Data flow
This section describes the cyclic transmission data flow of word device data and the setting for transmission.
• When data is transferred from the master station to the intelligent device station: The remote register (RWw) data of the
master station is transferred to the buffer memory of the intelligent function module connected to the remote head module.
• When data is transferred from the intelligent device station to the master station: The buffer memory data of the intelligent
function module connected to the remote head module is transferred to the remote register (RWr) of the master station.
■When "0000H" is set to the start I/O number of the RWw/RWr setting of the master station

 Set RWw/RWr ranges assigned to the remote head module in the network configuration setting of the master station.
 Assign 1024 points (W0 to W3FF) from RWw0.
Assign 1024 points (W1000 to W13FF) from RWr0.
 Set the refresh ranges for the remote head module and the buffer memory of the intelligent function module in the refresh settings of the intelligent function
module.
