Registering the Contents of Contact Output (Style Number S3 or Later)
In the same manner as with contact input, you can register actions for contact output and
internal switches. The actions that can be registered are the same as the actions for the
contact input, excluding the 0-3 bit target setpoint setting and the 0-4 bit pattern number
setting.
DIO Operation Control Function (Style Number S3 or Later)
There are 7 types of DIO available.
DI-1:
Displays the input status of the specified DI. The status of the internal
switches is displayed.
DO-1:
The status of the internal switches is output to 1 DO. 1 (ON) is output when
the internal switches are ON, and 0 (OFF) is output when they are OFF.
DO-2:
You can output the ON and OFF statuses of the internal switches to separate
DOs. 1 (ON) is output from the ON output DO when the internal switches are
ON, and 0 (OFF) is output from the OFF output DO when they are OFF. 0
(OFF) is output from the ON output DO when the internal switches are OFF,
and 1 (ON) is output from the OFF output DO when they are ON.
DIO-11:
The same operation as the DO-1 is performed while displaying the input
status of the specified DI.
DIO-12:
The same operation as the DO-2 is performed while displaying the input
status of the specified DI.
DO-2P:
You can output the ON and OFF statuses of the internal switches to separate
DOs. A pulse signal having a 1 to 2 second pulse width is output from the ON
output DO when the internal switches are ON, and from the 0 (OFF) output
DO when they are OFF.
DIO-12P: The same operation as the DO-2P is performed while displaying the input
status of the specified DI.
