# Pymodbus-REPL

Pymodbus-REPL is a REPL (Read-Eval-Print Loop) tool for working with Modbus devices using the Pymodbus library.

## Development Setup

### Prerequisites

- Python 3.8+
- Poetry (installed globally or within a virtual environment)

### Dev instructions

1. Clone the repository:

   `git clone https://github.com/pymodbus-dev/repl.git`

2. Navigate to the project directory:

    `cd repl`

3. Install dependencies using Poetry: 

    `poetry install`

**NOTE** This repo is meant to be an helper for [pymodbus](https://github.com/pymodbus-dev/pymodbus) and the usage requires
a working version of pymodbus.

The installed `pymodbus` library for local development can also have impact on the path resolution while working locally on this repo.
To overcome that problem, please make sure to run the [client](./pymodbus/client/main.py) and [server](./pymodbus/server/main.py) files
from with in the respective working directories.

For .e.g

#### Run Server
```
(pymodbus3.8)
❯ python3 main.py --host 0.0.0.0 --verbose run --modbus-config default_config.json --modbus-server tcp --modbus-framer socket --modbus-port 5020 --unit-id 1 --unit-id 2 -u 4 -r 1 --timeout 2
2024-02-28 14:38:24,952 INFO  logging:97 Modbus server started

2024-02-28 14:38:24,952 INFO  logging:97 Server listening.
