Press the RECALL alarm softkey to clear the informational message from the display.

Verify which program is currently loaded by checking the program manager (Program Manager key) and reviewing the active program list in memory.

If you need to reload the program, first unload or delete the existing version using the program manager delete function before attempting to reload.

Ensure the program is not currently selected or executing before deletion.

If the currently loaded version is correct, simply proceed with program execution without reloading - acknowledge the message and continue operations.

Check the PLC program for automatic file loading routines, particularly in initialization or program-start sequences (review DB and FB blocks managing file operations).

Modify the PLC logic to include a memory status check before issuing load commands - use system variable $P_SEARCH or directory query functions to verify program status.

Test PLC modifications in simulation or safe mode before deploying to production.

Review HMI user cycles or macros that may contain repetitive load commands, especially custom softkeys or automatic cycle start sequences.

Implement conditional loading logic that only executes load commands when the target memory location is confirmed empty or when content differs from source file.

Check network communication status between the CNC and file server - review TCU (Thin Client Unit) connection status in the system diagnostics menu.

Verify DNC settings in the machine data (MD11210-11290 series) for timeout and retry parameters, adjust timeout values if network latency is causing premature retries.

Document original machine data values before making changes.

Review the file transfer protocol settings - ensure proper handshaking and acknowledgment signals are configured for your network architecture.

If using external CAM software or post-processor with automatic file sending, configure the software to verify successful transfer before retry attempts.
