- `dump_odd.py`, dump all data that doesn't have the default value
- `live_monitor.rb`, Allows you to scan, at a regular time, all Modbus registries of a device.
- `mocli.py`, A Command Line Interface for pymodbus
- `read_all_holding_registers.py`, used to scan and get values from holding registers on a TCP Modbus Slave;
- `write_all_holding_registers.py`, used to write a specific value to one or multiple holding registers of a TCP Modbus Slave;
- `read_register.py`, used to get values from various types of addresses on a TCP Modbus Slave (Holding Register, Discrete Input, Input Register)

# PyModMon
Python Modbus Monitor

This is a Python skript that acts as a Modbus slave.
It can be used e.g. for reading data from newer solar inverters made by SMA.

It has the ability to monitor several modbus addresses with a configurable interval and can also write the received data to a csv file.

The logged data can then be used with other programs for analysing or plotting.

Dependencies:
* Python 2.7
* Python package docopt
* Python package pymodbus (and dependencies)

pymodmon_3.py is the updated version for Python 3 (tested with Python 3.7). No additional functionality was added.
