PROFINET

Realtime Performance for Realtime-Communication!

 

DACHS-PROFINET

 

 

PROFINET is a very fast Ethernet based Fieldbus with bus topology.

 

QNX 6.x support for DACHS PROFINET is offered.

 Please, contact us for further information

 


DACHSview based applications and visualizations are also supporting DACHS PROFINET.

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.
