EtherCAT Master for QNX Neutrino RTOS v.6.4 or 6.5
STEINHOFF is partner from Koenig-PA and offers the KPA-EtherCAT Master for QNX 6.4 for the DACHS product suite, as well as a DACHS EtherCAT function-block library for DACHSview++. For configuration tasks is offered the configuration tool "KPA EtherCAT Studio".
Features of the EtherCAT- Master for QNX 6.4:
Optimizing bus performance of Ethernet based fieldbusses
Frame transmission time vs. frame size
|Frame transmission time vs. frame size for Ethernet
The frame size defines the maximal frequency of the bus cycle. This is the case for Ethernet based fieldbusses like e.g. EtherCAT, PROFINET, POWERLINK a.s.o.
This fact must be noticed for the design of the size of the slave I/O images and poll sequences. Huge I/O images of the fieldbus slaves lead to low bus update cycles.
