What is WinCC Unified?

WinCC Unified is Siemens’ next-generation SCADA and HMI platform designed for Industry 4.0 applications. It supports scalable and flexible visualization across devices—from small HMIs to large SCADA systems—using a modern, web-based interface.

Step 1: Prepare Your System

Before you begin installation, ensure your system meets the minimum requirements:

  • Windows 10 or later (64-bit)

  • At least 8 GB RAM (16 GB recommended)

  • Minimum 10 GB free disk space

  • Siemens TIA Portal V17 or newer (WinCC Unified is integrated here)

Step 2: Install TIA Portal and WinCC Unified

  1. Download the software: Get the official TIA Portal installer including WinCC Unified from Siemens’ website or your Siemens distributor.

  2. Run the installer: Follow the on-screen prompts. Choose the “Complete installation” option for all features.

  3. Activate licenses: Use Siemens License Manager to activate the necessary licenses for WinCC Unified.

Step 3: Create a New WinCC Unified Project

  • Open TIA Portal.

  • Click Create new project, give it a meaningful name, and click Create.

  • In the project view, right-click Visualization and select Add new WinCC Unified Runtime.

  • Choose the target device (HMI panel, PC, or Web Runtime) according to your needs.

Step 4: Configure Your HMI Screens

  • Use the drag-and-drop editor to add buttons, indicators, and other controls.

  • Configure properties like colors, text, and behavior in the Properties panel.

  • Set up tags to link controls with your PLC variables for real-time monitoring and control.

Step 5: Connect Your PLC

  • Add your PLC device to the project if not already done.

  • Establish communication by configuring the interface (e.g., Profinet).

  • Link PLC variables (tags) to your HMI elements for seamless data exchange.

Step 6: Test and Deploy

  • Use the Simulate Runtime option to test your screens without hardware.

  • After verifying functionality, download the project to your HMI or SCADA runtime device.

  • Monitor and control your process live!

Tips for Beginners

  • Start simple: Build a basic screen and gradually add complexity.

  • Use Siemens’ online documentation and tutorials for extra help.

  • Keep your tags and screens organized for easier maintenance.
