The OPC Data Access (DA) Server Source Toolkit for Windows provides complete C++ source for Data Access servers. The provided sample servers and sample clients, together with the detailed documentation and online help provides essential information about OPC, OLE and (D)COM.
The server supports all mandatory and optional OPC DA 1.0a / DA 2.05a interfaces and all mandatory OPC DA 3.00 interfaces. The code is modular, highly optimized, efficient and guaranties full OPC and (D)COM compatibility.
The server class structure clearly separates the application specific part from the generic OPC server code. With the included Visual C++ Wizard a server can be developed within a few days without the need to work through the OPC specification. Only a few methods need to be adapted to implement a new server. The code that needs to be modified is clearly separated from the generic OPC code, making updates to new OPC standard versions easy and straightforward.
The availability of the full source code protects your investments and allows you to fully adapt it to your requirements. Whether you want to quickly implement a simple server or create high performance OPC servers with ten thousands of items the OPC DA Server Source Toolkit is the right choice.
The OPC DA Server Source Toolkit offers unique features for performance and functionality improvements of the developed OPC Server like Event Driven Mode for Device Access; Dynamic address space with items added when they are first accessed by a client; Item browsing can be implemented to browse the cache or the device/database.
The included client executables can be used to test a server implementation and therefore eliminate the effort to create own test clients.
Should your server in the future get more complex and require support of Alarms&Events then you can easily enhance it with the OPC AE Server Source Toolkit.
