To configure the dates by specifying data registers
The dates for the ON/OFF settings are configured according to the values stored in the specified data registers.
The dates for the ON/OFF settings can be changed while the FC6A Series MICROSmart is running.
Note: When a special date in the ON/OFF settings is modified with the YEAR instruction input turned on, it is not reflected in the output operation
until the current date and time match the changed special date.
To immediately reflect this in the output operation, turn the YEAR instruction off and then on again after changing the special date.

1. Data register settings
This setting selects whether to configure YEAR instruction dates as fixed settings or to indirectly specify them with data
registers.
To configure the dates by specifying data registers, select this check box.
Selected check box
The date settings are indirectly specified by data registers. Configure the dates by using data registers. The dates can be
changed while the FC6A Series MICROSmart is running. For allocating the data register region, see "Data Register
Allocation" on page 11-23.
The data registers can be initialized with the days of the week and the times configured on the parameter tabs by turning on
the initialization input. For initialization, see "3. S2 (source 2): Initialization Input" on page 11-21.
Note: When this check box is not selected, the dates are fixed settings. The dates are configured on the parameter tabs. The dates cannot
be changed while the FC6A Series MICROSmart is running. For fixed settings, see "To configure the dates as a fixed setting" on page 11-17.
2. S1 (source 1): First Data Register
This setting specifies the start of the data register region to store the dates for the YEAR instruction.
This setting is only used when indirectly specifying the dates with data registers.
