Serial Communication
1:1 Connection
A communication port is selectable from CN1, MJ1, and MJ2.
For more information, refer to “ 1 : 1 Connection” (page 1-8) in “1.3 Connection Methods”.
1:n Connection
A communication port is selectable from CN1, MJ1, and MJ2. A maximum of 31 units of the same model can be
connected to each port.
For more information, refer to “ 1:n Connection (Multi-drop)” (page 1-14) in “1.3 Connection Methods”.
3-way Connection
The V9 series is allowed to communicate with three different models of devices at the same time via three serial ports. A
maximum of 31 units of the same model can be connected to each port.
The connection method is the same as those for 1 : 1 and 1 : n.
n : 1 Connection (Under development)
Multiple V9 units can be connected to one PLC or temperature controller.
For more information, refer to “ n : 1 Connection (Multi-link2) (Under Development)” (page 1-17), “ n: 1 Connection
(Multi-link2 (Ethernet)) (Under Development)” (page 1-25), “ n:1 Connection (Multi-link) (Under Development)” (page
1-31) in “1.3 Connection Methods”.
n : n Connection (Under development)
Multiple V9 units can be connected to multiple PLCs.
For more information, refer to “ n : n Connection (1: n Multi-link2 (Ethernet)) (Under Development)” (page 1-28) in “1.3
Connection Methods”.
