Modbus challenge

I’m trying to tie a modbus PLC into HA for monitoring inside a brewery. We’re using a Solo SL-4848. I need to be able to reset the SV (set point) if needed. According the the docs, the SV register decimal address is 44098.

But the modbus service appear to only accept 0-255) for the address. I admit I’m a complete modbus n00b.

Here’s tje base config. My testing is with the Dev tools at this point.

  - name: hub3
    type: serial
    baudrate: 9600
    bytesize: 7
    method: ascii
    parity: E
    port: /dev/ttyUSB3
    stopbits: 1
