hm2_modbus, mesa modbus, vfd modbus, mesambccc - example configs/intro?

Hi all,
I'm working on a machine with 7i96s for brains and a 7i75 for IO. I'm adding a fuling BD612 VFD so i can use the high rpms that the spindle is capable of, and I'd like to do this via modbus.

I'm aware of the hm2_modbus and mesambccc manpages as well as the docs page Mesa Modbus, but... I can't tell if they are referring to the same thing. It seems clear that vfd_modbus and mb2hal are different ways to do this.
I'd be grateful if someone could confirm that these refer to the same thing or different things...

It's clear that hm2_modbus and mesambccc are parts of the same system - does anyone have an example file(s) for setting these up? I'm happy to spend hours with the manpages and guide but get on far better reading and tweaking existing code, than trying to write it myself from scratch.

I've flashed the 7i96s_pktv3.bin bitfile successfully, not sure of next steps. 

Many thanks,
Andy

 

I don't have access to it today but I have an example GS10 VFD configuration for hm2_modbus
that I can post tomorrow.

It's been running on a test config for several months 24/7 without any issues.
 

Thanks Peter,
Can you shed any light on whether the Mesa Modbus page ( linuxcnc.org/docs/stable/html/drivers/mesa_modbus.html ) relates to hm2_modbus?

No that references Mesa Modbus and several userland modbus interfaces
that use kernel serial port/USB serial port drivers.

Sample hm2_modbus config for GS10 VFD including 7I96S hal/ini files:

 

I have found its easiest to put the mbcc files in the ~/linuxcnc/configs directory
as that seems to be in the default search path for the binary (xxxx.mbccb)
