■Data that can be specified
The device other than local device can be specified. However, when "Use File Register of Each Program" is enabled, file
registers cannot be specified. Doing so may prevent the device from operating at file registers for each program depending on
the CPU operating status.

Word Device
*1 This device can be specified only in units of 16 points (one word).
Refresh settings
The refresh can be set up with "Refresh Setting between Multiple CPUs" in "CPU Parameter".
[CPU Parameter]  [Refresh Setting between Multiple CPUs]
Operating procedure
"Refresh Setting between Multiple CPUs" window
"Detailed Setting" window
Set a blank column for "Head" and "End" and set only number of points so that the setting by which auto
refresh is not conducted can be configured. (It is possible to perform setting which does not allow the refresh
data of other CPU modules, which is unwanted for the host CPU module, to be obtained.)
■Enabling timing of refresh settings
The refresh settings are enabled at the following timing:
• When CPU module is powered off and on or is reset.
CPU module operating status and refresh behavior
When the refresh timing coincides with the period specified in the fixed scan communication setting, the refresh behavior
depends on the operating status of the CPU module.
CPU module operating status
RUN (including a continuation error
period)
STOP (including a stop error period
due to a moderate error)
STOP (major error period)
PAUSE
*1 In the disabling interrupt state by the DI instruction, the refresh is not operational, because the multiple CPU synchronous interrupt
program (I45) does not work.
