Summary of the Video: Tutorial PLC Siemens S7-1200

The video provides a comprehensive tutorial on the Siemens S7-1200 series PLCs, focusing on both hardware and software aspects. The presenter introduces the Siemens S7-1200 PLC, discusses its features, and demonstrates how to program it using the TIA Portal software.

Main Ideas and Concepts:

• Introduction to Siemens S7-1200 PLC:
  • The S7-1200 series is a programmable logic controller (PLC) that can be powered by direct current (DC) and has various input/output configurations.
  • The presenter highlights the specific model (121C) and contrasts it with other models that may use relay outputs.
• Software Overview:
  • The programming software used for the S7-1200 is called TIA Portal (version 13 in this tutorial).
  • The software allows users to create projects, configure hardware, and program the PLC using ladder logic.
• Creating a New Project:
  • The presenter demonstrates how to create a new project in TIA Portal, including naming the project and specifying its parameters.
• Hardware Configuration:
  • The tutorial shows how to add a new device in the project tree and detect the connected PLC.
  • It explains the importance of matching the firmware version of the PLC with the software for successful detection.
• Programming Basics:
  • The video introduces the concept of ladder programming and how to create a simple start/stop program using two inputs and one output.
  • The presenter explains the addressing system for inputs and outputs in the PLC, using specific examples.
• Program Development:
  • The presenter details the process of adding programming blocks and creating a basic control program that includes interlocking for retaining output states.
  • The program is designed to turn on an output when a start button is pressed and turn it off when a stop button is pressed.
• Downloading and Monitoring the Program:
  • The tutorial explains how to download the program to the PLC and monitor its execution in real-time.
  • The presenter demonstrates how to check the status of inputs and outputs while the program is running.
• Final Notes:
  • The importance of downloading changes made in the program to the PLC is emphasized.
  • The video concludes with an invitation for viewer comments and a promise for future tutorials.

Methodology/Instructions:

• Creating a New Project:
  • Open TIA Portal.
  • Create a new project with a specified name, route, author, and comments.
• Adding a Device:
  • Navigate to the project tree.
  • Add a new device by double-clicking and selecting the appropriate controller type.
  • Specify the firmware version and detect the connected PLC.
• Programming Steps:
  • Access the main programming block (OB1).
  • Use ladder logic to create a start/stop program.
    • Use normally open (NO) and normally closed (NC) contacts for inputs.
    • Assign addresses to inputs (e.g., I0.3, I0.4) and outputs (e.g., Q0.0).
    • Implement interlocking to retain output state.
• Downloading the Program:
  • Use the "Download to device" option in TIA Portal.
  • Ensure the PLC is in stop mode before downloading.
  • After downloading, monitor the program's execution.

Speakers/Sources Featured:

• The presenter of the tutorial (name not specified).
