-V1), proper backup will not be possible if the backup file
(BACKUPE1.PRM) remains in the Memory Card.
In order to use the Simple Backup Function in this combination, delete the
backup file (BACKUPE1.PRM) inside the Memory Card, then execute the backup.
If backup is executed without deleting this backup file, the RDY LED and the
CPU Unit’s ERR/ARM LED will both flash, and t
he Protocol Data Error Flag (bit
A42409) will turn ON with the restore operation. The
Serial Communications Board
will also automatically delete the
backup file (BACKUPE1.PRM).
Applications Use the Simple Backup Function when replacing all Units or creating backup
files of all of the PLC’s data, including the data in the CPU Unit and Serial
Communications Boards or Units.
Operation Use the following procedures to create a Protocol Data File on the Memory
Card, restore the Protocol Data File, and compare the protocol data with the
Memory Card’s Protocol Data File.
