KUKA Robot KRC0763 - VARIABLE NOT DECLARED IN DATA LIST 2099

VARIABLE NOT DECLARED IN DATA LIST 2099

This alarm indicates that a variable referenced in the KRL program has not been properly declared in the data list section of the program or its associated data file. The compiler encountered an undeclared identifier during the compilation phase, preventing successful program execution.

Common Causes

  • Variable name is used in the program but missing from the DECL section or .DAT file
  • Typo or case sensitivity mismatch in variable name between declaration and usage
  • Variable declared in wrong scope or in a different module without proper access declaration
  • Missing GLOBAL keyword for variables that need to be accessible across multiple program files
  • Variable declaration file (.DAT) is not properly linked or referenced in the program

Troubleshooting Steps

  1. 1Review the error message to identify which variable name (@P1@) is undeclared
  2. 2Check the DECL section at the beginning of the KRL program file for the variable declaration
  3. 3Verify the variable name spelling and case sensitivity matches exactly between declaration and usage
  4. 4If the variable should be global, ensure it is declared with the GLOBAL keyword in the appropriate data file
  5. 5Confirm that any referenced .DAT (data) files are properly included and linked in the program structure
  6. 6Recompile the program after making corrections to resolve the undeclared variable error
