(a) Insertion and removal of SD memory card
An SD memory card can be inserted/removed after preparation for backup is completed.
(b) Operating status of the CPU module
To backup, the CPU module must be in the STOP status. (When the CPU module is either in the RUN or
PAUSE status, it is switched to the STOP status after the END processing where a request to backup start
preparation was received.)
After replacing the CPU module, it must be powered off and then on or reset. (Failure to do so keeps the CPU
module in the STOP status even after setting the switch to the RUN position.)
Backup start setup is requested
from a programming tool or the backup
startsetup contact is turned on.
