I changed the PC addr. to 11, same behave as before, no succ.

please see attchments

Can you check if get any LEDs illuminated on the 7I76E RJ45 connector
with the Ethernet cable unplugged?
 

The PC has the wrong IP address, it should be
10.10.10.11
not
10.0.0.10
After fixing that, check with
ping 10.10.10.10
if the Mesa is set for a static IP of 10.10.10.10 see manual.

no real upstes to the shop for a long time. The machines have their own threads and I am currently moving house.
Starting a new job over a year ago lead to buying a new house with a new shop. So while waiting for the permission to remodel the house, I started on the workshop with a lot of pressure washing and cleaning the floor and filling the old crap way with concrete and seal it





then installing a staircase to rech the 2nd level of the former stables to rech the future workshop of my wife.



next step is to put in new windows and maybe some insulating before I am ready to move the heavy machines.

still figuring out my shop setup, but I have a rough Idea now:



sorry for it being in German, and Wully is the Fehlmann Picomax 100  mill, Ditte the Gildemeister lathe, Jülia is my pickup
space an comfort wise this will be a step up from my current workshop and miles away from my first one in my apartment bedroom 

ok, but i have to look what is available for a good price,
now i have ordered parts for ~14 Euro at aliexpress, ( >= 4 boards)

3.5 Euro / Board + 2 Euro PCB + 18 Euro TangNano9K + 8 Euro 5xBOB + .....

<35 Eruo for 5 or <43 Eruo for 10 axis

sounds too good, but will see

EDIT: ok, forgett the W5500   + 4Euro


 

Changed the network cable, same result.
Led shines green

Dear all,
after trying to update my hardware and the necessary disassemble the project got stuck for years

sorry the edit deleted the rest of my original message.....couldn't retrieve it..

Could be cabling problem but the "ip a" report shows
the link as up,  could also a be a host PC issue, or be a
7I76E issue.

What do the LEDs on the 7I76E RJ45 connector show?

 

From memory the TXS level shifters are not really designed for driving a cable of any length, ie they are more for component to component on the same board.
The fet bus switches I use with pull-up resistors on the high side will easily drive a generic breakout board on the end of a 1.8m Parallel Port cable. TBH I copied this method from the Mesa 7i92 or 7c81 schematics, so I don’t claim any originality just can confirm that it is reliable. The only issue being that a buffer is required to drive any load, but 99% of breakout boards use them anyways.
On the other hand if you want to set 8 pins aside for dedicated inputs that are 5v tolerant via a 3.3v device a 74lvc245 is the part you want.

Oh yes my fault, 10.10.10.10 returns nothing.
So I suppose the mesa is gone.

You would need to

ping 10.10.10.10

To check connectivity to the 7I76E
 

the output from command "ip a" and "ping 10.0.0.10"

TangNano9K + W5500 to 2xBOB-IO

 

W5500
Level-Shifter (TXS0108E)
RGB-LED
Modbus
I2C - 5V (hope this will work via the level-shifter)

Maybe a good and cheap universal-board
