Error on renumbering. state restored.

The softkey "Renumber" was pressed in the program editor. This caused an error during serial numbering that damaged the program in the memory, making it necessary to reload the initial program into the memory. The program was not renumbered.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Corrupted program structure in memory preventing sequential renumbering operation
  • Insufficient memory space available for renumbering process completion
  • Invalid or malformed program syntax before renumbering attempt
  • Interrupted renumbering operation due to power loss or system shutdown
  • Program contains unsupported characters or formatting in line identifiers

Troubleshooting Steps

  1. 1Verify the program file integrity by reloading the original program from external storage and attempting renumbering operation on fresh copy
  2. 2Check available system memory and clear unnecessary files or programs from CNC memory to ensure adequate space for renumbering
  3. 3Review program code for syntax errors or irregular line numbering sequences that may interfere with renumbering algorithm
  4. 4Use the program editor's validation or diagnostic function to scan for structural issues before attempting renumbering again
  5. 5If renumbering repeatedly fails, reload the backup program version and manually renumber critical sections or export program to external editor for renumbering offline
