Configuration 7i92 and 7i77 - get error

Do you have all power management turned off? (no C states > C1)
idle=poll in the kernel command line helps also (set with grub)

What are you ping times to the 7I92?

I will look for ping today I think, also I will add to ethernet interface settings
"hardware−irq−coalesce−rx−usecs 0" as in the hm2_eth manual
Now I read this manual for some additional help.
Also ethernet cable is very short, less than half of meter. And it also shielded to the ground. Phisicaly, ground is neutraled.

Power management, it disabled complitly in BIOS. I had very big latency delays when I bought this PC, more then 300k. After disabpling a lot of parameters in BIOS I got 30k. And after setting isolcpu=2,3, I got 15k and less.

PCW, I didn't understood, what does it mean "idle=poll", where to set it?

Also, how to disable IPV6, if I have it?

I've check ping to mesa board and I got

rtt min/avg/max/mdev = 0.187/0.287/1.354/0.129 ms

In hal I increased watchdog time to 1300 000 (I thing I don't make here any mistake in zeros).
And it seems, everithing work fine.

Now I start to run servos and I wonder, I've connected them to ENA pins of mesa 7i77 board (it's near analog output). What HAL pin controls this pin? Where it's written in my hal address of this pin?

After turning on I laso received remote error from 7i77 as (27) Over Current.
I don't understand why, I've connected only one relay. I use 7i77D

rtt min/avg/max/mdev = 0.187/0.287/1.354/0.129 ms

1.354 ms is pretty bad...

Now I start to run servos and I wonder, I've connected them to ENA pins of mesa 7i77 board (it's near analog output). What HAL pin controls this pin? Where it's written in my hal address of this pin?

The first 5 analog enables (0 through 4) are controlled by the analogena pin

If you have an overcurrent warning, you may have the relay miswired
(flyback diode backwards?) or too large a relay without a flyback

I have flyback diods, maybe relays are a bit large, I will look.
What current should be on one output of the board?

350 ma is max
Are you sure your flyback diodes point the right way?

On a 7I77D:

+12/+24V to relay_coil-1 + diode cathode (band)
7I77D-Output to relay_coill-2 + diode anode

Yes, for diod connection I'm sure.

Relays are something bigger than I used previously. They are from refitting machine, they need 387mA.
Will they work? I think I need only 6 such relays.

Idle=poll goes before or after the isolcpu in grub.

I want to clearify, I need to write it in the same line as isolcpus, like this
<<<<.... = "isolcpus =2,3 idle=pool " >>>>?
