Number Of Link Points - Mitsubishi Electric CC-Link IE Basic Reference Manual

Number of link points

The number of link points per slave station is 64 points for RX/RY and 32 points for RWr/RWw. ( Page 8 Performance
Specifications)
However, by changing the number of occupied stations, RX/RY can be set to a maximum of 256 points in increments of 64
points and RWr/RWw can be set to a maximum of 128 points in increments of 32 points. For details on the number of
occupied stations (whether or not the number can be changed), refer to the manual for the slave station used.
If the number of link points for the slave station is changed, the assignment range and station number are changed.
Ex.
Slave station 1
• Slave station 1: 1 station occupied
• Slave station 2: 2 stations occupied
• Slave station 3: 4 stations occupied
The following table lists the number of link points.

Setting the number of link points for a slave station to 2 stations occupied means that two slave stations are
connected. Thus, if the number of link points is increased, the number of connectable slave stations per
network is decreased.
