Cyclikal Temperature-Box-Controller

This is a GUI for controlling Cyclikal Temperature Boxes and logging their temperatures.

Installation

Install requirements.

pip install -r requirements.txt

This will install pyserial, minimalmodbus, and the last open version of pySimpleGUI.

The settings.json file controls the behavior of the application, including:

The number of panels in the GUI ("boxes")
The directory where the data is logged ("data_directory"). Note that if this directory must already exist.
The minimum amount of time in seconds between logged datapoints ("read_delta")
The sleep time in seconds between checking the boxes ("sleep")

A basic settings file for two boxes would look like this:

{
    "data_directory":"./data",
    "read_delta":60,
    "sleep": 1.0,
    "boxes": [
        {
            "address": 1,
            "port": "COM6",
            "name": "Box 1",
            "protocol":[],
            "state":{"status":"unknown"}
        },
        {
            "address": 2,
            "port": "COM7",
            "name": "Box 2",
            "protocol":[],
            "state":{"status":"unknown"}
        }
    ]
}

Note that the "protocol" and the "state" will be populated by the application upon running. The "address" and the "port" can be changed in the GUI. The application should work whether the boxes are connected by USB or RS485. The "address" parameter is the address set on the physical PID controller (Novus N1050). For RS485 communications the application assumes the controllers are set to a baudrate of 9600 and a parity of None.

Usage

The application is launched by running the gui.py file in the temperaturebox folder:

python gui.py

The GUI provides a simple way to designate set temperatures and times for your Cyclikal temperature boxes and having the data logged in a simple CSV file.

Common Gotchas

The communication with the boxes fails due to the controllers not being set to baud 9.6 and Prty NONE. This can be changed on the physical PID controller (Novus 1050).
The data does not get logged because the directory specified in the settings file does not exist.
Getting a splash screen for paying for PySimpleGUI. This is solved by installing the last open version as specified in the requirements.txt file.
