KUKA Robot KRC0989 - TYPE UNKNOWN 2326

TYPE UNKNOWN 2326

This alarm indicates an unknown type error in the KRL runtime environment, specifically related to internal error code 2326. The error typically occurs during program execution when the system encounters an undefined or unsupported data type that cannot be properly interpreted or processed.

Common Causes

  • Incorrect variable declaration or type mismatch in KRL source code
  • Corrupted or incompatible compiled program file (.src or .dat)
  • Memory corruption in the robot controller affecting type information
  • Using unsupported or obsolete KRL syntax for the current firmware version
  • Loading a program compiled with a different or incompatible KRC version

Troubleshooting Steps

  1. 1Verify the KRL program syntax and all variable type declarations match the KRC firmware documentation
  2. 2Recompile the affected KRL program using the current KUKA IDE and firmware version
  3. 3Delete all compiled program files (.src and .dat) and recompile from source code
  4. 4Check the robot controller firmware version and update if necessary to match program requirements
  5. 5Isolate the error by commenting out sections of code and recompiling to identify the problematic statement
  6. 6If error persists, perform a complete controller restart or reset the KRC system to factory defaults and reload programs
