5.2.2 Procedure - Adjusting the Time (When Using System Data Area)

1. From the [Project] menu's [System Settings], click [Display Unit] and open the [System Area] tab.

2. Define the [System Area Start Address] and select the [Enable System Data Area] check box.
   Select the [Clock Data (Preset Value)] check box.
   

3. Write clock data to the address displayed in [Clock Data (Preset Value):(4 Words)] with BCD. You can overwrite clock data if the data rewrite flag (for example, D0010, bit 15) changes (OFF to ON or ON to OFF). The procedure for writing data is as follows.
   

   

   • When bit 15 is ON, clock data is updated when writing data that turns OFF bit 15.

   • You cannot change the "Seconds" data. It is reset to "0" when the clock data is rewritten.
