Internal relay
• Link relay range where latch is performed Latch relay
• Although the points for the link relay in a CC-Link IE Controller Network module is 32768, the default for the link
relay in the CPU module is 8192 points.
• Although the points for the link relay in a MELSECNET/H network module is 16384, the default for the link relay in
the CPU module is 8192 points.
To use the link relay exceeding the above points, change the link relay points in the Device tab of the PLC parameter dialog
