What status flag indicates a normal scan of the routines?

The status flag that indicates a normal scan of the routines is S:FS. This flag, known as the Fault Status flag, provides insight into the current operation of the ControlLogix processor. When S:FS is set to 0, it signifies that the scan of the routines is proceeding without faults, indicating that the program is executing successfully. It reflects that the processor has completed its tasks in a standard operational mode, with no errors or issues affecting the routine scans.

Understanding this flag is crucial for system diagnostics and ensuring that the program operates smoothly. It allows programmers and operators to verify that the Controller is performing as expected and can help in troubleshooting if any anomalies arise.
