KUKA Robot KRC0686 - DATA LIST NOT “PUBLIC” 2022

This alarm indicates that a KRL program object (module, function, or variable) named @P1@ is not declared with PUBLIC visibility, preventing access from external scopes or other program modules in the 2022 KRL standard. The compiler or runtime has detected an attempt to access a non-public object that requires public declaration for the intended use case.

KUKA Robot KRC0686 - DATA LIST NOT “PUBLIC” 2022

DATA LIST NOT “PUBLIC” 2022

This alarm indicates that a KRL program object (module, function, or variable) named @P1@ is not declared with PUBLIC visibility, preventing access from external scopes or other program modules in the 2022 KRL standard. The compiler or runtime has detected an attempt to access a non-public object that requires public declaration for the intended use case.

Common Causes

  • Object @P1@ is declared as PRIVATE or has no visibility modifier when PUBLIC is required
  • Attempting to call a function or access a variable from a different program module without proper PUBLIC declaration
  • KRL code was migrated from an older standard without updating visibility declarations to match 2022 syntax requirements
  • Incorrect scope hierarchy or namespace access in modular program structure
  • Library or include file contains objects that need PUBLIC declaration for cross-module reference

Troubleshooting Steps

  1. 1Locate the object @P1@ definition in the source code and verify its declaration statement
  2. 2Add or modify the visibility modifier to PUBLIC before the object declaration (e.g., PUBLIC FUNCTION myFunc or PUBLIC REAL myVariable)
  3. 3Ensure the calling module or function has proper INCLUDE or USE statements to reference the PUBLIC object if required by program structure
  4. 4Recompile the affected KRL program and check for any cascading visibility-related errors
  5. 5Review KRL 2022 documentation for visibility scope rules if migrating from previous standards
  6. 6Restart the KRC controller and reload the program to apply the visibility changes
