KUKA Robot KRC0928 - EXPRESSION TYPE NOT “MODUS_T” 2265

EXPRESSION TYPE NOT “MODUS_T” 2265

This alarm indicates that an expression used in the KRL program does not have the required MODUS_T (mode structure) type. The compiler expected a MODUS_T data type but encountered a different type instead, preventing proper program compilation or execution.

Common Causes

  • Variable or expression declared with incorrect data type instead of MODUS_T
  • Type mismatch in function parameter passing where MODUS_T is expected
  • Attempting to assign a non-MODUS_T value to a MODUS_T variable
  • Incorrect structure initialization or casting of mode-related data
  • Using wrong variable name or referencing undefined MODUS_T object in expression

Troubleshooting Steps

  1. 1Review the KRL source code at the line indicated by the alarm to identify the problematic expression
  2. 2Verify that all variables used in the expression are declared with the correct MODUS_T data type
  3. 3Check function signatures and ensure parameters match expected MODUS_T types
  4. 4Confirm that any type conversions or assignments involving mode data are explicitly cast to MODUS_T
  5. 5Cross-reference variable definitions in included files or libraries to ensure consistent typing
  6. 6Recompile the program after corrections and verify the alarm code no longer appears
