Ethernet based Real-Time Network for QNX Neutrino RTOS Vers.6.4.x with EtherCAT master and EtherCAT slave controller boards
Steinhoff Automation & Fieldbus System shows at the fair SPS/IPC/DRIVES in Nürnberg, Germany
the base components of a high performance real-time network based on EtherCAT technology.
The EtherCAT master operates as a native LSM module with the ethernet stack of QNX 6.4.
The master is able to drive hundreds of EtherCAT slave boards without decreasing the bus cycle significantly. The shortes bus cycle is in the range of 15-30us with a minimal packet size, the duration of passing of a single slave within the ring topology is round about 40ns.
EtherCAT will also be supported by DACHSview-SDL 1.3 / Q1-2010.

Comments
Since this is an LSM, that means it will work with qnet, is that right?
If so, does the driver support priority queuing/dequeuing? (i.e. does that mean that priority is preserved end-to-end at the application layer?)
