用Python实时监控PLC数据
我想每秒钟监控PLC值,包括模拟值和数字值。我的当前代码能够读取值,但不会更新。我想我需要使用线程概念用Python实时监控PLC数据,python,time,real-time,plc,Python,Time,Real Time,Plc,我想每秒钟监控PLC值,包括模拟值和数字值。我的当前代码能够读取值,但不会更新。我想我需要使用线程概念 from Tkinter import * import Tkinter as tk from PIL import ImageTk, Image from cpppo.server.enip import client import thread root = tk.Tk() root.geometry("1920x1080") def AIn(Cfg_Tag,parent,Xaxis,
