This is a python wrapper for TwinCATs ADS library. It provides python functions
for communicating with TwinCAT devices. *pyads* uses the C API provided by *TcAdsDll.dll* on Windows *adslib.so* on Linux. The documentation for the ADS API is available on [infosys.beckhoff.com](https://infosys.beckhoff.com/content/1033/tc3_adsdll2/index.html?id=4279787267115190858).

For any questions, particularly around usage, route creation and ads error messages when reading or writing variables, please use [Stack Overflow](https://stackoverflow.com/) tagging the question with `twincat-ads` and state you are using the pyads library.

# Installation

From PyPi:

```bash
pip install pyads
```

From conda-forge:

conda install pyads
```

From source:

```bash
git clone https://github.com/MrLeeh/pyads.git --recursive
cd pyads
python setup.py install
```

## Features

- connect to a remote TwinCAT device like a plc or a PC with TwinCAT
- create routes on Linux devices and on remote plcs
- supports TwinCAT 2 and TwinCAT 3
- read and write values by name or address
- read and write DUTs (structures) from the plc
- notification callbacks

## Basic usage

```python
import pyads

# connect to plc and open connection
plc = pyads.Connection('127.0.0.1.1.1', pyads.PORT_TC3PLC1)
plc.open()

# read int value by name
i = plc.read_by_name("GVL.int_val")

# write int value by name
plc.write_by_name("GVL.int_val", i)

# close connection
plc.close()
```
