Click "Refresh Group" to set the timing to refresh.
Set "Refresh Group" to "At the Execution Time of END Instruction" or "At the Execution Time of Specified Program".
When "At the Execution Time of Specified Program" is set, double-click "Group [n] (n: 1-64)" and set a value of 1 to 64.
With refresh enabled, the value of the refresh destination takes effect at the timing of refresh which is set up
by the engineering tool. As this happens, the buffer memory is overwritten with the value of the refresh
destination. To change the value of a buffer memory area to be refreshed, change the value of module label or
device at the refresh destination in the program.
