Safety Semantic Error: Backward jumps are not allowed.

This error message can only be reported if you are programming in an FVL (Full Variability Language) according to the IEC 61508 standard (system level programming) which allows the use of jumps in safety-related code.

A jump programmed in a safety-related code network jumps backwards in the code. This is not allowed.

Remedy:

  1. Double-click the error in the Error List to jump to the suspected code worksheet (where the code position is marked).
  2. Correct the code by either deleting the jump or by moving the jump label to a valid position.
