Initialization during automatic restoration
When executing automatic restoration with SD955, set whether or not to initialize the drives other than the SD memory card
with SD955 (restoration function setting) b1 (initialize during automatic restoration). This function is valid only when SD954
(restoration target data setting) is 0 (all target data).
Setting of operation after restoration
Set whether after restoration the CPU module operation is to continue from the backup state or from the initialized state with
SD955 (restoration function setting) b15 (setting of operation after restoration). The operation of each item using the operation
setting after restoration is shown below.
*1 When a battery is not mounted, the start of the SFC program is initial start regardless of setting of operation after restoration.
Note that this setting is invalid since the device initial value file, SFC program, and event history file are not restored when the
value in SD954 (Restoration target data setting) is 1 (restoration target data are only device/label data). Also, this setting is
invalid by restoration with CPU module auto exchange.
