BSL/BSR/FFL/FFU/LFL/LFU CROSSED DATA FILE SPACE

Allen-Bradley · MicroLogix 1400 Programmable Controllers

¿Qué significa 0033 ?

The length or position parameter of a Bit Shift Left (BSL), Bit Shift Right (BSR), Find First Last (FFL), Find First Unset (FFU), Look For Last (LFL), or Look For Unset (LFU) instruction references memory locations outside of the entire data file space. This is a recoverable fault, indicating an out-of-bounds memory access error.

Causas comunes

  • Length or position parameter in a BSL, BSR, FFL, FFU, LFL, or LFU instruction is misconfigured.
  • Instruction attempting to access data beyond the bounds of its designated data file.
  • The data file size defined is too small for the programmed length/position parameters.

  2. 2

    Recompile and reload the corrected program into the controller.

  3. 3

    Enter the Run mode after the program is successfully reloaded.
