  1. What Validation Code is and when to use it
  • Validation Code (VC) is a user-definable rule system in EPLAN that evaluates project objects (symbols, devices, pages, macros, properties) and reports nonconformances. Use it to enforce naming conventions, terminal numbering, missing attributes, manufacturer/ERP parts, wiring rules, and company-specific standards.
  1. Preparation — project and environment settings
  • Open the project in EPLAN Electric P8 2.7.
  • Ensure project templates, parts database (parts management), and macros are up to date.
  • Enable the Validation Code module (if your license separates modules).
  • Open: Utilities -> Validation (or Project -> Verify/Validation depending on UI layout).
  1. Creating a new Validation Code Steps:
  1. Open the Validation Code editor: Utilities -> Validation -> Validation Code.
  2. Create a new Validation Code set: File -> New. Give it a clear name (e.g., "Company_Standards_VC").
  3. Add checks by creating individual rules. Each rule has:
    • Object type to evaluate (Page, Device, PartAssignment, Terminal, Connection, Symbol, Macro, etc.)
    • Selection filter (scope: current page, project, single device class)
    • Condition(s) — logical expression(s) that must be true to pass
    • Message text and severity (Error/Warning/Info)
    • Optional quick-fix action (if available)
  4. Save the Validation Code set and assign it to the project or keep as global template.
  1. Common useful checks — examples with steps

Example A — Missing Tag or Device Identifiers Goal: Flag devices without a device tag (designation) or without an assigned device reference. Implementation:

  • Object type: Device
  • Condition: Device.Designation IS EMPTY OR Device.MachineTag IS EMPTY (use available field identifiers)
  • Message: "Device missing designation or machine tag"
  • Severity: Error
  • Scope: Entire project

Example B — Incorrect Page Name Format Goal: Enforce page names like "S1-01_Schematic" Implementation:

  • Object type: Page
  • Condition: NOT RegexMatch(Page.Name, "^S[0-9]+-[0-9]2_.+$")
  • Message: "Page name does not match required pattern Sn-pp_description"
  • Severity: Warning
  • Scope: Project

Example C — Missing Manufacturer/Article Number on Parts Goal: Ensure each part has manufacturer and article number assigned. Implementation:

  • Object type: PartAssignment (or Device -> Part)
  • Condition: Part.Manufacturer IS EMPTY OR Part.ManufacturerMaterialNumber IS EMPTY
  • Message: "Part missing manufacturer or article number"
  • Severity: Error
  • Scope: Project

Example D — Duplicate Terminal Tag on Terminal Strips Goal: Detect terminal points with identical tags within a terminal strip. Implementation:

  • Object type: Terminal
  • Condition: Terminal.Tag duplicates within TerminalStrip context (use grouping/count functions or script-based VC)
  • Message: "Duplicate terminal tag on strip"
  • Severity: Error
  • Scope: Terminal strips in project

Example E — Cross-reference / Wiring Missing Connection Goal: Detect device pins not connected (floating terminals). Implementation:

  • Object type: ConnectionPoint/FunctionConnection
  • Condition: ConnectionPoint.Connected = FALSE
  • Message: "Terminal/pin not connected"
  • Severity: Warning
  • Scope: Entire project

Notes: Some complex checks (duplicates, regex, multi-object comparisons) may require scripting support or using the more advanced VC options (expressions, macros, or API-based checks). If EPLAN’s built-in VC expressions are limited, use EPLAN Electric P8 API (C#/.NET) to implement complex validators and register results as project messages.

  1. Running validation and interpreting results
  • Run: Utilities -> Validation -> Execute Validation or Project -> Verify -> Run Validation.
  • Scope options: Current page, selected pages, or whole project.
  • Results window lists each violation with object link, message, severity, and page/object context.
  • Double-click a result to jump to the object in the schematic or parts list.
  1. Fixing issues and automating fixes
  • Manual: Double-click result → edit object properties → save.
  • Bulk changes: Use Find & Replace, Global edit for properties, or Excel export/import (Parts/Devices) to update many items.
  • Quick-fix actions: When creating a rule, you can sometimes attach actions (e.g., auto-assign a default manufacturer or set a default tag prefix). For advanced auto-fixes, write a script using the EPLAN API to:
    • Iterate over violation list
    • Modify properties
    • Re-run validation
  • Example auto-fix script actions: fill missing manufacturer from parts template, auto-number terminals, normalize page names.
  1. Best practices and tips
  • Start with non-blocking rules (Warnings) to minimize disruption; raise to Errors once team adapts.
  • Version your Validation Code with project templates so standards are reproducible.
  • Use regex and standardized property names to keep checks robust.
  • Combine VC with graphical rules and plot frame templates for consistent deliverables.
  • Document each rule (purpose, severity, intended fix) and share with the engineering team.
  • Back up your VC sets and include them in company template repositories.
  • For very advanced checks (cross-object consistency, database lookups), build an API-based validator and integrate it into project export or build pipelines.

Quick checklist to implement VC in a new project

  1. Create/choose VC set.
  2. Add core rules: missing tags, missing manufacturers, unconnected pins, page name format.
  3. Run validation on the whole project.
  4. Triage results: fix critical Errors first.
  5. Add automated fixes where safe.
  6. Iterate and expand rule set.

If you want, I can:

  • Provide ready-to-import rule definitions for the examples above formatted for EPLAN 2.7 (declare which checks you want prioritized), or
  • Draft a short C# API example that enumerates devices and reports the same checks as Validation Code.

Part 2: The Step-by-Step Process of Generating a Validation Code

If you have a legitimate license for EPLAN P8 2.7, here is the official workflow to generate and apply your Validation Code.

Why Version 2.7 Specifically?

EPLAN P8 2.7 represents a transitional period. Earlier versions relied heavily on green USB dongles (hardware keys). Version 2.7 made significant strides in soft-licensing (pure software-based activation) but retained compatibility with dongles. Consequently, "Validation Code Eplan P8 2.7" queries usually arise from users employing the EM (Electrical Management) / Professional Soft-Licensing method.

Error 4: License Manager Crashes When Entering Code

Cause: Corrupted user profile or permissions issue in Windows Registry. Solution:

  1. Uninstall EPLAN License Manager.
  2. Delete the folder C:\Program Files\EPLAN\Common\LicenseManager
  3. Delete registry keys (Caution) under HKEY_CURRENT_USER\Software\EPLAN\Licensing
  4. Reinstall License Manager and retry.

Error 3: The Validation Code field is greyed out

Cause: You are trying to use a soft licensing validation code on a system expecting a dongle (or vice versa). Solution: Check your license file extension. .LIF files are for soft licensing. USB dongles require you to install the EPLAN Dongle Driver and do not use validation codes at all.
