Friday, 4:45 PM. Junior engineer Lisa added a new I/O rack. She copied a potential definition from an old schematic — naming it 24V_AUX instead of PE_24V_MAIN.
Klaus’ validation code ran during the nightly build.
Result: Build failed. Error logged:
Wrong potential name: 24V_AUX at Page 47 / I/O Rack 3
The term "Codel" (often misspelled or shortened from “code list” or “coding logic”) refers to the internal numerical and alphanumeric identifiers that Eplan uses to track every component, connection, and property within a project.
When you run a validation check, Eplan generates a validation log that contains:
For example, a validation codel like "20011" might indicate "Device tag assigned multiple times," while "20115" could mean "Missing potential definition on a power supply."
These codels are essential for debugging because they point directly to the root cause, rather than generic error messages. Eplan P8 2.0 Validation Codel
Sometimes, Eplan P8 2.0 throws a generic error or freezes during validation. This is often due to:
In these cases, the validation codel is not displayed. Instead, check the Windows Event Viewer or Eplan’s internal log file located at:
C:\Users\[YourName]\AppData\Roaming\EPLAN\Log\
Look for lines containing Validation Error or Codel.
To achieve a zero-error validation in Eplan P8 2.0 consistently, follow these best practices:
If you have a specific error message (e.g., "License not found" or "Invalid Product Key"), please provide that specific text for more targeted troubleshooting. Using official channels ensures your engineering data remains safe and your projects are stable.
In EPLAN Electric P8 2.0, Validation Codes are primarily used for software licensing and activation. However, if you are looking for "validation" as a project-quality feature, this is managed through the Project Verification Check Runs EPLAN Help 1. Licensing & Activation Codes For version 2.0, a validation code is a 16-digit alphanumeric code Friday, 4:45 PM
used to activate the software license on a specific computer. Generating the Code
: It is generated based on your unique Serial Number and Hardware ID (or dongle ID). Entry Point : During installation or via the EPLAN License Client , you enter the code in the dialog box to unlock the software. Entitlement ID (EID)
: In newer versions, this has largely replaced the "unlock code" concept, but for legacy 2.0 systems, the specific validation code is still the standard. Google Groups 2. Project Data Validation (Verification) If your goal is to "validate" project data, EPLAN uses a Project Verification process to ensure your work meets specific standards. EPLAN Help Reference Comparison
: You can compare an "incoming" project against a "reference" project ( file) to see if settings or properties have changed. Check Run Schemes
: You can create custom schemes to define what constitutes an error, warning, or note. Message Management : Access this via Project Data > Messages > Check Project

The validation code in EPLAN Electric P8 2.0 is a legacy licensing mechanism used to authorize the software's use on a specific workstation. In older versions like 2.0, this code was typically tied to a physical USB dongle
(hardware key) and served as the unlock key for the specific modules and systems purchased. Key Concepts of EPLAN 2.0 Validation
: The code verifies that the serial number and customer ID match the licensed product, enabling the software to run on the machine where the dongle is connected. Legacy vs. Modern : In version 2.0, the Validation Code
was the standard. In newer versions (starting around 2.4/2.5 and higher), EPLAN transitioned to the Entitlement ID (EID)
, which allows for online activation without a physical dongle. Dependency : For local licenses, version 2.0 requires both the serial number validation code , along with a plugged-in USB dongle to function. How to Obtain or Use the Code Eplan P8 2.1 Validation Code - Weebly
When the check is complete, the output window displays results in a specific format. Understanding how to read the output is the first step to resolution.
