“slave 2” is added in lower right of “slave 1” if click “OK”.
Initial asterisk (
＊
) of name means that it is not reflected to master unit. (2) after name means Unit
No. 2. Sharp (
＃
) indicates that terminal is not set. (After entering terminal,
＃
is cleared and after
completing transfer to master and transfer from master,
＊
is cleared.)
Upper slave works as repeater for lower slave.
In this case, “slave 1” has repeater function to “slave 2”.
Therefore, upper slave can transfer data to both a terminal connected itself and another slave.
(7) Add another slave to master.
Click one master in routing table as same as (5), and select “Routing Setting” -> “Slave Unit Setup”
-> “New”.
It is added as below.
Adding slaves by this way makes 1:N topology system.
At 1:N topology, only slaves’ routing setting is not enough to specify a terminal is connected to
which slave. Deciding a relation of terminal equipment and slave makes master communicate to
terminal automatically.
Create new terminal equipment
