Alarm KRC0745

KUKA Robot KRC0745 - PROTOCOL VARIABLE DECLARED IMPLICITLY 1 2081

This alarm indicates that a variable or protocol element was used in the KRL program without being explicitly declared beforehand. The compiler detected an implicit declaration of a protocol variable, which violates KRL's strict type safety requirements and prevents program execution.

KUKA Robot KRC0745 - PROTOCOL VARIABLE DECLARED IMPLICITLY 1 2081

PROTOCOL VARIABLE DECLARED IMPLICITLY 1 2081

This alarm indicates that a variable or protocol element was used in the KRL program without being explicitly declared beforehand. The compiler detected an implicit declaration of a protocol variable, which violates KRL's strict type safety requirements and prevents program execution.

Common Causes

  • Variable used in code without prior DECL statement
  • Typo in variable name differs from original declaration
  • Missing data type specification in variable declaration
  • Protocol variable referenced before being defined in the program flow
  • Incorrect scope or visibility of declared variable

Troubleshooting Steps

  1. 1Review the KRL source code and identify all variables used near the error location
  2. 2Verify that each variable has an explicit DECL statement with proper data type before first use
  3. 3Check for spelling inconsistencies between variable declaration and usage throughout the program
  4. 4Ensure all protocol-related variables are declared with appropriate GLOBAL or LOCAL scope modifiers
  5. 5Consult the KRL program's function/module header to confirm variable declarations are in correct scope
  6. 6Recompile the program after corrections and verify the alarm no longer appears in diagnostics
