Siemens 840D 14080 - Channel block jump destination not found

Channel block jump destination not found

In conditional and unconditional jumps, the jump destination within the program must be a block with a label (symbolic name instead of block number). If no jump destination has been found with the given label when searching in the programmed direction, an alarm is output.

Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Common Causes

  • Typo or misspelling in the jump destination label name
  • Jump destination label does not exist in the program or was deleted
  • Case sensitivity mismatch between jump instruction and label definition
  • Jump direction is incorrect, causing search to miss the label in the opposite direction
  • Label syntax is invalid or does not meet program naming conventions

Troubleshooting Steps

  1. 1Verify the exact spelling and case of the jump destination label in both the jump command and the target block label definition
  2. 2Search the entire program file for the referenced label to confirm it exists and is defined correctly
  3. 3Check that the label is placed at the beginning of the target block using proper syntax (e.g., colon format per your programming standard)
  4. 4Review the jump direction logic in the conditional or unconditional jump statement to ensure it will search the correct program section
  5. 5Recompile or reload the program file into the control after making label corrections to clear the cached alarm
