Alarm KRC0999

KUKA Robot KRC0999 - COMBINED SIGNAL MORE THAN 32 BITS 2336

This alarm indicates that a combined signal definition in the KRL program exceeds the maximum supported bit width of 32 bits. The system cannot process signal combinations that require more than 32 bits of data storage or representation. This typically occurs when attempting to merge multiple signals whose total bit requirements surpass the 32-bit limit.

KUKA Robot KRC0999 - COMBINED SIGNAL MORE THAN 32 BITS 2336

COMBINED SIGNAL MORE THAN 32 BITS 2336

This alarm indicates that a combined signal definition in the KRL program exceeds the maximum supported bit width of 32 bits. The system cannot process signal combinations that require more than 32 bits of data storage or representation. This typically occurs when attempting to merge multiple signals whose total bit requirements surpass the 32-bit limit.

Common Causes

  • Combining too many individual signals into a single signal group without considering total bit width
  • Using signal data types with larger bit widths than necessary (e.g., INT instead of BOOL where applicable)
  • Incorrect signal definition syntax causing unintended bit allocation in the combined signal
  • Attempting to combine signals with incompatible data types that require excessive bit representation
  • Signal array or structure definition that accumulates bits beyond the 32-bit threshold

Troubleshooting Steps

  1. 1Review the signal combination definition in the KRL program and identify which signals are being combined
  2. 2Calculate the total bit width of all signals in the combination to confirm it exceeds 32 bits
  3. 3Reduce the number of signals in the combined signal group or split them into multiple smaller groups
  4. 4Optimize individual signal data types to use smaller bit widths (e.g., replace BOOL arrays with bit-packed structures)
  5. 5Consult the KUKA KRL documentation for maximum signal combination specifications and best practices
  6. 6Recompile the program after modifications and verify the alarm is resolved
