You should install the pymodbus module on the new version of Python.

Example:

Code:

cd /Users/marianneandersen/opt/anaconda3/lib/python3.9/
cd Scripts (I'm not sure if this is needed)
pip install pymodbus

I have already done that.

“(base) MacBook-Pro:python3.9 marianneandersen$ pip install pymodbus
Requirement already satisfied: pymodbus in ./site-packages (3.2.0)
Requirement already satisfied: setuptools<66.0.0 in ./site-packages (from pymodbus) (63.4.1)
