Press PROG key, then select DIRECTORY soft key to display all registered programs. Verify the conflicting O-number exists in memory and note its size and date.

If the existing program can be deleted, select the program using cursor keys, press DELETE soft key, then EXEC to remove it. If program protection is active, check parameter 3202#0 (SPE) bit.

Verify program is not needed for production before deletion. Back up critical programs to external media first.

Check parameter 3107#1 (OPT) to verify overwrite function availability. If set to 1, use OPRT soft key in EDIT mode, select O SEARCH, input the program number, and enable overwrite before re-transferring.

Alternatively, rename the incoming program to an unused O-number before transfer. Check parameter 3107#5 (NE9) for 9-digit program number capability if using extended O-numbers.

Navigate to SYSTEM > PARAM and check parameter 0020 (I/O channel settings). Verify bits for input/output device match your transfer method (RS-232C, memory card, Ethernet).

Check parameter 3107 settings: bit 1 (OPT) enables overwrite operation, bit 4 (NCR) controls collation function. Set 3107#1=1 to allow program overwrite during transfer operations.

Setting OPT bit allows overwriting without confirmation - ensure operators are trained on this behavior.

For DNC operations, verify parameter 0100 (I/O time-out) and 0101-0104 (baud rate, stop bit, parity settings). Communication errors may cause incomplete program deletion before new transfer.

If using FANUC LADDER or PMC-controlled data transfer, check ladder logic for I/O Link signals (F-register addresses) that control overwrite enable signals before program input operations.

Press SYSTEM key, select CARD soft key (or FILE depending on series), and verify the target device is properly mounted. Check DIAGNOSIS screen 0208 for memory card status (0i/30i/31i/32i series).

During file transfer, use READ+EXEC operation. If duplicate exists, the control displays overwrite confirmation. If alarm occurs without prompt, check parameter 3107#1 (OPT) and set to 1 for overwrite capability.

Check parameter 3210#1 (PRG) for program protection status. If set to 1, program input operations may be restricted. Also verify Setting 0/1 input/output enable bits are not blocking program registration.

Do not disable program protection (3210#1) without proper authorization in production environments.

For batch file operations, verify the file list does not contain duplicate O-numbers within the same transfer batch. Edit the source file or use SYSTEM > PARAM > 3107#4 (NCR=1) to enable collation checking before transfer.
