nothing missed ... only not know the STMBL project .... it seems quite simple obtain a calculated angle of joint for send the data to my program for 18 point delta calibration, so I find these project real interesting. Apart from that, I'm investigating the possibility of having open industrial buses with high transmission capacity, to connect multiple Lcnc machines together but also other industrial devices. OpenPowerlink & openSafety seems quite good (not test in these time openlink realtime application ... nex week I think) ... but I'll be happy to try other ways. In addition to all the info I'm getting useful.
Thank you all. bkt 2017-06-01 1:44 GMT+02:00 Chris Albertson <[email protected]>: > > But the goal is to find the best industrial bus for communication > > between devices and open source ... openpowerlink seems quite open, > > master and slave side > > (ethercat for example in > > > I must have missed some of the requirements.
