Network Bus

All data exchange between applications of the data acquisition, machine control and processing is done via the network as bus system.

Participating processes write to respectively read from network. The data can be transported over different media depending on the application.

Data is always written by one process, and can be read by any process.

Different transport mechanisms are implemented. Standard transport via network is available with the network protocols IP and UDP multicast. Time-critical transport is granted by a separate ethernet-based network with a proprietary protocol.

Data objects to transport via the network bus contain its own serialization and deserialization methods to convert the data into byte-stream and to extract data from byte-streams.

All information about the data transport can be configured flexible by data base entries. The network serves as interface between data acquisition, machine control and end users.
