Скачать или смотреть Siemens PLC & Python Snap7 Tutorial – Read&Write Strings in Siemens PLC (S7-1200/1500)

In this Python Snap7 tutorial, you will learn how to read and write STRING data types in a Siemens PLC using the Snap7 library. This PLC programming guide explains how to connect Python to Siemens S7-1200 and S7-1500 PLCs, locate string variables inside Data Blocks, and transfer data between Python and the PLC.

We demonstrate how to install and configure python-snap7, establish communication with the PLC, and correctly handle the special format of STRING data in Siemens PLCs. You will learn how to extract string values from Data Blocks, decode them into Python-readable format, and send new string values back to the PLC for real-time control or monitoring.

This tutorial is ideal for automation engineers, PLC programmers, and Python developers who want to integrate industrial systems with Python for tasks like HMI data exchange, database logging, or machine communication. The Snap7 library provides a flexible way to read and write PLC strings, integers, floats, and other data types, making it a powerful tool for industrial automation.

By the end of this video, you will be able to:
Connect Python to Siemens PLC using Snap7
Read STRING data from PLC Data Blocks
Write STRING data to PLC Data Blocks
Understand Siemens PLC string memory structure
Troubleshoot PLC-Python string communication issues
