Python Communication with PLC Training

Learn data logging, SQL, Excel reporting, GUI, MQTT, REST API, and EXE deployment. Build real-time SCADA tools using Python for automation systems.

Python Communication with PLC Course Content

• Python for Industrial Automation – with focus on data handling, reporting, SQL/Excel integration, GUI & EXE development, and cloud protocols (MQTT/REST).

✅ Week 1: Python Foundations for Industrial Systems

🐍 Python Setup & IDEs Install Python 3.x, pip, VS Code/Thonny; create a workspace with organized project structure for automation

🧠 Basic Syntax & Variable Types Use variables, strings, numbers, and booleans in formats similar to industrial tags (Temp_Act, Cp_Set)

🔁 Decision Logic & Looping Structures Build if, elif, else conditions and loops for simulation of machine control logic, alarms, or counters

📦 Functions & Modular Logic Write reusable logic blocks — e.g., temperature validation, efficiency calculation, log filtering

📂 File Handling (TXT/CSV) Read/write process data in .txt or .csv, similar to SCADA log export/import routines

🧪 Project 1: Simulated Tag Logger Log simulated temperature & process values into CSV format with timestamps (mimicking PLC to SCADA logging)

✅ Week 2: Time Handling, Data Structuring & Error Resilience

🕒 Time & Shift Calculations Use datetime for batch duration, shift schedules, time-based slicing of process data

➗ Math, Rounding & Calculations Calculate yield, efficiency, over-consumption using math, round(), and precision controls

📁 JSON Handling Store/retrieve structured tag data using JSON – prepares for REST, MQTT, and config files

🔄 Simulate Real-Time PollingUse loops + time.sleep() to poll or log simulated PLC data every X seconds

🔍 Try-Except for Error Handling Avoid crash in case of missing files, broken data, or bad input with proper exception catching

📊 Mini Project 2: Data Filter & Trend Preparer
Filter CSV tag data by time/ChargeNo and prepare timestamp-value pairs for Excel or charting

✅ Week 3: SQL, Excel Automation, and Python GUI

🗃️ Connect Python to SQL Server Use pyodbc or sqlalchemy to fetch batch/process data from WinCC SCADA database

🔎 SQL Query & Tag Filtering Filter records by ChargeNo, DateTime, BatchNo; display/log summary and actuals

📊 Excel Automation with xlsxwriter / openpyxl Generate formatted Excel reports with headers, colors, formulas, and charts

📁 Save Reports with Auto-Naming Use dynamic filenames with date/shift tagging (Report_2025-08-04_Shift1.xlsx)

🖥️ GUI with Tkinter Build popup interface for operator entry: ChargeNo, Start/End Time, Shift, Click to Generate Report

🧪 Project 3: GUI-Based Report Generator Standalone Python app with form input → fetch SQL data → create Excel report with trends, summary

✅ Week 4: Deployment, MQTT, REST API & Industrial Integration

📦 PyInstaller for EXE Conversion Convert Python + GUI into .exe file for use on SCADA systems without Python installation

🔐 EXE-Level Validation Add input checks, alerts, overwrite protection to ensure safe operation in plant environment

📶 MQTT Protocol Basics Publish/Subscribe simulated PLC tag values to Mosquitto broker using paho-mqtt
Use topics like /plant1/temp, /furnace1/status

🌐 REST API Integration Use requests to send batch reports or alarms to web dashboards or cloud APIs (POST, GET)

📡 Bi-Directional Cloud Sync Receive remote control commands or setpoints via MQTT/REST and act in Python app

🧪 Final Capstone Project:Complete Report Automation Tool:
✅ GUI Input → ✅ SQL Query → ✅ Excel Report → ✅ MQTT Alert → ✅ Packaged EXE
