POINT
(1) Communication between the Ethernet module and QCPU is performed
according to the Network No., and communication between two Ethernet
modules are performed according to the IP address and UDP port number.
Thus, the Ethernet module must convert the data shown below:
Network No. and station number of MELSECNET/H, MELSECNET/10
IP
address and UDP port number of Ethernet.
(2) The Station No. <-> IP information are required when accessing other stations
via other Ethernet network systems and must be registered in all the QCPU
stations in which the Ethernet modules are installed.
