H100 communications for speed reference using mb2hal modbus

I am in need of some help. In mb2hal.ini transaction 02, I can not get the set speed working. The crash message states that " mb2hal.spindle-set-speed does not exist ". I have stated it in the custom_postgui.hal file. I am wanting to have the " run speed slider " populate the set speed parameter in the drive.
Transactions 00 and 01 work fine

Any ideas would be appreciated.

I would suggest commenting out the offending line till you can get LinuxCNC to load. Then check what pins mb2hal created. I question whether mb2hal actually creates mb2hal.spindle-set-speed, usually I see pins something like mb2hal.0.1 where the first number is the transaction number and the second is the element number.

Or am I missing something? Is there a method to have mb2hal create labeled pins?

transactions 00 and 01 load and work fine. if you use nelements, pin names are not required. And no, spindle-set-speed is not being created. 00 is spindle-speed and 01 is spindle-at-speed. These are being created, and work fine via axis

So, I got it working, one line in the manual saying set speed is 201h (513d). Totally missed it. And the pyvcp value had to have a F after the label


[TRANSACTION_02]
FIRST_ELEMENT=513
NELEMENTS=1
MB_TX_CODE=fnct_06_write_single_register
MB_RESPONSE_TIMEOUT_MS=500
MB_BYTE_TIMEOUT_MS=500
HAL_TX_NAME=spindle-set-speed
MAX_UPDATE_RATE=0.0
DEBUG=1


## connect the PyVCP run speed slider to mb2hal input pin
net spindle-set-speed mb2hal.spindle-set-speed.01.float <= pyvcp.spindle-set-speed-F
