USER PROGRAM INCOMPATIBLE WITH OS AT POWER-UP

What does 001A mean?

At power-up, the user program loaded into the controller is found to be incompatible with its Operating System (OS). This is a non-user fault preventing the controller from starting correctly, similar to a memory module incompatibility but occurring during initial program load.

• Controller OS version does not support features or instructions used in the user program.
• User program was developed for a different controller series or OS version.
• Corrupted program download that resulted in an incompatible state.
