SQO/SQC/SQL OUTSIDE OF DATA FILE SPACE

Hva betyr 0032 ?

A sequencer instruction (SQO - Sequencer Output, SQC - Sequencer Compare, or SQL - Sequencer Load) has a length or position parameter that attempts to reference memory locations outside of the entire data file space. This is a recoverable fault, indicating an out-of-bounds memory access error in the program.

• Length or position parameter in a sequencer instruction (SQO, SQC, SQL) is misconfigured.
• Sequencer instruction attempting to read or write data beyond the bounds of its designated data file.
• The data file size defined for the sequencer is too small for the programmed length/position.

1. 1

   Correct the program to ensure that the length and position parameters of SQO, SQC, and SQL instructions do not point outside the defined data file space.

2. 2

   Recompile and reload the corrected program into the controller.

3. 3

   Enter the Run mode after the program is successfully reloaded.
