Notes:

When the FC6A Series MICROSmart has lost its keep data, the Run/Stop Selection at Memory Backup Error setting has priority over the
Run/Stop Selection at Power Up setting.
 Relays and registers specified as Clear Al l or Clear Specified Range are cleared when the FC6A Series MICROSmart starts operation. The
values while the power is off are retained until the power is turned on and operation is started.

Keep/clear settings cannot be configured for special data registers. They operate the same as Keep All .

Keep/clear settings cannot be configured for special internal relays. For operation when the power is shut off and when stopped, see
"Devices" - "Special Internal Relay" on page 6-4.
Clear All: Clears the internal relays (M0000 to M7997) when the FC6A Series MICROSmart starts operation.
Keep All: Keeps the status of the internal relays (M0000 to M7997) while the FC6A Series MICROSmart power is off.
Keep Specified Range: Keeps the status of the internal relays in the specified range while the FC6A Series MICROSmart power is off.
When a range of M50 through M100 is designated as shown in the example above, M50 through M100 are keep
types, M0 through M47 and M101 through M7997 are clear types.
Clear All: Clears the internal relays (All-in-One CPU module: M10000 to M17497, Plus CPU module: M10000 to M21247)
when the FC6A Series MICROSmart starts operation.
Keep All: Keeps the status of the internal relays (All-in-One CPU module: M10000 to M17497, Plus CPU module: M10000 to
M21247) while the FC6A Series MICROSmart power is off.
Keep Specified Range: Keeps the status of the internal relays in the specified range while the FC6A Series MICROSmart power is off.
Clear All: All shift register bit statuses are cleared at startup (default).
Keep All: All shift register bit statuses are maintained at startup.
Keep Specified Range: A specified range of shift register bits are maintained at startup. Enter the start “keep” number in the left field
and the end “keep” number in the right field. The start “keep” number must be smaller than or equal to the end
“keep” number.
Clear All: All counter current values are cleared at startup.
Keep All: Keeps all counter current values while the FC6A Series MICROSmart power is off.
