OpenDAF is a software framework allowing the construction of industrial data acquisition and control applications.
It is built on a scalable modular architecture providing easily extensible functionality. OpenDAF can operate on both embedded and server platforms.
The framework is composed of services and modules organized into stacks. Modules and services are configured into the process address space by a service configurator, leading to application architecture determined during deployment. The framework can be extended by creating new modules and services and by configuring them into the process.
The simplest way of creating new modules is our graphical module creation tool Modulix which is fully integrated with the Eclipse IDE platform.
