Supervisory Control Tool implemented by Python

Monitor

A Simple Variable Supervision and Control application written in python

Usage

Step 1: Make a table

import monitor
from monitor import variable_model as vm

class VariableTable(monitor.Table):
    a = vm.PlainSupervised()
    b = vm.PlainSupervised()
    f = vm.FloatSupervised()
    g = vm.FloatSupervised(round_to=2)
    i = vm.ImageSupervised()
    j = vm.ImageSupervised()

    c = vm.PlainControlled(init=3.1415)
    
table = VariableTable()

Step 2: Assign table to app

import monitor
monitor.set_tracked_table(table)

Step 3: Run app in a new thread

The multiprocessing one has not yet developed, so use a new thread to start the server

import threading
import monitor

threading.Thread(target=monitor.app).start()

Step 4: Change variable in your app

Manipulate variables in the table instance as usual.

Notice: The variables end with Supervised are not readable, and the ones end with Controlled is not Writable

table.a = 233

# And later
table.a = 2333

Step 5: Monitor your variables in the browser
