yes, thank you, I can understand the argument well.
I assumed that the error messages were due to the fact that I did not provide complete information in the PNCconfig file that I created.
We would be happy to tackle the topic first ;o)
Your recommendation to do the latency test, but I don't know how, other than the option that LinuxCNC provides in the menu.
Is your recommendation a command line for the terminal? I'd be happy to try it out tomorrow when I'm back in front of the machine

good morning Thommy,
Is the latency test what you wanted to see?
how do I create a system report with LinuxCNC/Debian 12 bookworm where the network card is listed?
With right click on the Network Icon i see only adresses, not a Network Manufacturer. What you like to see?
I normally work with Linux Mint, so I would like know how...

Looks ok so far, but use this to test and leave it on for at least an hour while doing other things on the PC:
latency-histogram --nobase --sbinsize 1000 --show
As for network, again in a terminal:
sudo chrt 99 ping -i .001 -q 10.10.10.10
leave it for 5 to 10 minutes, then press CTRL+C
post the results.
latency-histogram --nobase --sbinsize 1000 --show
As for network, again in a terminal:
sudo chrt 99 ping -i .001 -q 10.10.10.10
leave it for 5 to 10 minutes, then press CTRL+C
post the results.

That 13 ms ping delay is really bad
Do you have all power management options disabled in the BIOS?
(turbo modes EIST, Cstates >C1 etc)

Hello PCW,
I'm not too familiar with BIOS technical terms.
I can't find points in BIOS like you write. I took a few photos.
In the advanced area I find the "APM Configuration", which has 6 AC power entries. 5 are switched off and the "ErP Ready" is switched on".
Maybe more ideas where I can look?
A question of understanding:
To what extent are the topics you mentioned important for the function and/or security?
I would like to learn to understand the connections. If it can be easily explained, then gladly?
I have also heard several statements about connection speeds between CNC and PC.
The statement was like this - with MESA cards with FPGA chips, the jitter value doesn't play any role, or doesn't play such a big role.
I understand that errors need to be corrected (and I would be very grateful if I receive support from you), but as mentioned, I would also like to learn about the relationships between cause and effect?
Thank you in advance.

I would look through _all_ the sections on the last BIOS page you showed
(AMD CBS for example concerns clocking and network settings could include power management)
Mesa Ethernet cards are not very picky about latency as long as the once per MS servo
thread can run reliably, but your PC seems to have gone to sleep for 13 ms during operation
and this means that 13 successive servo thread invocations have been dropped. Latency
this bad usually involved power management and or CPU clock speed switching which is
why it must be disabled in the BIOS

OK, thank you very much for the explanations.
I have to ask and mention something else here. Is it important for the function of the fully configured machine that the electrical cabinet with the Mesa 7i92 and 7i76 remains powered? If so, is it also important that the PC remains switched on at all times? The question is because, as I mentioned earlier in the thread, I had problems with the network connection after starting the PC from standby. On the one hand, the internet connection of the PC is guaranteed via a small USB hub, but the accessibility of the 7i92 card directly from the PC with an Ethernet cable with ping 10.10.10.10 is not always guaranteed, but with 10.10.10.11 it is. I just checked all the network connection details. Once set up, I imitate it forum.linuxcnc.org/27-driver-boards/3559...ethernet-mesa-boards I notice that the gateway 10.10.10.1 in the mask is always empty when I check. Before, for example, it was Impossible to ping the card with ping 10.10.10.10, but with 10.10.10.11 it is possible. I also couldn't read the card.
Now after restarting the PC (I checked the settings in the BIOS) I tried the same thing again and with 10.10.10.10 and 10.10.10.11 I can ping the card. I can also now read them, which was not possible before. I'm a little disillusioned?
Is this thing going to work? I looked at your suggested menu item AMD CBS, I can select it but I can't turn anything on or off in any way. Such a menu item doesn't really make sense to me.
I'll try out other settings in the BIOS
For me the configuration PC > 7i92/7i76 seems to make a rather unstable impression. I would like to know whether the connected components on the 7i76 can be read or whether the function can be addressed. I hope that we find the way.
thank you very much
