CAN/SERCOS/Ethercat - digital solutions?

CNC Zone reference ethercat, EMC2 and I/O

There is a possibility
A german Company has build a gpl library for doing an EtherCat master on linux and there are example files on how to read EtherCat io pins from a Beckhoff system int hal. All you need is a pc with a supported network card (some intel and rtl ones)
Look at www.etherlab.org
I will be exporing this further.

I open again this discussion for a fresh notice from these link:

osdal-sercos-2009

Then I find these nice videos for makinekit.. but I think is quieùte simple to implement it on linuxcnc ...

linuxcnc-sercos3

in these mounth I search for new fully open sources fiesld bus ...

possible candidates: cc-link ie, powerlink-ie, ethercat (obviusly just tested) and now finally sercos III.

The ethercat is not fully open but quite open ... sercos3 now it seems fully open. Note sercos3 and ethercat have similar max response-time. powerlink-ie is fully open but unfortunately with poor commercial success .... cc-link ie seems the best one for capacity of transmission ... but it is not so open sources as it would be like to present it.

All these field bus is have deterministic capacity. CC-link ie & powerlink ie not require special hardware at all, sercos3 and ethercat require special chip on slave side.
I need to know better if sercos3 with this new dress completely opensources has by chance abandoned the special slave side chip ....

There is no free lunch: without special hardware your latency will deteriorate.

As www.sercos.org/certification shows, Sercos expects you to certify any new developed Sercos device.

Maybe the Mesa Smart-Serial interface will grow into a standard? It is already used by more than just Mesa hardware, STMBL uses it too.
