Alarm KRC0873

KUKA Robot KRC0873 - “DEL” MUST FOLLOW 2209

This alarm indicates a syntax error in the KRL program where a DEL (delete) statement has been encountered in an incorrect sequence. The DEL instruction must immediately follow a 2209 statement (typically a PDAT or similar data declaration) in the program structure. This violation of mandatory statement ordering prevents the program from being compiled or executed.

KUKA Robot KRC0873 - “DEL” MUST FOLLOW 2209

“DEL” MUST FOLLOW 2209

This alarm indicates a syntax error in the KRL program where a DEL (delete) statement has been encountered in an incorrect sequence. The DEL instruction must immediately follow a 2209 statement (typically a PDAT or similar data declaration) in the program structure. This violation of mandatory statement ordering prevents the program from being compiled or executed.

Common Causes

  • DEL statement placed in wrong location within the program, not directly after the required 2209 statement
  • Missing or improperly formatted 2209 statement before the DEL instruction
  • Incorrect program structure or flow with intervening statements between 2209 and DEL
  • Copy-paste error resulting in DEL statement being separated from its required predecessor
  • Corrupted or incomplete program file with broken statement sequence

Troubleshooting Steps

  1. 1Locate the DEL statement in the KRL source code that triggered the alarm
  2. 2Identify the preceding 2209 statement and verify it is the immediate statement before DEL
  3. 3Remove any statements or code blocks positioned between the 2209 statement and the DEL instruction
  4. 4Verify the syntax and completeness of the 2209 statement according to KRL language specification
  5. 5Reorganize the program structure to ensure DEL directly follows 2209 with no intervening code
  6. 6Recompile the program and verify the alarm is resolved; if persisting, review the complete program logic against KRL standards
