(3) Using link relays in the network system
In order to use link relays in the network system, a network parameter setting is
required.
The link relay range where network parameter setting has not been made (not used
by the MELSECNET/H network system, etc.) is available as the internal relays or
latch relays.
• Range where no link relay latch is performed

POINT
The MELSECNET/H network module includes 16384 link relay points, while the
Basic model QCPU includes 2048 points (default), the High Performance model
QCPU, Process CPU and Redundant CPU include 8192 points(default).
When using the link relays after the above points, change the number of link relay
points in the device setting of the PLC parameter dialog box.
Remark
Refer to the following manual for the network parameters.
