Refresh setting

With this refresh settings, the read and write processing by a program is not necessary.
Set a device/module label of the CPU module which transfers data alternately with the buffer memory on C24.
The device/module label to be transmitted is selected from the following from "Target".
• Module label
• Refresh Data Register (RD)
• Device
Module label
The contents are transferred alternatively between the module label corresponding to each buffer memory and the buffer
memory. Set "Valid" for the item to be transferred using module labels and "Invalid" for the item not to be transferred. By
enabling "Send data_send area", the other transfer destinations will be set to "Valid".
Refresh data register (RD)
The contents are transferred alternatively between the refresh data register (RD) of a CPU module and the buffer memory. By
setting the refresh data register (RD) to be transferred in "Top Device Name", the other transfer destinations will be
automatically set.
Device
The contents are transferred alternatively between the designated device of a CPU module and the buffer memory. The
devices that can be designated are X, Y, M, L, B, T, C, ST, D, W, R, ZR, and RD. When bit devices, X, Y, M, L, or B are used a
number that can be divided by 16 points (for example, X10, Y120, M16, etc.) should be set. The buffer memory data is stored
in the equivalent of 16 points from the designated device number.
(For example, when X10 is set, data is stored from X10 to X1F.)
