• The installation of MELSECNET/MINI twisted pair cables needs to be modified according to the upgraded
In the example, optical dual loop is selected to loop the network. When the distance between stations or
overall distance is short, a coaxial bus cable can be used to reduce cable installation time.
• Some CPUs, such as Basic Model QCPUs (Q00J, Q00, Q01CPU), cannot be set as MELSECNET/H
(remote I/O network) master station.
For selecting CPU type, refer to "Q corresponding MELSECNET/H Network System Reference Manual
(Remote I/O network)" SH-080124.
• If modules other than building type I/O modules, such as A2C I/O modules, are mixed in the existing
MELSECNET/MINI(-S3) system, the entire system cannot be upgraded to MELSECNET/H (remote I/O
In this case, consider separating the system into MELSECNET/H (remote I/O network) and CC-Link.
