1. 1

   Verify the specific instruction or function being called in the PLC program for correct syntax and usage, ensuring it aligns with the intended operation.

2. 2

   Check the configuration of any associated I/O modules, communication modules, or other devices in the I/O tree to confirm they are correctly defined, enabled, and functioning.

3. 3

   Inspect the PLC controller's firmware revision and model number against Rockwell Automation documentation to confirm that the requested function is supported by the installed hardware and firmware.

4. 4

   Review the controller properties, project settings, and security configurations within the programming software (e.g., RSLogix 500/5000, Studio 5000) for any global disables or restrictions that might prevent the function from executing.
