provide more robust, reliable, and cost-effective automation solutions.
