Allen-Bradley · MicroLogix 1400 Programmable Controllers
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.
Click steps to track your progress.
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.
Recompile and reload the corrected program into the controller.
Enter the Run mode after the program is successfully reloaded.
