Help needed to get my 7i76E + 7i85S + 7i73 on my mill going.

loadrt hm2_eth board_ip="10.10.10.10" config="firmware=hm2/7i76/7i76e.BIT num_encoders=1 num_pwmgens=0 num_stepgens=5 sserial_port_0=21xxxx"

I see it now when one learns where to look

If you are running version 16 firmware CR1 indicates a watchdog timeout = latency issue
If you are not running version16 firmware, CR1 is not meaningful unless CR1 and CR2 are both on
(in which case you could not communicate with the card)

To determine the firmware version, you can run mesaflash

mesaflash --device 7i76e --addr 10.10.10.10 --verbose


How are you checking the output?
Note that the field I/O section is completely isolated from the logic section so you
must measure outputs relative to the field common connection

Mesaflash does not exist !

Managed to get out on the web and got install done.

bengt@combimill:~$ mesaflash --device 7i76e --addr 10.10.10.10 --verbose

Output just do not switch to gnd but halshow let us know that output 15 is TRUE

Board failure?

Outputs are not expected to switch to ground, they are sourcing outputs

OK thanks for correcting me. I have read wrong in manual and mixed inputs/outputs.

This is the famous language barrier and understanding other language. So back to the drawing board and do all rewiring.

Done schematics ready for rewiring job tomorrow. Only 1 MURR relay to be polarity changed in safety relay package.

All outgoing control wires other ends have to be investigated if polarity change has to done and all + to relays to be changed to GND.


So hopefully all is well when done tomorrow.

So there is nothing to be concerned about with CR1 as it is version15 on my board, right?
