When Input Mode is IO
As indicated in the following figure, the inputs from each driver controller (slave) of ID 0 through
F are allocated to the ward device area, or the bits comprising each ward device are allocated to
the driver controller inputs.

Input mode: For simple DVC, half DVC, and full DVC
In addition to driver controller input, input areas for values of position, speed, etc. are allocated.
* Under DVC command, STRT/PWRT signals are invalid.
* For value data maximum and minimum values, confirm with the instruction manual of the driver
controller.

Position data (H) *
(L) indicates the lower 16 bits of the 32-bit integer and (H) the upper 16 bits.
* Setting to a value smaller than the number of digits displayed by D-STEP/TDO is possible, but
the value displayed on D-STEP/TDO will round off the smallest digit (the third decimal place, if
the D-STEP/TDO display shows two decimal places).
As well, when saving data to a file, the value displayed on D-STEP will be saved.
Do not input value data outside the range. Otherwise, it may cause errors, malfunctions, or unforeseen
operation.
