File Set Error (Boot Setting)
Mitsubishi Electric · MELSEC-Q/L Common Instruction
What does 2400 mean?
This error occurs when the boot setting has not been configured in the PLC parameter, preventing the execution of a program replaced by the PSWAPP instruction. The system expects a program to be designated for boot. This ultimately prevents the newly swapped program from running, indicating a missing or incorrect system configuration for program execution.
Common Causes
- The PLC parameter's boot setting is not configured for a specific program name.
- Attempting to execute a program swapped by the PSWAPP instruction without a corresponding boot setting in PLC parameters.
- The program setting in the PLC parameter for the corresponding program name is incorrect or undefined.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Access the PLC parameters via the programming software.
- 2
Configure the boot setting in the PLC parameter to the program name intended for execution.
- 3
If the program setting in the PLC parameter is also incorrect, update it for the corresponding program name.
- 4
If the program was recently modified or transferred, write the correct program to the CPU module again after adjusting boot and program settings.
