CODESYS is a widely used development environment for industrial automation, providing a platform to design, program, and configure controllers using IEC 61131-3 languages. License activation in CODESYS is more than a bureaucratic step: it’s the bridge that moves a solution from evaluation or development into dependable, secure operation on real hardware. This essay explains what license activation means in practical terms, why it matters, the common activation methods, typical pitfalls, and best practices for reliable deployments.
What a license does
Common activation workflows
Technical binding and security Licenses are generally bound to device-specific identifiers to prevent casual copying. Typical identifiers include MAC addresses, CPU serials, or unique runtime IDs. Stronger systems use cryptographic signing to ensure license integrity; the runtime verifies signatures and checks validity dates, feature sets, and usage constraints. License servers often use TLS and authentication to protect license requests.

Conclusion License activation in CODESYS is a crucial operational step that ensures authorized, feature-complete operation of industrial controllers. While activation mechanisms vary—dongles, files, online services, or license servers—the core challenges are consistent: binding licenses to device identities, ensuring continuity across hardware and network changes, and maintaining accurate records to avoid production interruptions. Planning for activation early, automating monitoring, and following vendor procedures turn a potentially disruptive administrative task into a predictable part of deploying resilient automation systems.

Your Complete Guide to CODESYS License Activation If you’re working in industrial automation, you’ve likely encountered CODESYS. It’s the "Swiss Army Knife" of PLC programming, used by hundreds of hardware manufacturers. While the development environment itself is often free to download, getting your runtime or specific libraries to work on your hardware requires a license.
Navigating CODESYS license activation can feel a bit like a maze if you don't know the path. Whether you are using a soft PLC on a Raspberry Pi or a high-end industrial controller, here is the step-by-step breakdown of how to get your system up and running. 1. Understanding the Two Types of Licenses
Before you start clicking buttons, you need to know where your license will live. CODESYS offers two main containers: codesys license activation
Soft Containers (Software-Based): The license is tied to the specific hardware footprint of your PC or PLC. It’s convenient because you don't need extra hardware, but if your hard drive fails or you change your motherboard, the license might become invalid.
Hard Keys (USB Dongles): The license lives on a physical CODESYS Key (USB). This is the most flexible option. You can move the USB stick from one controller to another, and the license follows the stick. 2. Pre-Requisites for Activation
To ensure a smooth process, make sure you have the following ready:
The Product Key: This is a 25-digit alphanumeric code provided by the CODESYS Store or your hardware vendor.
CODESYS Development System: Ensure you have the IDE installed on your PC.
Connection to the Target: Your PC must be able to "see" the PLC over the network.
Codemeter Runtime: This usually installs automatically with CODESYS, but it must be running in your system tray (the little grey or green "C" icon). 3. Step-by-Step Activation Process Method A: Activation via the CODESYS IDE (Standard) This is the most common method for most users. Open CODESYS: Launch your project or a blank project. Open License Manager: Go to Tools > License Manager.
Select the Target: Choose whether you are activating a license on the Device (the PLC) or the Workstation (your PC). If choosing Device, select your PLC from the network scan.
Choose Container: Select "Soft Container" or "Key," then click Activate License. Enter Product Key: Paste your 25-digit key.
Online Transfer: The wizard will connect to the CODESYS License Server and automatically download the license to your device. Method B: Offline Activation (The "Sneaker-Net" Method)
If your PLC is on a secure factory floor with no internet access, you’ll need to use the offline request method. CODESYS is a widely used development environment for
In the License Manager, select Activate License and choose Offline Request.
The software will generate a WibuCmRaC file (License Request File). Save this to a USB drive.
Take that file to a computer with internet and go to the CODESYS License Central website.
Upload your request file and enter your Product Key. The site will give you a WibuCmRaU file (License Update File).
Bring that file back to your PLC via the License Manager to complete the process. 4. Troubleshooting Common Issues
"License Container Not Found": Ensure your USB Key is plugged in firmly or that the Codemeter service is running.
"Invalid Ticket": Double-check for typos. It’s always best to copy-paste the key directly from your purchase email.
Connection Timed Out: Ensure your firewall isn't blocking the CODESYS IDE from reaching the internet license server (Port 443).
Hardware Changed: If you are using a Soft Container and replaced a part in your PC, you may need to contact CODESYS support to "restore" or "re-host" the license. 5. Best Practices for License Management
Always Backup: Once activated, take a screenshot of your License Manager screen.
Use Dongles for Critical Jobs: If a PLC fails in the field, you can simply plug the USB key into the replacement PLC and be back online in minutes. Common activation workflows
Keep your "Ticket" Safe: The 25-digit code is your proof of purchase. Treat it like cash!
Before activating, it is crucial to understand how CODESYS manages licenses.
On Windows:
Before starting the activation process, verify the following:
Cause: The persistent storage for licenses is incorrectly configured on the target.
Solution: Set the PlcLogic service to start after the filesystem mount. For embedded, ensure a battery-backed RTC is present (licenses check system time).
This is the most common method for embedded devices and development PCs.
Step 1: Locate the Runtime Open CODESYS IDE. In the device tree, double-click the "CODESYS Control ..." node (e.g., CODESYS Control Win V3).
Step 2: Open the License Management Tab Navigate to the "License Management" tab at the bottom of the editor window. You will see a section labeled "Software Container (CmActLicense)".
Step 3: Read the Container ID Click the "Read Container ID" button. A string of 20-30 alphanumeric characters will appear. This ID is the digital fingerprint of your target device. Copy it to clipboard or note it down.
Step 4: Retrieve the License from MyCODESYS Open a web browser, log into your MyCODESYS account. Go to "Licenses & Downloads" -> "My Licenses". Find your purchased product, click "Activate". You will be prompted to paste the Container ID you copied earlier.
Step 5: Download the License File
After pasting the Container ID, the CODESYS portal will generate an activation file (.lic or .license). Download it to your PC.
Step 6: Import the License into CODESYS Return to the CODESYS IDE on the License Management tab. Under "Activate/Import", click "Import License File". Browse to the downloaded file and select it. CODESYS will immediately push the license to the target device.
Step 7: Verify Activation Click the "Update" button. You should now see your license product name, serial number, and most importantly, "Status: Activated" and "Expiry: never" (or your maintenance date).
