7i92 not pinging

I am using 7i92+7i76+7i84.

I had connected the system earlier and it was working perfect.

Now I upgraded to LinuxCNC 2.9.2 and added 7i78. But there is no ping. Note: I have added one wifi router as well. Can it cause any problem?

(7i92 set to 10.10.10.10, W5 down, W6 UP)

What is going wrong?

well, I did the network setup as per tommylight post dated 27/11/2018. Many thanks.

now, it is pinging and in the terminal I get,

===================================================

But the gmoccapy configuration is not working. Axes buttons are showing in joint numbers (numeric), motors not moving, showing following errors. HAL and INI file attached.

It is Linuxcnc 2.9.2.

Please guide.




 

I suspect there is a latency issue.

What are the CPU type and clock speed?

and what do

halcmd show param *.tmax

and

halcmd show pin hm2_7i92.0.packet-error-total

The latency,  tmax and packet error data attached in photos.

the error in PNCconfig and "error finishing read! iter=  " is attached.

"cpu MHz        : 800.011"

Sounds like the BIOS has power management enabled so the CPU is running at 1/4 normal speed
You should make sure all power management (EIST, C states > C1, Turbo modes etc) are disabled
in the BIOS.

You can see that there were 14 (0xE) packets timed out so assuming you have the servo thread set for 1000000 ns
(1 ms) that means 14 read requests took longer than 0.8 ms to complete.

Also the halcmd result would be better than the screen shot as it would show all tmax values

Here are some general instructions for fixing network latency issues (from another thread):

This is most likely a latency issue

1. have you run a latency test?

I would suggest "latency-histogram --nobase --sbinsize 1000"

2. Have you disabled all power management options in the BIOS setup?
This include turbo modes, EIST, Cstates > C1, Cool&Quiet etc, basically
anything that causes the CPU to change speeds dynamically or sleep.

3. Also in the BIOS you should disable hyperthreading and any management
engine  related  options that affect the network (like AMT)

4. If your PC has an Intel Ethernet chip make sure you disable IRQ coalescing
(man hm2_eth)

5. Pinging the 7I92 will give you some idea of network latency
(this example assumes the 7I92 is set for a 10.10.10.10 IP address)

ping -i .2 -c 4 10.10.10.10
sudo chrt 99 ping -i .001 -q 10.10.10.10
 (let the last command run for a few minutes and
then stop it with a control C, it will print timing statistics)

If  BIOS changes and disabling IRQ coalescing do not help, the next step is to try
changing the kernel command line options, using isolcpus to isolate one processor
for real time use and pinning the Ethernet IRQ to that processor.
