I-7080, I-7080D, I-7080B, I7080BD User Manual (V 2.2) ------------------ 79
3.2 D/O Operation Principle
(1)
Refer to Sec. 1.8.3 for more information.
(2)
The D/O output of I-7080 & I-7080D modules will be turn OFF
after first power on.
(3)
The D/O output will be changed to the desired state if the
“
@AADO
”
command is received. Then all these D/O will
keep in the same states until next
“
@AADO
”
command.
(4)
If the host watchdog is active, all the D/O will not change and the
module status is set to 04. If the host computer send out
“
@AADO
”
to those modules now, those modules will ignore
this command and return
“
!
”
as warning information. The host
can use
“
~AA1
”
command to clear the module status to 0, then
the I-7080 & I-7080D module will accept the
“
@AADO
”
again.
(5)
If the D/O output is configured as alarm output, the module will
control the ON/OFF state automatically. Therefore the “@AADO”
command will be ignored in this condition.
