Do you mean 'modpoll the proper registers' to mean 'read several holding
registers in one operation'?
If so: I had that problem with the Toshiba VFS-11. See the note in my

I haven't considered a generic VFD or Modbus device driver, because not
only do the device functions vary widely, but so do implementations of the
Modbus standard.
Yes, I found that too. I built my code based on the GS2 module and
Michael's code.
Early on, I avoided using the GS2
