Eplan P8 2.0 Validation Codel ⭐

The Phantom Bus Error

Prologue: The 2.0 Upgrade

Mechatronics AG had just migrated from Eplan P8 1.9 to 2.0. Senior engineer Klaus found a new feature: Validation Codel — a C#-based API to automatically check project rules.

: You can compare an "incoming" project against a "reference" project ( file) to see if settings or properties have changed. Check Run Schemes Eplan P8 2.0 Validation Codel

To get the most out of Eplan P8 2.0 validation code, designers and engineers should follow best practices, including: The Phantom Bus Error Prologue: The 2

You can also export the scheme as an .xml file to share with team members, ensuring consistent validation across all projects. Unconnected Pins: Detects pins or contacts on symbols

  • Unconnected Pins: Detects pins or contacts on symbols that lack a connected conductor.
  • Duplicate References: Flags devices or assemblies sharing the same functional or device reference where uniqueness is required.
  • Missing Part Data: Identifies devices without required manufacturer or ordering data.
  • Terminal Overload: Checks if terminal strip allocation exceeds capacity or violates wiring rules.
  • Cross-Reference Mismatches: Ensures device references and page cross-references match bi-directionally.
  • PLC I/O Mapping Errors: Validates consistency between PLC channels and assigned signals.
  • Incomplete Device Properties: Ensures mandatory properties (e.g., voltage rating, current rating) are filled.

Summary

EPLAN P8 2.0's validation codes are not just error messages; they are diagnostic tools that reflect the database integrity of your project. While the specific numbers (like 002 or 033) are standard, the key to efficient troubleshooting lies in using the Message Management system to trace the logic back to the specific symbol or connection point causing the disruption.

Have a specific validation codel that’s driving you crazy? Leave a comment below with the number, and we’ll help you decode it!

  1. Eplan reads the dongle serial number and CipherBox ID.
  2. It computes a hash using:
    ValidationCode = Base64(SHA1(DongleID + ProductCode + Salt))
    where Salt is a per-installation random value stored in %PROGRAMDATA%\Eplan\License\license.key.
  3. This code is sent to Eplan’s activation server to unlock the product.
