I have heard rumors of ethernet based IEEE 1588 support coming. Anyone know anything about this? Heinrich Munz mentioned it at a conference, and there are a few web references around.

so I guess that is a no?

I realize this is only regarding the vxworks software itself, and not the KRC....but it must be coming?

I'm not certain why this would be needed? You can already set up the robot to update the time/date from an NTP server, via Windows. Given the robot's current 12ms time slice, I don't see what purpose high-precision time synchronization would serve.
-
I think its a substitute for not supporting distributed clocks over ethercat(though hopefully that support will come). According to the lecture I saw " it will enable multirobot sync alongside MXa" but that is a paraphrase...
Also I would think this would allow the external plc cycle to sync to the internal cycle....12, 4...whatever it may be(hopefully faster someday).
-
Hm... I had heard that KUKA already has an option package that does something like this, for tightly-syncronized entertainment systems. I think the Harry Potter ride at, um, Universal Orlando? Maybe? I've never seen it myself.
That's probably pretty specialized, though.

I have heard of that (tech package entertainTech !) but don't know much about it. Possibly this distills out some of the core of that. Nothing against roboteam, it works quite well. I just want to sync my external motors as well as possible. One thing I haven't tried in that regard is looking at the IPO position, which apparently leads the setpoints by a pretty large margin(40ms?) . I just don't like having to run rsi in order to get this data. Sorry, that was off topic, obviously time sync isn't going to fix that!
