Setting method
1.
Perform the refresh settings of the intelligent function module connected to the remote head module.
[Navigation window]  [Parameter]  [Module Information]  Target Module  [Refresh settings]
Specify the following devices as the devices to be refreshed.
Item
"Transfer to the intelligent function module"
"Transfer to the CPU"
2.
Set RWw/RWr ranges assigned to the remote head module in the network configuration setting of the master station.
The number of points should be higher than the number of points set for the refresh settings of the intelligent function module
in step 1 above. (Set the number of points whichever is greater between "Transfer to the intelligent function module" and
"Transfer to the CPU".)
If the number of points will be increased for a system expansion in future, for example, set a large number for
the RWw/RWr setting in the network configuration setting of the master station. Doing so will eliminate the
need to change the parameter setting of the master station at the time of the system expansion. However,
increasing the number of points also increases the processing time.
