Codesys License Activation File

| Criterion | Score | Comment | |-----------|-------|---------| | Ease of use | 5/10 | Confusing .c2v/.v2c workflow for beginners | | Reliability | 6/10 | SoftContainer fragility hurts | | Security | 7/10 | Adequate for industrial use | | Portability | 4/10 | Tied too tightly to hardware fingerprint | | Documentation | 6/10 | Official docs exist but scattered | | Support | 5/10 | Distributor-dependent; CODESYS GmbH responsive only to direct customers |

Overall: 5.5/10 – Functional but frustrating. Works well if you standardize on dongles and avoid VMs. SoftContainer is a support trap.

| Feature | CODESYS | Siemens (ALM) | Rockwell (FactoryTalk) | |----------|---------|---------------|------------------------| | Dongle required | Optional | No (soft license only) | No (serial-based) | | Online deactivation | Yes (d2v) | Yes | No | | VM support | Poor (SoftContainer) | Good | Good | | Grace period on failure | None | 7-30 days | 7 days | | License Manager stability | Moderate | Good | Poor (historically) |

Step 1: Generate a Request File On the target device (offline), go to License Management → CmAct section → Click "Create Offline Request File". Save the *.ReqF file to a USB drive.

Step 2: Sign the Request Online Take the USB drive to an online PC. Go to the CODESYS Offline Activation Portal (login required). Upload the *.ReqF file.

Step 3: Generate a Response File The portal will encrypt a response file *.ResF. Download it to the USB drive. | Feature | CODESYS | Siemens (ALM) |

Step 4: Apply the Response Back on the offline target, click "Apply Offline Response File" in the License Management tab. Select the *.ResF file. Activation complete.

CODESYS (Controller Development System) is the gold standard for industrial control programming, used by hundreds of hardware manufacturers worldwide. Whether you are running a soft-PLC on a PC, configuring a Raspberry Pi, or deploying a headless industrial controller, one critical step must occur before your system goes into production: CODESYS license activation.

Without a valid, activated license, your runtime will operate in demo mode—typically limited to 2 hours of continuous operation. For any 24/7 industrial application or commercial product, proper license activation is non-negotiable. For critical infrastructure or military applications with no

This guide provides a deep dive into everything you need to know about CODESYS license activation, including methods for standard USB dongles, software containers (CmAct licenses), network licensing, and offline activation.

  • Activation fails on device
  • “License expired” or “feature locked”
  • Multiple licenses conflict
  • Offline activation file rejected
  • Licensing server unreachable (for network-based licensing)
  • IDE plugins not enabled after activation

    • 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).

    Beyond the base runtime, you may need to activate additional options:

    In all cases, repeat the Method A process—the additional feature will automatically be unlocked once the main license file is imported, provided the feature was included in your purchase.
