3.
Click "Refresh Timing" to set the timing of the refresh operation.
Set "Refresh Timing" 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 "Refresh Group [n] (n: 1-64)" and set a value of 1 to

When the refresh is enabled, the refresh target values will be valid at the timing set in the engineering tool. At
that time, buffer memory areas are overwritten with the refresh target values. To change the values of the
refresh target buffer memory areas, create a program so that the values of module labels or devices of the
refresh source are changed.
