Note If there is an error in the setup data or if the file could not be read, the File
Read/Write Error bit in Unit Status 2 (word n + 11, bit 08) will turn ON.
3. Saving Files from Configurator to Memory Card
Device parameter files (.dvf files) for this DeviceNet Unit that have been cre-
ated using the Configurator can be saved on the Memory Card via the HMC-
AP001 Memory Card Adaptor as file name DNnnBKUP.dvf (where nn is the
Unit number in 2-digit hexadecimal). This DeviceNet Unit can be mounted to
the CPU Unit and, by turning ON the Unit Setup File Restore Switch (word n,
bit 14), the setup data can be restored to the DeviceNet Unit.
Note The file name when saving setup data to the Memory Card must be DNnn-
BKUP.dvf (where nn is the Unit number in 2-digit hexadecimal). For example,
for unit number 00, the file name must be DN00BKUP.dvf. If the file is saved
under another name, the data cannot be restored from the Memory Card to
the DeviceNet Unit.
