What is TIA Portal?
The Totally Integrated Automation Portal (TIA Portal) by Siemens is an engineering software used for programming, configuring, and commissioning automation devices such as PLCs, HMIs, and drives. It provides a unified environment that allows users to develop and manage automation projects efficiently.
Whether you’re working on a small machine or a complex industrial system, TIA Portal helps streamline the process—from hardware configuration to software development and diagnostics.

Changing the IP Address of the Computer
To establish communication between your PC and the PLC (CPU), both devices must be on the same IP subnet. This ensures that they can “see” each other over the network. In most cases, especially during initial setup or testing, it’s best to assign a static IP address to your PC.
You can configure the static IP via the Network Adapter Settings in Windows. Choose the Ethernet adapter you’ll use to connect to the PLC, and set an IP address that matches the PLC’s subnet (e.g., if the PLC is 192.168.1.1, you can assign 192.168.1.198 to the PC, with subnet mask 255.255.255.0).

Changing the IP Address of the CPU
There are two main ways to change the IP address of a Siemens CPU (PLC)
1. Directly from the device screen (if available)
- If your CPU or HMI panel includes a display, you can navigate through its menu to configure the IP address manually. This is useful for quick changes without a PC connection.
2. Via TIA Portal:
- You can also assign an IP address through TIA Portal. Open an existing project or create a new one. In the project view, go to the Online access tab (bottom-left corner), select the correct network interface (e.g., your Ethernet adapter), and click “Update accessible devices”. Once the CPU is detected, right-click on it and choose “Online & Diagnostics“.
- From the diagnostics panel, go to Functions → Assign IP Address. Here you can set both the IP address and the PROFINET device name.
⚠️ Important: If you’re using an existing project, make sure to retrieve the correct PROFINET device name from the Device & Networks section. Since the communication uses the PROFINET protocol, both the IP address and the device name must match exactly for successful connection and project download.
