Alarm KRC0726

KUKA Robot KRC0726 - AGGREGATE COMPONENT INITIALIZED MORE THAN ONCE 2062

This alarm indicates that an aggregate component (a structured data type or module) has been initialized or declared more than once within the same program scope or execution cycle. The KRL compiler or runtime environment detected a duplicate initialization attempt for <object name>, which violates the single initialization rule for aggregate components.

AGGREGATE COMPONENT INITIALIZED MORE THAN ONCE 2062

This alarm indicates that an aggregate component (a structured data type or module) has been initialized or declared more than once within the same program scope or execution cycle. The KRL compiler or runtime environment detected a duplicate initialization attempt for <object name>, which violates the single initialization rule for aggregate components.

Common Causes

  • Aggregate variable declared and initialized multiple times in the same program file
  • Include files or modules being loaded multiple times without proper header guards
  • Initialization code placed in both a function and its calling program
  • Global aggregate component re-initialized in a loop or repeated function calls
  • Conflicting variable definitions across linked program modules or libraries

Troubleshooting Steps

  1. 1Review the program source code and locate all declarations of <object name> to identify duplicate initialization statements
  2. 2Add include guards or conditional compilation directives to prevent multiple loads of shared modules
  3. 3Move aggregate initialization outside of loops or repeated execution blocks if applicable
  4. 4Verify that header files are not being included multiple times in the program chain
  5. 5Check linked modules and libraries for conflicting definitions of the same aggregate component
  6. 6Rebuild and recompile the KRL program after corrections, then clear the alarm and restart the controller
