In the world of industrial automation, CODESYS (Controller Development System) stands as the de facto standard for IEC 61131-3 programming. However, moving from the free "demo" mode to a fully functional production environment requires navigating the CODESYS Licensing system. Unlike older software that relied on simple serial keys, modern CODESYS utilizes a container-based licensing model tied to hardware IDs.

The easiest and fastest way to activate your product is directly through the CODESYS Development System interface. Step 1: Open the License Manager codesys license activation

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.

The License Manager will display the available licenses in your ticket. Select the licenses you want to activate.

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.

In industrial environments, programming PCs and PLCs are often kept strictly offline for cybersecurity reasons. You can activate licenses offline using a three-step file exchange process requiring a second, internet-connected device. Step 1: Generate a License Request File (.WibuCmRaC) Activating Licenses on a PLC (Runtime License) (move

To ensure a smooth activation process, prepare the following items:

: Be careful with "Soft containers" on virtual machines or after hardware changes, as the license may become invalid if the hardware fingerprint changes significantly.

This method is performed directly through your web browser or via the CODESYS Development System.

Reboot your PLC and check the device log. If a license is missing or invalid, the runtime will typically log a warning and run in a limited demo mode (usually restricted to 2 hours of continuous operation). 6.

Before you start, you must choose where to keep your license. CODESYS gives you two choices.

If the target system lacks internet access, you must perform an :

Application-Based Licenses require specific versions to function: CODESYS Control SL and CODESYS Development System V3.5 SP19 Patch 1 or higher . Older software will not recognize the new license metrics. Ensure your software is up to date.

If you selected Device , click and choose your target controller from the network scan tree. Choose your container type: Softcontainer or Dongle . Step 3: Enter the Ticket ID Click the Install Licenses button. Select Activate License and hit Next . Paste your 25-character Ticket ID into the text field.

This is the fastest method for systems with internet access. Open License Manager : In CODESYS, navigate to Tools > License Manager Select Target Workstation (for engineering tools) or (for PLC runtime licenses). Choose Container : Select the appropriate SoftContainer from the list. Install License Install Licenses Activate License , and enter your
