KUKA Robot KRC0739 - ASCENDING INDICES EXPECTED 2075

ASCENDING INDICES EXPECTED 2075

This alarm indicates a syntax error in KRL code where array or list indices are not in ascending order as required by the compiler. The KRL parser expects indices to be declared or referenced in strictly ascending numerical sequence, and the code violates this requirement at the point specified in the error message.

Common Causes

  • Array indices declared out of ascending order in dimension statement
  • Incorrect index ordering in multi-dimensional array declarations
  • Manual index specification in array initialization not in ascending sequence
  • Copy-paste error resulting in reversed or non-sequential index values
  • Attempting to use descending indices where ascending order is mandatory

Troubleshooting Steps

  1. 1Review the KRL source file at the line indicated in the alarm message
  2. 2Identify all array or list declarations with explicit index specifications
  3. 3Verify that all indices are arranged in strictly ascending numerical order from left to right
  4. 4Correct the index sequence to ascending order, for example change [5,3,1] to [1,3,5]
  5. 5Check for any dynamic index assignments and ensure they respect ascending order requirements
  6. 6Recompile the KRL program and verify the alarm is resolved
