(1) What is multiple network system
The multiple network system is a network system in which multiple networks are
connected via relay stations.
(a) Duplicated setting of a network number is not allowed. The network number
can be freely set within a range from 1 to 239 unless the same number is
used two or more times in a system.
(b) A maximum of 4 network modules can be installed per programmable
controller.
Note that there are restrictions on the number of modules that can be
installed to each programmable controller, depending on the CPU module
model. (Refer to Section 2.2.).

POINT
Only one network module can be mounted to the Basic model QCPU and safety
CPU.
For this reason, these CPUs cannot be used as relay stations when constructing a
multiple network system using the MELSECNET/H.
