got one ...

thanks

I wanted to say that there is a new Modbus interface: hm2-modbus
available for all Mesa cards, and that fixes a lot of the issues with mesa-modbus.
hm2-modbus needs the latest snapshot of 2.9.4 or master. and may require
a firmware upgrade to at least V2 PktUART.

It adds the ability to have multiple devices on the same RS-485 interface,
device initialization/setup code that only runs once, plus many bug fixes.
Its been running a 25IOC32_PNP for a more than a week now with 0 issues.

The configuration file has a different format (XML) than mesa-modbus.
This format is documented in the mesambccc man page ( mesambccc is
the hm2-modbus configuration file compiler)
 

Happy to provide any info when I get up and running. I'll post the sys specs and latency tests when I can.

Cool. M710q works fine. Have one in a router installed. Can give you the grub infos for the first test.

Just for information. Have also a M2 to realtek nic installed in the m710q which runs stable 2 kHz servo thread. But that isnt necessary. The internal intel nic runs 1 kHz with ease.

Hi guys
I want to connect two MPGs to the encoder inputs of the 7i73
My MPG has A+A-B+B- OV5V e and use two analogue inputs.
To do this, I'll have to use mode 1 on the 7i73 board
Has anyone configured this board in encoder+analogue mode?
Thanks

Thanks, you put my mind at ease. I ordered a refurbished ThinkCentre M710q last night and got the MESA card ordered. Now I have a table to build while I wait for the hardware.

I use M codes for this kind of stuff also. For example M130.

github.com/hausen8/EasyProbe/blob/v2.0/nc_files/M130

Use with:
M130 P255

I am not sure right know, but I had something in mind while writing  "&".
Also some sleeps are always a good idea. Sometimes it gets lost otherwise.

Best regards

Did you finish the machine yet?

As Darth Vader once said: welcome to the dark side!

My test bench
I know it's nothing to you experts, but for me it's a big step.

hi guys i managed to get the communication between Rp1 7i97t+7i744+7i84+7i73 working
Thank you for your help.

I would really like to, but I have to wait a little bit with the next invest in my hobby.

Thank you so much for your hints and ideas!
Yes the optidrive should stay in my setup - at least for the next months. The switch to ethercat, the new servos aso was hard enough to afford. As you mentioned before usb to rs485 is an option, I will go that way until I will be able to spend the next bucks for an ethercat VFD.

Gotch ya. How do I add the key? When I try to save it to trusted.gpg.d it says I do not have the proper permissions

I've passed this on.

Thanks for reporting.
