![PyPI - License](https://img.shields.io/pypi/l/pytunelogix)

Windows Exe (no install required) -> https://github.com/Destination2Unknown/pytunelogix/releases

To install use:

```
pip install pytunelogix
```

PID tuning in 4 Steps:
```
A-> Record PRC using Logger
B-> Tune using PID Tuner
C-> Refine tune using PID Simulator
D-> Test tune with FOPDT Simulator for Logix PLC
```

To use, create a launch file:

```
examplelaunch.pyw #use pyw for no console
```

**PID Logger**

To launch, use:
```
from pytunelogix.pidlogger import clxlogger

clxlogger.main()
    
```

**Stage 1 - PID Tuner based on a CSV file of a Process Reaction Curve (PRC)**

> ***Notes and Limitations:***
>
> - _Assumes CV and PV data stored at 100ms intervals._
>
> - _Assumes there is a single step in CV._
>
> - _Ambient is calculated as an average of the PV prior to the step change._
>
> - _Doesn't work correctly with a ramp in CV or with multiple CV steps._
>  
>  
>  
> ***N.B.***  
> The PID tuning values are calculated for a PV with a standard range span of 100 in engineering units (e.g. 0-100 deg C or 50-150 deg F).              
> If the range of the PV has a different span the PID tuning values **may** need to be rescaled:
> 
>       Example 1: PV range of 200-400 deg C -> PID Gains x2
> 
>       Example 2: PV range of 75-100 deg C -> PID Gains x0.25
>  
>

To launch, use:
```
from pytunelogix.stage1 import csvtuner

csvtuner.main()

```
