Technosoftware AG - Innovative Software Solutions in Automation

The OPC Client Framework C++ for Windows provides a complete C++ application framework which includes class libraries and tools for fast and easy development of OPC Data Access and OPC Alarms&Events clients.

OPC Clients can be developed fast and easily without the need to spend a lot of time learning how to implement OPC Data Access and OPC Alarms&Events. Most of the OPC and (D)COM handling is already done by the client framework.

The client framework API is easy to use and often used functions, e.g. Status Polling, can be delegated to the framework. Even the complex asynchronous subscriptions can be done with just one function call.

The provided sample servers and sample clients, together with the detailed documentation and online help provides all essential information and tools you need to successfully develop your client application.

For a low price you can develop as many products as you want and already support two of the most important OPC specifications; OPC Data Access and OPC Alarms&Events.
