This function is normally done by an addf in your .hal file as one of the last addf's, often next in line after the addf that updates the outputs each servo cycle. That way the watchdog gets petted even if the rest of the system is sitting idle waiting for its slow human to tell it what to do next. :)
For an older 5I25 card install, it looked like this in the .hal file: addf hm2_5i25.0.pet_watchdog servo-thread # else he bites! Do a "sudo dmesg -c" which will clear dmesgs cache, then start lcnc and stop it. send the next "sudo dmesg >filename 2>&1" and post it here as an insert of that filename. I also find that printing a copy for future reference is also quite handy as you go about configuring a working system. Point is, that if the setup has a watchdog, it should show up in that dmesg listing, the whole thing is perhaps 60 lines in one of my machines that uses a 5I25 card. And its now part of the of the output write function now done internal to the card when and output is written by the driver. So it does not show up in my dmesg listing, and that line quoted above now has a #in front of the addf. Check the docs you have on this x200 vfd for any mention of a watchdog. That should define how to "pet" it to keep it from barking. OTOH, I do't have an x200 VFD, and its possible that it does not report its presence when the program is run. In which case see the docs for the x200. > > Danny > > On 6/16/2016 11:04 AM, dan...@austin.rr.com wrote: > > It's modbus, sorry forgot to mention that. > > > > What baffles me is the Spindle buttons on the panel, AFAIK, just map > > to the same spindle-run in the HAL that M3 goes to.
