5.8.3 “1:N topology for report” using example 2
This it the esample using input terminal and output terminal in both master and slave.
Set master to “[I/O] 1:N topology for report” by using setting tool.
●
Report system of central display for alarm by 4 types of equipment and reset alarm by 4
types of equipment.
Routing setting of above system by setting tool
In the above system, slave’s one input terminal should be connected only 1 point as below table.
And if you want to reset alarm individually, output terminal should be connected not to exist same
output from other slaves.
“-“ shows that it is not connected. For example, only ERR1 of slave 01 is connected input 0. Like this
case 2 or more inputs should not be connected to same terminal, any other allocation is OK. Same
as this, 2 or more inputs to master should not be connected to same terminal, any other allocation is
OK.

Notes:
・
In order to transfer input to the other unit, signal should be input over polling time.
・
When signal is input to slave, it reflects to master at polling timing. It delays for
polling time.
・
When reset alarm, signal should be input until disappearing the alarm display with
checking the display. (max. double of polling time.)
