ibaNet (FO)
Different ibaNet communication protocols were also developed with the different generations of the ibaFOB boards. The cards of the ibaFOB-D series support all previously realized protocols, guaranteeing a complete downward compatibility.
The following table shows an overview of the available protocols with an indication of transmission speeds, signal number, data acquisition times (sampling time) and typical devices:

ibaNet-E
ibaNet-E is the protocol of the interface with the same name.
ibaNet-E enables fast, efficient and deterministic communication between the acquisition computer and other involved components. Standard Ethernet cabling and standard network infrastructure can be used for data communication. This supports the usage in a virtualized environment, as no special boards in the ibaPDA computer are needed for connecting appropriate peripheral I/O-devices (e. g. ibaW-750).
With ibaNet-E, different applications, i.e. data acquisition from several data sources as well as controlling through outputs, can be realized. Not every ibaNet-E device supports the full ibaNet-E scope of functions. Therefore, some functionalities may not be available for all ibaNet-E devices.
