Analog I/O Wiring Example
Note (1) When using a current input, turn ON voltage/current input switch pins IN1
to IN4, and make the suitable setting in the PLC Setup.
(2) For any inputs that are not to be used, set them to not be used by clearing
the selection of the Use checkbox.
If an input that is set to be used is not actually used, the data for that input
