## Modbus TCP
After the hardware setup, there are many ways to test the modbus communication. QModMaster is a great tool for exploring Registers via a GUI - https://github.com/zhanglongqi/qModMaster. You could also write some short script in Python using the module pyModbusTCP (https://pypi.org/project/pyModbusTCP/), see **** in this repo for an example.
