The output register data of the Modbus RTU slaves are mapping in exactly the same way.
The Modbus slave output registers are mapping as the output registers of the EtherNet/IP
adapter of the GW-7472. Users can set the maximum 500 bytes for input data and 500 bytes for
output data which are mapping to the EtherNet/IP adapter of the GW-7472. All of these
configurations are defined by using the GW-7472 Utility tool. While the GW-7472 gets the
EtherNet/IP commands from the EtherNet/IP scanner, it collects the input register data from
Modbus RTU slaves and updates the output register data to the Modbus RTU slaves as soon as
possible.
