Boot Project Load Failed (Insufficient License)

What does E3-46 mean?

The CPU was unable to load the boot project because it detected insufficient licensing for the application. This prevents the application from starting and running, indicating a licensing issue rather than a hardware fault. The PLC may enter demo or stop mode, rendering it inoperable for licensed features.
