Ther is no 2.10, where can i find it and i download the 2.9 now, and same problem help please

2.10 or 2.9 will work but you need a recent build.
(newer than 1 month ago)


 

Seems you would need 2.10 for it to work, see
buildbot.linuxcnc.org
but first try this
buildbot.linuxcnc.org/dists/buster/maste...fd6a133f8b_amd64.deb
download and install with gdebi

I try man hm2_modbus, command not found as you see in attachment i have linuxcnc 2.9.4, i check in linuxcnc official site this is the last version, i dont know where is the problem 

I try man hm2_modbus
and man mesambccc
not exist in my linuxcnc i have the last version 2.9.4 i see in linuxcnc official site this is the last version, if there is newest version tell me please
 

The OP may need to update LinuxCNC to the latest 2.9.4 or 2.10

I'm not an expert in this as I usually use a built from source RIP installation

You forgot "man"

I use mesambccc --help, it dos not exist

hm2_modbus is an alternate modbus interface to Mesa FPGA cards with 
PKTUART firmware. It supports additional features such as multiple devices
per interface, one time initialization code etc etc.

You need to have the latest LinuxCNC to have hm2_modbus

if

man hm2_modbus

Gives you a manual page, you have a late enough version of LinuxCNC
to use hm2_modbus.

hm2_modbus will work with your existing firmware.

 

I dont understand what is hm2_modbus new firmware ?
How to use it, what i should do ?
in mesa modbus i just find this
PktUART
MB2HAL
vfdmod
Classic Ladder
i want to use Classic ladder but i dont know how

The original modbus driver only supports one device per interface
(its basically for VFD spindles or just single devices)

For multiple devices, use hm2_modbus

man hm2_modbus

man mesambccc
 

At the end those two adresses are not readable and i change them according the the mitsubishi datasheet with two other adresses and it works thank you so much for your help
i have one last question please now i want to read data from different slaves (3 servo dirvers) how can i do that , i've tried to add a second device initialization on the hal file and i created a new comp file but the problem is one of them connect and the second slave doesn't respond

Are holding registers at 0003 and 0004 readable?

Hello Bro's;
I m trying to control (read/write ) data from MR-JE mistubishi servo drive using the 7I76EU mesa board, using PKTUART, i could reveive data from mitsubishi HMI but when i tried reading the data from the servo drive, it seems like the connection happened but there is not data reed and when i run the linuxcnc it take time to open not like usual time and two type of error appear as shown on the pic bellow. you will find also the .HAL configuration file and the C file where i put the adresse i wanted to read
