pytunelogix

Python PID Tuner for ControlLogix

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)

Assumes CV and PV data stored at 100ms intervals.

To launch use:

from pytunelogix.stage1 import csvtuner

csvtuner.main()

To launch use:

from pytunelogix.simulate import simulator

simulator.main()
