Destination File Too Small

Hva betyr F007 ?

This error occurs when the destination file specified for an operation is too small to accommodate the amount of data requested to be written to it. This prevents the data transfer from completing successfully, leading to data loss or corruption.

• Attempting to write more words than the destination file's allocated size.
• File size limits not properly configured for the destination.
• Dynamic file allocation failed to expand the file.

1. 1

   Inspect the PLC program logic, specifically data transfer or file handling instructions, to identify the source and destination tags/files involved in the operation triggering F007.

2. 2

   Verify the declared size of the destination data array, file, or tag in the PLC program to ensure it can accommodate the amount of data being written.

3. 3

   Check the current memory utilization of the PLC controller (e.g., 'Capacity' in Logix, data file usage in SLC) to ensure sufficient available memory for the operation.

4. 4

   Review configurations of any HMI, SCADA, or external devices that write data to the PLC, confirming the requested write length does not exceed the PLC's destination tag/file size.
